6 Plants are operated by WEHRLE-Umwelt GmbH in Germany Realised plant operation models in Germany for landfill leachate treatment. BOT, BOO; BTO Some plants are operated since 1995 by WEHRLE Umwelt GmbH. 6

7 Plants are operated by WEHRLE-Environmental in the United Kingdom Kelloggs Realised plant Operation since 2007 models in the United Kingdom. There are tow industrial plants and one landfill leachate treatment plant under operation of WEHREL Environment. Foston Beacon Hill 7

8 Plants are operated by TELWEAS in Spain Since 2004 GBI Serveis S.A. & WEHRLE Umwelt GmbH established TELWESA to operate wastewater treatment plants 8

9 Plant management under supervision of WEHRLE Umwelt GmbH The first landfill leachate treatment plant in Slovenia will be operated by WEHRLE Umwelt GmbH. Commissioning will be in March

10 Feasibility Tests in our Laboratory Pre tests of inherent biodegradability of any kind of waste water Using a Laboratory Membrane Bio Reactor The pre test are the basic for further semi technical tests at the client site Generate of Isotherms from Activated carbon Detect the best specific activated carbon for the individual application The pre test are the basic for long terms activated carbon delivery contracts

11 Feasibility Tests in our Laboratory Testing of different Nanofiltration- and Reverse Osmosis membranes Detect the concentration factor Detect the water conversion factor Detect the backing of the membranes Detect the specific Flux Ascertain the specific cleaning procedure for the membranes In the laboratory the detected parameters are the basic to scale up the membrane plant for the specific task.
