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. 10 10
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.
