MBR Systems

In recent years, MBR plants using low-pressure submerged membranes have become more cost effective and the state of the art technology for treating wastewater. The combination of an activated sludge process and membrane technology removes carbon, phosphorous, nitrogen, certain toxins (carcinogenic, mutagenous, and hormonally active) and bio-accumulative micro-contaminants.

In the 21st century, declining fresh water resources and tightening municipal and industrial wastewater treatment plant effluent regulations require improved water and wastewater treatment methods. A significant portion of the United States has adopted stricter wastewater effluent regulations and the remaining areas are soon to follow. In many cases the effluent quality leaving wastewater treatment plants influences the quality of local ground water and drinking water. Today almost 90% of Americans have some concerns about the quality of their household drinking water. Consequently, authorities, industries, and developers seek alternatives to treat water, wastewater, and process water.

Pre- and Post-Treatment

Pollutants that cannot be eliminated by a membrane bioreactor can be eliminated by post-treatment such as nanofiltration or reverse osmosis.

Selective Barrier

The primary role of the membrane is to act as a selective barrier to eliminate fine particles up to dissolved matter from water and wastewater.
