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, aerobic treatment, clarification and effluent disinfection (chlorine tablets). The optional “Class A” upgrade includes an auto-backwashing glass media filter, secondary chlorination via tank recirculation and residual trim hypochlorite dosing, and analysers 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.
If you have specific requirements, contact us to discuss our custom designed sewage treatment plants or ask about our hire options.
