What is a membrane bioreactor?
A membrane bioreactor (MBR) is a compact, highly effective solution for commercial and municipal wastewater treatment projects near ecologically sensitive areas.
Suitable for flows of up to 1 mgd, Rewatec MBR systems use a unique ultrafiltration membrane to block fecal coliforms and other wastewater pathogens.
The membrane has pores that are just 0.4 µm wide, making it so effective that treated effluent can be reused for non-potable applications (where allowed).
Where are our MBR systems used?
Rewatec MBR systems are most often solutions for:
- residential developments
- municipal developments
- schools
- campgrounds and parks
- roadside rest areas
- work camps
- sites near ecologically sensitive areas
- installations with faulty membranes
How do our MBR systems work?
Primary treatment tank or fine screen
In typical installations, wastewater enters a primary treatment tank that allows liquids to separate from solids. Primary solids settle on the bottom of the tank and are removed by a septic pumper as often as needed.
Liquids pass through an integrated effluent filter before leaving the primary treatment tank. The filter captures suspended solids that could clog system components downstream.
Sometimes a fine screen takes the place of the primary treatment tank, acting as a simple physical barrier to remove solids from wastewater.
Equalization tank (if needed)
After primary treatment, liquids move downstream into an equalization tank. This tank collects wastewater from daily peak-use periods and sends controlled doses to the Rewatec MBR.
Rewatec MBR and final discharge
The Rewatec MBR combines two treatment processes in one tank to produce effluent that meets the most stringent standards.
In the first step, aeration cycles provide oxygen to microorganisms that feed on organic pollutants. As microorganisms increase in number, they mix with other solids to form activated sludge – the biomass that treats incoming wastewater.
Biomass remains in the tank, eventually reaching concentrations up to three times higher than those found in traditional activated sludge systems. This key feature minimizes the size of the installation, making Rewatec MBR systems the most compact solutions available.
In the second step, a low-pressure vacuum sucks wastewater through the pores of a rigid ultrafiltration membrane that blocks even the most persistent pollutants. Clarified wastewater is then pumped out of the tank and safely discharged into the environment.
The fine bubbles that aerate the biological process are also used to scour the membrane, preventing surface clogging and getting maximum value for all energy consumed.
