MBR (Membrane Bioreactor) is a combination of two basic processes – biological degradation and membrane separation – into a single process where suspended solids and microorganisms responsible for degradation are separated from the treated water by membrane filtration units.
So, in addition to removing biodegradable organics, suspended solids, and inorganic nutrients, MBRs retain particulate and slow-growing organisms and remove a very high percentage of pathogens. They also require less space than traditional activated sludge systems because of less hydraulic residence time.		Membrane Bioreactor 2D diagram
Membrane bioreactor systems may be used in applications such as water reuse. With the limited supply of water to support communities and industries, the increased cost of water and wastewater treatment and stricter environmental regulations the MBR process is a viable solution for current and future wastewater treatment.

UNIQUE Features

Capable of simultaneously biological treating and bacterial removal from the effluent;
Reduces biologically degradable solids and also inorganic nutrients (such as nitrogen and phosphorous);
Retain particulate and microorganisms (thereby intensifying treatment efficiency);
Remove a very high percentage of pathogens (thereby reducing chemical disinfection requirements);
Require less space than traditional activated sludge systems because less hydraulic residence time (HRT) is needed to achieve a given solids retention time (SRT);
Produces high quality treated wastewater for agricultural industrial and municipal uses.
