Bureau pilot tests show MBR reclamation potential

Membrane bioreactor (MBR) is a proven technology for wastewater reclamation that combines biological treatment with membrane filtration to achieve high quality effluent. Montgomery Watson Harza (MWH) and the city of San Diego have been conducting research on the MBR process since 1997 through various research projects. This article is derived from the report entitled Evaluation of Newly Developed Membrane Bioreactor Systems for Water Reclamation released in February 2009 by the US Bureau of Reclamation. The evaluation, carried out by MWH, looked at four MBR pilot systems operated for a target period of about 3,500 hours on raw wastewater from Point Loma wastewater treatment plant in San Diego, California. In addition, a reverse-osmosis desalination membrane was also evaluated while operating on MBR effluent. This article appeared in the May/June issue of D&WR magazine.
