Membrane Bioreactor

MAK Water’s Membrane Bioreactor (MBR) type packaged sewage treatment plants are designed to treat domestic strength sewage, to achieve “Class A+” treated effluent, suitable for reuse in “risk category high” applications or for discharge to sensitive environments.

The standard treatment process includes influent screening, balance tank mixing, anoxic & aerobic treatment, ultrafiltration (UF) with automated chemical cleaning system, effluent sterilization via UV and/or tank recirculation and residual trim hypochlorite dosing, and analysers for online monitoring of treated effluent turbidity, free chlorine and pH. Additional treatment steps for nutrient removal (T-N & T-P) and sludge de-watering systems may be added as required to suit influent quality and/or treated effluent quality requirements.

MAK Water’s MBR Bioreactors are constructed of corrosion resistant FRP, and are self-contained, modular systems for easy deployment to remote locations.

The FRP bioreactor tank fits into a 40’ shipping container. This allows it to travel as general purpose cargo on a conventional container vessel, for cost effective shipping anywhere in the world, as well as providing mechanical protection from damage during shipment.
