2.3. Warnings These warnings must be always observed; otherwise, personal injuries or damage to property may occur! Installation site Mains connection Explosive atmospheres Make sure that the machine cabinet is not installed above or right next to water containers. Risk of electric shock if not installed properly. Connect the machine cabinet only to a 230 V socket or earth connection that has been properly installed according to instructions and is protected with a preliminary 16 A fuse in accordance with the technical data. During a thunderstorm, the electrical devices connected to the mains can be damaged. An overvoltage protection in the domestic electrical installation is recommended as protective measure. The connection line must be installed in such a manner that it does not become a tripping hazard. The control must not be installed or switched on in environments with potentially explosive atmospheres or in places where flammable materials exist. In such environments, sparks can cause an explosion or fire and this can, in turn, result in personal injuries or even death. Interferences The control can cause malfunctions of medical equipment. Therefore, the control should not be operated right next to medical devices. Damage The control must not be operated when the housing or the insulation of a line are damaged or pinched. Service work Service work on the machine cabinet may only be performed by authorised specialist personnel and/or electrically skilled persons. After having been replaced, the battery supplied must be properly disposed of. Battery replacement Voltage supply The power supply must be permanently ensured. Please make sure that the control cabinet is sufficiently protected (16 A). Additional power consumers on the same fuse can disrupt the operation. 9

Function of the SBR system KLARO and KLARO Easy are fully biological small wastewater treatment plants that work according to the principle of the SBR method (activated sludge plant in the impoundment method). The SBR plant is designed for the discharge of the entire domestic waste water. The discharge of other wastewater, e.g. the wastewater from restaurants and/or industrial enterprises etc., is only permitted when this was already known and considered when designing the plant. Biocides, toxic or biologically incompatible substances must not enter the plant, since they impede the bacteria important for the wastewater treatment and cause biological process problems (more detailed information is provided on the following pages). In order to comply with the official requirements for treated wastewater, it is absolutely necessary to operate the plant according to our operating and maintenance instructions that can be found on the following pages. In principle, the plant consists of two steps: sludge storage with an integrated pre-buffer and an activated sludge level in the closed impoundment method (SBR reactor). The upstream sludge storage with an integrated buffer performs the following functions: - Storage of primary and secondary sludge, - Retention of settleable solids and floating solids, 10

- Storage of the supply water, - Compensation of volume- and concentration-related fluctuations in inflowing wastewater. The wastewater treatment plant is operated by means of a microprocessor control that drives the aerator and the air distribution for the different lifts via solenoid valves. Your competent water authority has determined limit values for the water quality of the treated wastewater. Accordingly, you have purchased a plant of the effluent class which definitely complies with these limit values. Depending on the certification, both the interval between the prescribed maintenances (at intervals of 4 or 6 months) and the scope of the effluent values to be verified vary. The following table provide an overview of the effluent values of KLARO. KLARO values: KLARO values Degree of efficiency COD BOD 5 NH 4 -N N inorg SS FC germs P tot 39 mg/l 9 mg/l 6,1 mg/l 18,7 mg/l 15 mg/l 1,9/100ml 0,4 mg/l 94,6 % 97,3 % 84,4 % 67,4 % 96,2 % 99,9 % 95,0 % 4.1. Plants for carbon elimination (effluent classes C) This method is a sequence of five work steps that are carried out one after the other and are repeated several times a day (normally four times). - Work step 1 (valve 1) : feed - The raw wastewater stored temporarily in the sludge storage is led to the SBR reactor via an air lift. This reactor is positioned in such a manner that only water free of solids is pumped. By means of a special design of the lift, a minimum water level in the sludge storage is guaranteed. Thus, the limitation of the water level using further components (e.g. by means of a float switch) is not necessary. - Work step 2 (valve 2): ventilation During this work step, the wastewater is aerated and mixed. The ventilation is provided by diaphragm tubes or plates installed on the chamber bottom. The ventilation device of the plant is supplied with ambient air by an externally installed control cabinet. The required air is generated by an aerator. The ventilation is normally operated intermittently. Figure 1: Diaphragm tube aerator Figure 2: Diaphragm plate aerator 11

This ventilation causes two effects at the same time: The micro-organisms of the activated sludge are supplied with oxygen that is required for their metabolic activity and, thus for the degradation of the contaminants. There is intensive contact between wastewater and bacteria. - Work step 3: settling phase This work step constitutes a resting phase, during which no ventilation takes place. The activated sludge can settle according to the principle of gravity (sedimentation phase). In the upper area, a clearwater zone develops and a sludge layer at the bottom. Any occurring floating sludge is above the clearwater zone. - Work step 4 (valve 3): clearwater extraction During this phase, the biologically treated wastewater (clearwater) is pumped out of the SBR step. This pumping process is carried out by means of air according to the airlift pump principle (air lift). The air lift is designed in such a manner that any occurring floating sludge on the clearwater layer is not pumped. A minimum water level in the SBR step is kept without any further components. - Work step 5 (valve 4): excess sludge extraction During this working step, excess activated sludge by means of the air lift is led back from the SBR reactor chamber into the sludge storage chamber and stored there. This excess sludge is pumped close to the bottom of the SBR chamber. After this fifth work step has been completed, the treatment process can start again with work step 1. Four of the cycles described above are normally processed per day. An individual adjustment of the switching times and the cycle number is possible after consultation with. This adjustment may only be carried out by an authorised specialised maintenance company. In addition to this, it is possible to manually switch the plant into the vacation mode. The vacation mode is a significantly reduced operation of the plant during longer periods of time without inflowing wastewater. By means of the KLplus control, the plant can be operated depending on the actual amount of wastewater. For this, the fill-level detection must be activated by a specialist. Important: All chambers / containers must be aerated. This is normally performed by the wastewater line vented via the roof. If required, additional ventilation lines or ventilation openings must be installed. In doing so, the ventilation lines must be positioned in such a manner that natural ventilation is possible (chimney effect). 4.2. Plants with additional nitrogen elimination The nitrogen degradation is also carried out biologically by means of certain strains of micro-organisms. Plants with additional nitrification create, by means of particularly intensive ventilation, optimum living conditions for nitrifying bacteria which convert ammonia to nitrate. In plants designed for additional denitrification, the circulation of the water and activation of the denitrifying bacteria are achieved by short 12

aeration periods at the beginning of the ventilation phase. These bacteria transform nitrate into elementary nitrogen. 4.3. Plants with additional phosphate elimination The phosphate precipitation is carried out by adding polyaluminium chloride in the SBR reactor. A removable supporting platform in the dome or on the dividing wall of the container is part of the phosphate precipitation unit. The precipitant canister is on this platform. The switch cabinet of the plant is equipped with a dosing pump. This dosing pump draws the precipitant out of the precipitant canister and releases the precipitant in the SBR reactor. The precipitant is added during the feed phase of the reactor. The precipitant quantity required can be set by means of the dosing pump. The mixing takes place during the ventilation phase. Together with the phosphate, the precipitant forms an indissoluble compound that settles well in the container. The commissioning and handling of the pump is described in section 6.2.4. 4.4. Plants with additional hygienisation The additional KLARO UV module is used for sterilising the biologically treated wastewater. The germs in the wastewater are removed by means of ultraviolet light (UV). This is an effective, economic and particularly environmentally friendly method. UV light eliminates pathogenic micro-organisms within seconds without residues, harmful by-products or reduction of quality through odours. The effect of the UV light is made use of by means of particularly effective UVC radiation (254 nm). Within a few seconds, it causes a photochemical reaction in the DNA (deoxyribonucleic acid) that is vital for all microorganisms. As a result of this, the micro-organism is either eliminated or its ability to multiply is destroyed. With the UV dose values used for sterilisation, the UV irradiation does not cause any undesirable side reactions. Since no disinfection-effective substance is added to the water due to the UV irradiation, there are no depot effects after the water has passed the UV reactor. 5. The control of the small wastewater treatment plant The plant is operated by means of the control in the cabinet door (and/or in the interior of the cabinet with outdoors cabinets). The control allows setting the operational parameters, displaying the operating states and querying the plant parameters. Furthermore, the operating times can be programmed by a specialised company. In the automatic mode, the contrast of the display can be changed by pressing the ESC and the arrow keys at the same time. The following figures show the structure of the control units. 13

Replacing fuses Before replacing the fuses, the plant must be switched off by means of the red main switch! In order to replace or check fuses, the control and machine cabinet must be opened with the key supplied. The micro-fuses described above are on the rear of the control. Used fuses: Micro-fuse Supply line F1 Consumer F2 230 V / 50 Hz 8 A, medium time lag 2 A, time lag In order to replace the micro-fuses, please proceed as follows: Turn the head of the holder by applying slight pressure and using a slot screwdriver SL 1.0 x 5.5 for a quarter turn to the left (anti-clockwise). 20

Remove the head of the holder with the fuse. Replace the fuse. Insert the head with the fuse into the opening of the holder. Gently press on the head of the holder using a screwdriver and fix the fuse by turning the head for a quarter turn to the right (clockwise). Note: If you are not able to solve the problem, please contact your maintenance company or KLARO as soon as possible. 5.4. Functional principle of the power outage detection device The control is equipped with a power outage detection device that is powered by an integrated emergency power supply (buffering). In the delivery state, the emergency power supply is empty. It is charged after the control has been switched on. In the event of a blackout, the charge of an emergency power supply is sufficient for signalising the power outage for approx. 12 hours. If the emergency power supply is not used to compensate power outages, the discharge of the emergency power supply is prevented from being discharged by means of a circuit. Important: In the event of a power outage, the setting of the time / date is supplied with power by means of an additional buffering for a period of approx. 10 days. All saved data such as operating hours, programme settings etc. are preserved. If, however, date and time have not been set, weekly operating hours of the aggregates are no longer saved. Future error messages are then saved with an incorrect date. If the plant is disconnected from the mains (e.g. due to a blackout, when the internal fuse is blown or when separated from the wall socket), the detection device sends alternately an acoustic and visual signal regardless of the actual cause. The device reacts to a power outage with a delay of five seconds. This prevents that short outages that often occur, for instance, during a thunderstorm, but do not impair the overall function of the wastewater treatment plant, are unnecessarily signalled. - The five-second delay is followed by an intermittent with a read flashing signal. At intervals of five seconds, five flashing signals are continually sent with a beep for a period of approx. 12 hours (with a completely charged emergency power supply). - Switching off the device is not possible in this state. When the mains voltage returns, the device is reset to the monitoring state without any further keys being pressed and the control continues to run from the point at which it was interrupted. The fault message disappears automatically. When the emergency power supply is discharged, the operation of the plant is restarted with a cycle pause. Blackout Attention: If the plant has been disconnected from the mains for more than 24 hours, the purification of the existing wastewater is not possible or only possible to a very restricted extent. Never switch off the plant (except for maintenance of plant components and function-restricting faults of the plant) 21

6. Additional functions of the KLplus and KLbasic controls 6.1. Underload detection (KLplus) Malfunction Attention: The activation of the fill-level-dependent mode must be carried out by a maintenance technician or an export. Any incorrect calibration of the plant can cause that the plant is permanently run in the saving mode (cycle pause)! In this case, proper purification is not possible! As standard, the KLplus control is equipped with a pressure sensor by means of which the fill level in the first chamber can be determined. This function is used for saving energy with low amounts of inflowing wastewater. This function is switched off in the delivery state. During commissioning, the plant is run in the automatic mode regardless of the amount of inflowing wastewater. 22

6.1.1. Functional principle The water level is measured by means of the pressure in the feed lift during the feed phase. If the water level in the sludge storage / buffer (chamber 1) exceeds a previously set fill-level height ( Fill-level detection setting ), the plant starts a purification cycle. If the fill level is not reached, the plant enters the cycle pause for a period of six hours. During this cycle pause, the SBR reactor is only aerated sporadically in order to keep the bacteria alive. If the previously set water level was not reached in the first chamber after four subsequent measurements, the plant pumps, via the excess sludge lift, water out of the reactor and back into the first chamber. After the water has been pumped back, the plant measures the water level again. With no or little inflowing wastewater, the reactor is thus also fed after a certain period of Figure 9: Drawing air lifter charging time. Hence, the normal purification performance can also be maintained for a longer period of time in times of absence or underload. The number of the purification cycles performed can be queried via the menu item operating hours. In doing so, the actually performed purification cycles are placed in relation to the cycles carried out in the automatic mode (four cycles a day) and displayed as a percentage (capacity of 25 % to 100 %). 6.1.2. Commissioning Fall hazard During any work on the opened cover of the cesspit, there is a tripping and fall hazard! The open pit must be secured by means of suitable measures. The first chamber (sludge storage / buffer) equipped with the feed lift must be filled with water up to the height at which a purification cycle is to be activated. This water level depends on the geometry of the container and the connected PE. In the following table, the recommended buffer heights a above the minimum water level are stated for the different constellations. 23

Please carefully follow the instructions provided below: Service code enter calibrate? no measuring Go to the menu item ENTER SERVICE CODE, press the key and enter the following code after having been requested to do so: 9 9 9 9. Select CALIBRATION YES by using the arrow keys ( ), confirm this input by pressing the key and start calibration Three measurement processes are carried out automatically. 24

enter current water level: 000 cm Enter the current fill level b of chamber 1 measured by you using the folding metre stock (measured from the bottom of the container to the water surface) save? cm No and confirm this input by pressing. The value entered here indicates the distance c from the bottom of the container to the feeding point of the lift. Select Save Yes by using the arrow keys ( ) and confirm this input by pressing the key. The calibration has now been completed and you can exit this menu by pressing the ESC key. 2 nd step: setting the control parameters Setting the control parameters for the fill-level detection is absolutely necessary in order to ensure that the plant works correctly. Please carefully follow the instructions provided below: service code enter level measuring setup Fill level Start from: 000 cm Recirculation: 2 min alert flooding from: 000 cm Go to the menu item ENTER SERVICE CODE, press the key and enter the service code after having been requested to do so. Select Set fill-level detection by using the arrow key to the left ( ) and confirm this input by pressing the key. Enter the water level b at which a treatment cycle is to be started. Confirm this input by pressing the key. Enter the value 2 min using the number keys and confirm this input by pressing the key. The required settings have now been completed and you can exit the menu by pressing the ESC key. (As from software version 8.29) NOTE: The activation of the flood warning message is not absolutely necessary in order to ensure that the plant works correctly. When saving the value 000 cm, this warning message remains deactivated. In order to activate this warning message, measure the height between the bottom of the container and the lower edge of the emergency overflow in the dividing wall or, with full circle plants, at the outlet. With containers, you can enter the value applicable to your plant from the table above. The designation of your container can be found on the corresponding delivery note. Confirm this input by pressing the key. When saving the value 000 cm, the flood warning message is deactivated. 3 rd step: function control Now, the fill-level detection can also be carried out in the manual mode. For this, the fill-level detection must be switched on using the number 1. The control independently performs a measurement. After this measurement process has been completed, the measured value is displayed. 6.1.3. Switching off the fill-level detection In order to switch off the fill-level detection and have the cycles run again in the time-controlled mode, the 2 nd step described above must be repeated. The water level b must be set to 0 cm. The recirculation can remain set to two minutes. 25

6.1.4. Safety and fault messages If the sensor measures a value of less than 40 mbar, the message Fault: min. fill level appears on the display. In this case, the plant returns to the normal time-controlled mode. This can be attributed to either too low a water level ( 40 cm) in the sludge storage / buffer or a leakage in the pressure or measuring hose. In this case, we recommend you to contact the manufacturer. 6.2. Optional additional functions with extension cable (KLplus and KLbasic) By connecting an additional cable to the connection X3 or X4, the range of functions of the control can be extended. The following extensions are possible: ST5 Connection of a phosphate dosing pump ( X3), ST6 Connection of an external alarm unit ( X4), also for KLbasic, ST7 Monitoring of a contactor for a three-phase current compressor ( X4), ST8 Connection of a UV reactor ( X3). 6.2.1. Connection of an external fault indicator Via the potential-free output ST6, an external alarm unit such as an indicator lamp mounted to the outside of the cabinet can be connected. More detailed information can be found in the MoAnl 10 Externe Warnmelder [InstInstr 10 external alarm unit]. 6.2.2. Connection of a connector for switching the compressor If the power supply of the installed compressor is higher than 6 amperes, a contactor is additionally installed in the cabinet by means of which the compressor is driven. Via the input Contactor monitoring ST7, the switching state of the contactor is monitored. 6.2.3. Connection of a UV reactor Via the connection ST8, a downstream UV reactor can be connected to the control. More detailed information can be found in the MoAnl 11 UV-Anlagen [InstInstr 11 UV plants]. 6.2.4. Phosphate precipitation using the dosing pump Precipitant Attention: When swallowed, iron(iii)-chloride is harmful to health and also irritates the skin. There is a risk of serious injury to the eyes. There is an explosion hazard in connection with alkali metals, allyl chloride and ethylene oxide. Read the corresponding safety datasheet before using phosphate precipitants! When handling iron(iii)-chloride, protective clothing must be worn. Keep precipitant containers away from unauthorised access by others and children. 26

Plants delivered with the phosphate precipitation function are equipped with a hose pump in the cabinet. A suction hose and a pressure hose are connected to the pump. The runtime of the hose pump is determined by the time set for the pump in the service menu. The amount of the added precipitant thus depends on the set time. The large pump Compact is equipped with a potentiometer for setting the performance. The table below provides an overview of the dosing possibilities. The respectively required dosage can be found in the respective certification (see CD). In order to commission the precipitation unit, the container with the precipitant must be installed in a frost-proof place (e.g. machine cabinet, either on the dividing wall or in the Figure 10: System drawing precipitation unit dome-shaped manhole of the plant). The pressure hose and the suction hose must also be installed in a frost-proof place. The pressure hose must be inserted into the SBR reactor and positioned in such a manner in the reactor that the outlet opening is above the reactor tank and it is ensured that the precipitant falls directly into the wastewater to be treated and does not wet any components (aggressive chemical, risk of damage to the components!). The outlet opening must, under no circumstances, be immersed into the water! Insert the suction hose into the precipitant container to the extent that the suction from the bottom is ensured. Connect the suction hose and pressure hose to the hose coupling nipples of the pump and fix them using the union nuts. Under the menu item Manual mode, switch on the phosphate pump and check whether the precipitant is sucked correctly. If required, interchange the hoses at the connections.

7. Maintenance, servicing and operation The plant must be switched on at any time. As operator of a small wastewater treatment plant, you are obliged to ensure the error-free operation of the plant. Almost all operational breakdowns cause a deterioration of the purification performance of the plant. Therefore, these operational breakdowns must be detected at an early stage and rectified by you or by a qualified maintenance technician. During any work on the opened cover of cesspit, there is a tripping and fall hazard! The open pit must be secured by suitable measures. Persons involved and/or third parties may fall into the container! Children are particularly at risk! Fall hazard Due to the biological degradation processes in small wastewater treatment plants, the generation of (possibly toxic) gases must be expected. Therefore, entering the plant must always be secured by a second person. In any case, a fainted person must not be followed, but help must be sought as soon as possible. High voltage For activities other than operating the control, the maintenance switch must be set to 0 and/or the mains plug of the cabinet must be pulled out! Any maintenance and repair work on the cabinet system must be carried out by a maintenance technician or an electrician! 28

7.1. Tasks of the operator In order to ensure an error-free operation, the following checks must be performed: 7.1.1. Daily check - It must be checked whether the plant is run properly. This is the case if the operating indicator lamp lights up green and no warning signal can be heard. A fault is displayed as described in chapter control of the plant. In the event of an incident, we ask you to read the liquid crystal display and to inform the service personnel about the displayed fault or, if possible, to rectify the fault yourself. 7.1.2. Weekly checks - Checking the water levels; sludge must not enter the SBR chamber in an uncontrolled manner, - Checking the inlets and outlets for clogging (visual check), - Reading the operating hours counters of the aerator (total operating hours), the ventilation (valve 2) and the sludge return (valve 4), if required, also the operating hours counter of further aggregates and recording them in the operation log, - Function control of the lifts and the ventilation via the setting Manual mode. 7.1.3. Monthly checks - Visual check for any sludge overflow, blurring or discolouration in the outlet, - Checking the inlets and outlets for clogging (visual check), - Reading the operating hours counters of the aerator (total operating hours), the ventilation (valve 2) and the sludge return (valve 4), if required, also the operating hours counters of further aggregates and recording them in the operation log, - Checking the air filter: The filter of the switch cabinet ventilation (ventilation grilles on the left and right side in the housing wall with an inside cabinet and/or on the rear with an outdoors cabinet) must be checked and, if required, cleaned or replaced. For this, the grilles on the outside of the cabinet must be removed. The snap lock can be unlocked by applying slight pressure and using a screwdriver and the grille can be removed by hand. The filter mat lies, without any further fastening means, in the ventilation pit and can be shaken out and/or blown out. The interval at which the filter of the aerator must be cleaned or replaced depends on the extent of contamination caused by the atmospheric conditions around the application. In order to check or replace the filter on the compressor, the service documentation of the compressor manufacturer provided in the annex must be complied with. - Checking the phosphate precipitation unit (if any): function control of the precipitant pump and checking the fill level of the precipitant container, - Checking the function of the power outage alarm unit. 7.1.4. Sludge drainage In a small wastewater treatment plant, there are different types of sludge. Only the faecal sludge that accumulates in the first chamber is removed. It consists of sedimented residues resulting from the wastewater treatment. In small wastewater treatment plants, the faecal sludge and/or sewage sludge consists of dead micro-organisms of the biological treatment stage and the settled solids resulting from the pre-cleaning. The height of the accumulated sludge in the sludge storage is measured by skilled maintenance personnel using a sludge pipette. The plant is designed in such a manner that, with permanent full-load operation and compliance with the operator and maintenance obligations, the 29

sludge storage room is large enough for at least twelve months. Low-load operation extends this period of time accordingly. Timely sludge disposal is necessary in order to prevent the solids from entering the biological stage in the event of increasing sludge production. Sludge regulation and disposal are important requirements for a good purification performance and long life of the small wastewater treatment plant. The sludge disposal regulations are laid down by the local authorities. Either regular or demand-oriented sludge removal is required: - Regular sludge removal takes places on specific dates and is set by the local authorities to once and/or twice a year depending on the type of the plant, size of the chambers and connected inhabitants. - Demand-oriented sludge removal is flexible and takes place at shorter or longer time intervals. In this case, skilled maintenance personnel check the sludge level (sludge level measurement) and inform the competent disposal company about the date of the required sludge disposal. With a filling of the sludge storage of 70 % at the latest, the sludge must be disposed of. In individual cases, the skilled maintenance personnel inform the operator who then arranges himself/herself a date for the sludge disposal. If the maintenance and the sludge removal coincide, the sludge may only be removed after the maintenance has been completed. The sludge removal must be recorded in the operating log. In this respect, please also read the instructions provided by your specialist company. For the sludge removal, the following aspects must be observed: In most cases, only the primary settlement chamber of the small wastewater treatment plant must be emptied. With an incorrect sludge regulation of the plant, the suction of the lower section of the tertiary treatment chamber or the suction of the floating sludge from the surface may also be necessary. First, the floating sludge is sucked from the surface; then, the suction tube is placed on the bottom of the pit, A residual amount of water of approx. 10 cm should be left on the bottom of the primary settlement chamber, After the drainage has been completed, the primary settlement chamber must be refilled with fresh water! Complete drainage of the small wastewater treatment plant only makes sense if an operational breakdown occurs for which the cause cannot be determined or if repair work must be performed below the water level inside the container. Whether such complete drainage is necessary is best decided by the skilled maintenance personnel. It is essential that you, as operator of a small wastewater treatment plant, ensure that the correct chamber of the plant is pumped. Excessive pumping of sludge can interfere with the operation of a small wastewater treatment plant and causes unnecessary costs! 30

7.2. Maintenance and servicing by skilled maintenance personnel The maintenance must be carried out by a specialised company (skilled personnel) 1. For this, the owner of the plant must conclude a maintenance contract with a qualified specialist. Note! During retrofitting work or maintenance work on the electrical components of the plant, the control cabinet must be disconnected from the power supply by means of a main switch or maintenance switch of the plant. It must be ensured that the switch is protected against being switched on by means of a lock. The following work must be performed as part of the maintenance: - Inspection of the operating instructions including assessing that the plant works properly (target/actual performance comparison), - Checking the air filter of the aerator and the supply and exhaust air openings of the control cabinet, - Maintenance of the aerator according to manufacturer s instructions (see annexes!). - Function control of the operation-critical mechanical, electro-technical and other components of the plant such as the aerator, lift, control unit, valves, alarm unit and the battery of the power outage detection device, - Checking the sludge height in the sludge storage; if required, the sludge removal must be provided for by the operator (for instructions, see section 0), - Performing general cleaning work, e.g. removal of deposits, - Checking the state of repair of the plant, - Checking sufficient ventilation and exhaustion, - Examinations in the aeration tank: Even ventilation picture (bubble picture), Oxygen concentration (O 2 /l > 2 mg); if required, adjustment of the operating times of the compressor, Sludge volume fraction (< 400 ml/l). If the sludge volume is below 100 ml/l or above 400 ml/l, the duration of the sludge extraction must be changed in consultation with. - Samples from the outlet and analysis of the following values: For each maintenance: - Temperature of the wastewater, - Settleable solids, - ph value, - Odour, - Colour, - Visibility depth, - COD value, - NH4-N (when required), - N inorg (when required), P (when required). 1 Specialised companies are operator-independent companies whose employees (skilled personnel) have, due to their professional training and participation in relevant qualification measures, the qualification required for the operation and maintenance of small wastewater treatment plants. 31

Any performed maintenance work as well as any detected damage or repair work carried out and further action must be summarised in a maintenance report by the maintenance company. The corresponding form can be found in the annex. The findings of the examinations must also be recorded in the maintenance report. The maintenance report must be handed over to the operator of the plant so that this report can be submitted to the competent authority after having been requested to do so. The maintenance report must be attached to the operating instructions. Please keep the operation log easily accessible. Note: Breakdowns of the plant due to inadequate maintenance (e.g. of the compressor) exclude free replacement within the scope of warranty. 7.3. Operating instructions As a matter of principle, only substances that, due to their nature, correspond to domestic untreated wastewater may be supplied to the plant for treatment. Biocides, toxic or biologically incompatible or non-degradable substances must not enter the plant, since they cause biological process problems. In particular, the following substances must not be discharged: - Rainwater from roof surfaces and courtyard areas, - Infiltration water (e.g. drainage water), - Residues arising from animal farming in solid and liquid form, - Commercial or agricultural untreated wastewater provided that it cannot be compared with domestic untreated wastewater, - Chemicals, pharmaceuticals, mineral oils, solvents, - Cooling water, - Coarse substances in the form of leftovers, plastics and sanitary products, coffee filter bags, bottle lids and other household items, - Milk and dairy products, - Discharge water from swimming pools, - Larger quantities of blood. If larger quantities of fats or vegetable oils accumulate, it is recommended to pre-clean the fat-containing wastewater in a fat separator that is installed upstream to the wastewater treatment plant (Caution: Faeces must not be discharged into the fat separator!). In the table below, individual substances that must not be disposed of using the wastewater treatment plant are listed once more in more detail: Solid or liquid substances that must not be disposed of using What damage they do: Where they are adequately disposed of: the drain and/or toilet: Adhesive plaster Clogs the pipes Dustbin Ash Does not decompose Dustbin Bird sand, cat litter Causes deposits and clogging of the Dustbin pipes Brush cleaners Poison the wastewater Collection point of the administrative district Cat litter Clogs the pipes Dustbin Cement water Settles, concretes Hire specialist company 32

ATTENTION To Prevent Electric Shock And Fire 1 Don, t install the blower where it will be flooded with water. 2 Electrical work must be done by a qualified electrician. 3 The power supply should be the rated voltage shown on the label on the blower and be fitted with an earth leakage breaker and over current breaker. 4 The power outlet used should be waterproof and include an earth connected to ground. 5 If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or similarly qualified person in order to avoid a hazard. 6 Don, t place any objects on the electric cable. 7 Be sure to unplug the blower before starting maintenance. 8 Be sure to put the Upper Case back after maintenance. 9 Don, t touch the metal part of the blower until it is cooled down as the blower runs very hot. Ignoring any of the above may cause an electric shock, a fire or a burn. 3 55

4. Installation (Septic Tank Application) 1. Installation site selection 1 9 Install our blower near the septic tank. If the pipeline is long, the sewage treatment may not perform well due to an insufficient airflow. Install in a place which is convenient for maintenance. Don, t install over a manhole or on soft ground. Avoid areas where wind-blown leaves and dust gathers. Install in a well ventilated place. Install at least 30cm away from the wall of a house. Installation in the shade is recommended to suppress heat generation of the blower., Don t install the blower where it will be flooded with water. Make sure that the blower is installed over the water level ot the sewage tank/aquarium to avoid any backflow of the water. If the blower is installed under the water level a backflow valve must be used. Don, t install where there is excess moisture or humidity. 2. Method of Installation 1 2 9 10 2 3 4 5 6 7 8 3 4 5 6 7 8 11 The base should be made of concrete strong enough to bear the weight and block vibration from the blower. The base should be at least 10cm above the ground level and 5cm larger than the external dimensions of the blower. Provide a separate power outlet to be only used for the blower. Electrical work must be done by a qualified electrician. The power supply should be the rated voltage shown on the label on the blower and be fitted with an earth leakage breaker and over-current breaker. The power outlet used should be waterproof and include an earth connected to ground. Place the blower horizontally on the base. A soft rubber hose must be used for connection between the air outlet of the blower and the pipe. The rubber hose must be fastened with hose clamps. When making the connection, level the air outlet and the pipe to ensure the hose is not kinked or blocked. Before starting the operation of the blower, ensure that the water level in the septic tank is appropriate and the valves on the pipeline are properly opened. 3. Start operation Insert the power plug into the power outlet with full contact so that the plug itself does not wobble. Incomplete connection may cause an electric shock or a fire. After starting operation ensure that there is; No air leakage from the hose and the pipe connection. No abnormal noise from the blower. No vibration transmitted to the ground due to strained piping.

L1 L2 L1 L2 L3 L3 Operating Manual for SBR small wastewater treatment systems 13.2. Becker and Rietschle rotary slide compressors Note: The Becker rotary slide compressors used by us are equipped with a pressure control valve that is factory pre-set to a maximum pressure of 0.5 bar. With our plants, an operating pressure of < 0.3 bar is common. If a pressure of > 0.5 bar (e.g. due to a bent air hose) occurs at the plant, a part of the air is blown off via the pressure control valve. Thus, the compressor is protected against damage or excessive wear and tear. 1. Warning Notice High Voltage Only qualified staff may work on electronic components High Voltage according to ANSI American, National StandardsInstitute Qualified Staff Marked operations may only be executed by qualified electricians Automatic Start-Up When servicing the device must be turned off Hot Surface will cause burns. Let device cool down before maintenance Note Ignoring notices will cause severe damage to the pump 2.
