ITT has developed an innovative dual-stage membrane bioreactor (MBR) for advanced treatment of industrial wastewater that delivers a higher quality effluent in less space and with lower operating costs than are normally associated with conventional activated sludge processing system.

Targeted at industrial wastewater applications, the ITT Dual-Stage MBR system is a complete and continuous process. It accepts wastewater with high loadings of BOD, suspended solids and other contaminants and yields an excellent quality effluent that can be suitable for direct discharge to surface water bodies (depending on local regulations) and "low grade" re-use applications such as vehicle washing. The water can be further treated with polishing processes (for instance, reverse osmosis) to yield potable water.

Applications for MBR include:

• Food & beverage production
• Chemical and pharmaceutical manufacturing
• Pulp and paper processing
• Metal finishing
• Steel production
