Moving Bed Bioreactor (MBBR)

MBBR is a type of wastewater treatment process that was first invented by prof. Hallvard Odegaard at Norwegian university of science and technology in the late 1980’s. MBBR is the most commonly used technology for sewage treatment. It utilizes carrier media for biological growth and for biological degradation. The MBBR system consists of an activated sludge aeration system where the sludge is collected in recycled plastic carriers. These carriers have an internal large surface for optimal contact water, air and bacteria. It has compact units with small size. It can increase the capacity of the treatment. Solid waste material will be removed completely. MBBR have improved settling characteristics and operate at higher suspended biomass. It has many benefits such as, concentrations resulting in long sludge retention times, enhanced process stability, low head loss, less area required, resilient to toxic shocks, no filter channeling, no need of periodic backwashing, reduced sludge production and no problems with sludge bulking. Experiments with moving bed bioreactors have also shown that these systems achieve partial removal of organic micro-pollutants from the wastewater. These come with design, installation, service maintenance and one-year warranty. The AMC (Annual Maintenance Contract) can be renewed annually.
