Membrane Bioreactor (MBR) Solutions
Integrated Water Services
As environmental regulations become increasingly stringent, Membrane Bioreactor (MBR) Technologies enable developers to treat wastewater streams to meet even the strictest permit regulations. Membrane bioreactors for wastewater treatment offer several benefits, including:
- Treated wastewater effluent can be used in reuse applications.
- Remote facilities can be constructed in decentralized locations.
- Cost-effective in flow ranges from 7,500 GPD to 2 MGD.
- Mobile units available, allows for temporary plant bypass.
In general, membrane bioreactor systems are comprised of similar components, just scaled to match the intended flow rate of the facility. Wastewater treatment systems have:
Headworks Screen
Removes course solids such as rags, sticks, wood, and other larger materials that clog or disrupt the treatment process.
Equalization Tank
Normalizes the otherwise inconsistent flow rate of a service area.
Treatment Basin
Has zones for anoxic and anerobic processing and houses the membrane filters.
Sludge Processing
Holding tank for biological processes and dumpster for landfill.
Effluent Discharge
Chemical contact tanks, reuse storage tanks, and/or discharge pumps.
MBR plants are becoming an increasingly popular alternative, amongst private communities and municipalities alike. IWS has designed and constructed plants with all of the major membrane technologies, including flat plate, hollow fiber and ceramic membranes.

Critical Components of MBR Systems
Membrane filtration is a crucial component of wastewater treatment. MBR systems use various types of membrane filtration to ensure the highest quality of treated water.
Managing membrane fouling is critical to the operation of MBR systems. IWS employs advanced techniques to minimize fouling and extend the life of the membranes.
MBR systems often utilize submerged and ultrafiltration (UF) membranes, which enhance the efficiency and effectiveness of the treatment process.
The biological treatment processes within MBR systems, including the activated sludge process, ensure the breakdown of organic matter and the reduction of nutrient levels in the treated water.
Nutrient removal is a vital function of MBR systems, achieved through specialized membrane modules. This ensures compliance with environmental standards and the production of high-quality effluent.
MBR systems produce high-quality treated water suitable for various water reuse applications, contributing to sustainable water management practices.
Regular chemical cleaning of the membrane material helps maintain the efficiency of MBR systems and ensures long-term performance.
MBR systems are also used to treat landfill leachate and manage biomass effectively to ensure environmentally safe discharge.
Microorganisms’ role in MBR systems is crucial for the solids concentration and overall effectiveness of the wastewater treatment process.
