What is a moving bed biofilm reactor?
A moving bed biofilm reactor (MBBR) is the ideal sewage treatment plant for commercial, community, institutional and industrial wastewater treatment projects with continuous fluctuations in flow and strength.
Our compact, Rewatec glass reinforced plastic MBBR systems manage domestic and high organic loads in all seasons.
- caravan parks
- service stations
- pubs and restaurants
- hotels and inns
- commercial developments
- residential developments
- industrial applications
- projects where space is limited
Moving bed biofilm reactor MBBR technology
Primary treatment tank or fine screen
In typical installations, wastewater first flows into a primary treatment tank that allows liquids to separate from solids. Primary sludge that settles on the bottom of the tank requires removal by a licensed waste carrier as and when required.
In some systems, a fine screen is used instead of a primary treatment tank. This simple barrier removes wastewater solids before they can move downstream.
Equalisation tank (if needed)
After primary treatment, liquids move downstream and enter an equalisation tank. This tank collects wastewater from daily peak-use periods and then sends controlled doses to the Rewatec MBBR.
Inside the Rewatec MBBR, micro-organisms grow on floating biofilm media. They feed on organic wastewater pollutants, producing effluent composed of biomass particles and treated wastewater.
Our plastic biofilm media are specially shaped to increase the surface area on which micro-organisms grow. This maximises their ability to treat wastewater whilst also reducing the overall footprint of the sewage treatment system.
Bubbles continuously mix the contents of the Rewatec MBBR to ensure optimal contact between wastewater and micro-organisms. Again, this improves their ability to remove wastewater pollutants.
Clarification tank and final discharge
After treatment in the Rewatec MBBR, wastewater flows into a clarification tank, where liquids are separated from biomass.
Sludge is sent back to the primary treatment tank or a sludge storage tank. Liquids are sent downstream for additional treatment or for safe discharge into the environment.
