Moving Bed Bioreactor

MAK Water’s Moving Bed Bioreactor (MBBR) type packaged sewage treatment plants are designed to treat domestic strength sewage, to achieve “Class C” treated effluent, suitable for reuse in “risk category low” applications or for discharge to environment. With the optional “Class A” upgrade, treated effluent suitable for reuse in “risk category medium” applications is achieved.

The standard treatment process includes influent screening, balance tank mixing, anoxic & aerobic treatment, clarification, effluent sterilization (chlorine tablets) and bag filtration (100 micron). The optional “Class A” upgrade includes an auto-backwashing aseptic glass media filter (5 micron), secondary chlorination via tank recirculation and residual trim hypochlorite dosing, and analyzers for online monitoring of treated effluent turbidity, free chlorine and pH.

MAK Water’s MBBR 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.

If you have specific requirements, contact us to discuss our custom designed sewage treatment plants or ask about our hire options.
