1 Optimal cotrol of water supply systems

2 Cotext OPIR Predictio: improved performace ad optimal water quality The past te years have witessed a tred toward improvig drikig water productio ad distributio by optimizig the cotrol of water supply systems. This tred has bee reiforced by the followig factors: Eergy cosumptio ad costs are becomig a icreasigly importat cosideratio. Variatios i local demographic coditios are leadig to sigificat icreases or decreases i water cosumptio. Icreasig attetio is beig focused o moitorig ad reducig water losses, with the objective of achievig sustaiable operatios. Istrumetatio ad cotrol are rapidly improvig ad becomig more cost-effective, allowig for fully automated plat operatio. OPIR is a advaced cotrol software product which optimizes the operatio of water productio ad trasport facilities, prevets turbidity peaks i the clea water, ad reduces eergy cosumptio i water supply systems. OPIR is the product of decades of experiece with cotrol systems i umerous water supply systems, ad is based o i-depth kowledge of productio ad distributio processes. OPIR s adaptive demad forecast allows for costat water productio through the optimal use of the available water storage. OPIR ca optimize the operatio of ay water supply system: urba or rural, large or small, basic or complicated, with or without SCADA. OPIR provides tailored ad platbased solutios. OPIR is part of the Aquasuite product family: itelliget solutios for advaced moitorig ad cotrol of water supply systems. OPIR cotais a adaptive demad predictio cotrol, which automatically idetifies the specific cosumptio patters of a area, ad uses these to predict the water demad accurately for the upcomig 48 hours. O the basis of the available storage capacity, OPIR determies setpoits for the water productio ad distributio flow, resultig i a much more costat flow compared to covetioal pump cotrol systems. This water demad predictio sigificatly boosts process performace because: Abormal situatios are rapidly idetified as deviatios from the predictio ad ca therefore be respoded to automatically. costat productio rate prevets turbidity peaks caused by flow variatios. costat productio rate reduces eergy cosumptio sice the pumpig rate is steadier. A costat productio rate postpoes capital ivestmets thaks to the more efficiet use of productio ad trasport facilities. Eergy costs ca be further reduced by shiftig pump operatios to low eergy-tariff hours. e Best Available Techology Improved performace, optimal water quality Reduced eergy cosumptio Reliable, stable, ad trasparet operatio Miimal operatioal effort (self-learig system) Reduced equipmet wear Reduced water losses

3 OPIR Cotrol Algorithm Beefits OPIR s several compoets together make for a powerful ad trasparet cotroller. Predictio - OPIR predicts the cosumptio of a specific supply area based o historical flow ad level data. The predictio also takes ito accout the differet types of days, such as holidays. Operatig Evelope - OPIR determies flow setpoits based o the demad predictio ad o the optimal use of the available water storage, by takig the local operatioal boudary coditios ito accout. Adjustmet - OPIR aalyses ad adjusts its predicted demad tred ad defies setpoits by comparig them with real-time data. Adaptive - OPIR is a adaptive or self-learig system, thus savig the operator from havig to moitor ad adjust parameters. OPIR Implemetatio OPIR optimizig cotrol is basically a add-o to your plat cotrol system (e.g. PLC/SCADA or DCS). Basic cotrol fuctios are implemeted i the PLC, optimized setpoits are determied by OPIR. Eergy costs ca be reduced by up to 5-10% compared to covetioal cotrol. Turbidity ca be reduced by up to 20% compared to covetioal cotrol. After a few weeks of operatio, OPIR ca predict daily water demad with a accuracy of 98-99%, ad hourly demad with a accuracy of 94-96% Predictio-based cotrol meas smooth cotrol, little variatio, little equipmet switchig (less wear), ad better overall process coditios. OPIR Refereces 70% of Dutch water compaies use OPIR. 40% of the Dutch populatio drik water cotrolled by OPIR. OPIR is also beig used by water compaies i Caada, Portugal, Polad, ad Belgium. OPIR software ca be istalled o ay type of computer, such as a ormal desktop PC, a server or a idustrial PC with a Widows operatig system. OPIR commuicates with the PLC through the cotrol etwork ad geerates web-based visualizatio with settigs, treds ad extra OPIR fuctioalities (e.g. dashboard, eergy moitor). OPIR cotrol software is built i modular fuctio blocks, which permits flexible implemetatio. Depedig o the drikig water system ad available measuremets, OPIR cotrol loops ca be cofigured i several ways. The cofiguratio is determied durig the desig phase of the project.

4 OPIR s Additioal Modules OPIR Pressure Cotrol: OPIR calculates a optimal pressure setpoit for the distributio pumps, at which all pressure coditios are satisfied. OPIR Performace Dashboard: allows for ogoig evaluatio of daily, weekly, ad curret performace, ad permits quick idetificatio of ad respose to ay abormalities. Eergy Moitor: moitors the effect of OPIR performace o eergy cosumptio. Abstractio Permits Moitor: predicts abstractio amout up to a year. This helps to prevet exceedig the maximal abstractio permit. Highly Reliably OPIR is highly reliable thaks to its predictive ature. OPIR cotais several fallback algorithms i the evet that sesors malfuctio. Eve i the absece of ay fuctioig olie measuremets, the predictio still provides itelliget cotrol for at least 24 hours. Project approach System desig: Royal HaskoigDHV ad the cliet cosult to determie how OPIR should be implemeted i a specific plat. Royal HaskoigDHV the cofigures ad tests OPIR offlie, accordig to the plat s particular circumstaces. Realizatio, testig, ad implemetatio: Modificatios to, ad programmig of, the PLC ad SCADA (or DCS) are carried out by a cotractor or the cliet (ot Royal HaskoigDHV). The cotractor programs ad tests the PLC/SCADA, istalls ad coects the OPIR computer, ad cofigures ad prepares the commuicatio with OPIR. Royal HaskoigDHV writes the specificatios for the cotractor ad, together with the cotractor, tests the PLC-OPIR iterface ad the PLC fuctioality. Start-up: To begi with, OPIR rus i the backgroud so that it ca begi learig the plat s characteristics. Royal HaskoigDHV cosultats closely moitor OPIR s performace i order to guaratee that the cotroller is well tued. After this iitial period, OPIR is put ito operatio ad the operators ca choose to switch to active OPIR cotrol. Licese, Service, ad Evaluatio Royal HaskoigDHV offers a service cotract i which the OPIR software ad licese are upgraded every cotract year through a remote coectio. As part of the stadby service, Royal HaskoigDHV egieers are available to aswer questios ad offer olie support ad troubleshootig through the remote coectio. As a optio, Royal HaskoigDHV ca also coduct a aual evaluatio of OPIR ad of the plat s performace, after which a report is prepared icludig possible recommedatios for improvemets. Operatioal Excellece Royal HaskoigDHV process ad cotrol experts are available for weekly or bi-weekly pro-active support o ruig your water supply system with OPIR. Support cosists of regularly checkig OPIR performace ad process coditios through a remote coectio, remote data aalysis, stadby service for aswerig questios ad assistig i troubleshootig. This backs up your staff o their way to operatioal excellece. Royal HaskoigDHV also offers operator traiig, icludig traiig certificates. I the evet that the OPIR system or commuicatio itself fails, process cotrol is still guarateed sice the back-up plat cotrol i the PLC (or DCS) is automatically activated. Aquasuite Aquasuite is a product family of itelliget solutios for advaced moitorig ad cotrol of water treatmet systems. Through the Aquasuite, advaced forecastig systems, model-based ad decisiosupport cotrollig software are made available i a joit effort by Royal HaskoigDHV egieers ad our cliets. Welcome to the OPIR users commuity, Welcome to iovatio! Decades of experiece, kowledge, ad best practices have bee brought together i OPIR to offer geeral solutios for water treatmet. OPIR has bee ad will cotiue to be developed as part of a combied effort of cliets, parters, ad Royal HaskoigDHV, thus offerig a perfect platform for ew, iovative cotrol solutios ad a quick route to market. This meas that every cliet profits from the experiece ad the best practices of its peers.
