Patented treatment process for water reuse and river water to produce demineralized and ultrapure water

Reverse osmosis is a key process for the treatment of river water and for industrial water reuse applications. Even low concentrations of biodegradable organic substances can lead to the formation of biofilms on the membrane surfaces. This significantly impairs the performance of the system and leads to increased operating costs due to rising pressure losses and more frequent cleaning processes.

To avoid these problems, the BiosS-Treat system relies on pre-treatment through precipitation and biologically active filtration. This effectively removes biofilm-promoting substances - and enables permanently stable, economical operation of the downstream reverse osmosis system, even with challenging surface water or wastewater.
