Operating principle of the Evac MBR, membrane bioreactor
All Evac MBR plants work in the same way, using proven, very low maintenance membrane bioreactor technology that is capable of filtering out particles as small as bacteria.
The treatment process consists of three phases:
- The biological process
- Membrane filtration
Clean water is separated from the biomass using membrane filtration with submerged flat-sheet membranes. The pressure difference for the membrane filtration is only around 30 mbar – such a small amount of pressure guarantees the membranes an extremely long life. The treated water does not need any further disinfection and can be discharged directly into the sea.
The Evac MBR does not require any back-flushing or constant chemical cleaning, making it the most economical and maintenance-friendly membrane solution available today. The effluent quality is so good that it can be reused.
