Delivering greater effluent and productivity, while reducing lifecycle cost with MBR technology

For more than tow decades, WEBSTER® has led the membrane industry.  Since 1999, we have dedicated a team strictly to Membrane Bioreactor (MBR). Today, our technology operates in more than 200 municipal and industrial plants across the globe.

Proven to deliver greater effluent and productivity, while reducing the lifecycle cost, MBR technology is preferred by the market. Our technology uses a fully automated process that provides liquid/solid separation by combining biological waste oxidation and membrane separation. In turn, this eliminates the need for any secondary clarification or tertiary filtration.

The WEBSTER® MBR system delivers greater stability of the membrane environment, operational flexibility, and reduced maintenance requirements, resulting in significant cost savings. The system is successfully operating in applications ranging from municipal wastewater plants to the most difficult industrial applications such as oil refineries and landfill leachate.

MBR systems are for the treatment or reuse of a variety of wastewaters

Today, most MBR applications are for the treatment or reuse of municipal wastewaters. MBR systems may be applied to a variety of wastewaters from the cosmetics, pharmaceuticals, textile, food and beverage, pulp and paper, and chemical industries, as well as blackwater, greywater, and landfill leachate.

MBR systems combine a biological process and a low-pressure membrane filtration process, so expert knowledge in both areas is essential. The biological portion of an MBR is largely similar to activated sludge process commonly used in treating municipal and industrial wastewaters. With the design primarily for removing dissolved and suspended organic matter from the wastewater, the method requires that an assortment of microorganisms be present in the same reactor.

A major consideration in selecting membranes for MBRs is the need to minimize fouling. This is dependent on feedwater quality and aspects of the system design such as: membrane material, module dimensions, flux, and conditions at the membrane interface. Advanced fouling control today typically uses random large bubble air scouring combined with mixed liquor pumping to provide a low energy, low fouling MBR system.
