Moving Bed Bioreactor Plus
MAK Water’s Moving Bed Bioreactor Plus (MBBR+) type packaged sewage treatment plants are designed to treat domestic strength sewage, to achieve “Class C” treated effluent, plus enhanced nutrient removal, 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 for nitrification and denitrification, 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 corrosion resistant , and are self-contained, modular systems for easy deployment to remote locations.
