Quality objective

 

High-quality treated water

The water quality obtained after Biosep™ is fully in compliance with stringent environmental standards and meets as well municipal and industrial needs.
Biosep™ achieves high removal of carbon and nitrogen pollution and retains almost all of the suspended matter. At the same time, the water disinfection is performed through the membrane filtration step.
Biosep™ can be adapted to loading variations whilst ensuring consistent treated water quality.

Efficient treatment of municipal and industrial effluents:
