Crossflow MBR

Cross flow membrane systems

The MemTriq® is based on a cross-flow filtration process.

The biomass is filtered in a filter installation next to the bioreactor. The membrane modules are placed in a pressurized circulation loop located outside the bioreactor. Membrane fouling is prevented by the use of the shear forces created by the cross-flow operation of the membranes.

Prerequisites for the application of cross-flow Membrane Bioreactors:
•    Concentrated wastewater 
•    Waste water that is not easily biodegradable 
•    Small pore sizes 
•    Lower flows (< 20m3/h)
