South Bay Water Recycling (SBWR) is a program of the San Jose/Santa Clara Water Pollution Control Plant (Plant) that supplies recycled water for landscape irrigation and industrial use to three cities in the Silicon Valley area of northern California. SBWR began full-scale operation in 1998 and now supplies over 10 mgd of recycled water during the summer months to more than 400 customers. Concentration of total dissolved solids (TDS) currently ranges between 770 and 820 mg/L such that the water is suitable for all current uses. However, the TDS will likely increase as recycled water is used more extensively for evaporative cooling to the point that it may no longer be suitable for irrigation of some salt-sensitive plants and the cost of pretreatment for industrial use will increase.

The United States Bureau of Reclamation awarded the City of San Jose a research grant to investigate the feasibility of using advanced water treatment to create high purity water from recycled water for industrial use. Microfiltration followed by reverse osmosis (MF/RO) and electrodialysis reversal (EDR) were selected to reduce the salinity Plant's effluent (tertiary treated wastewater) from a concentration of approximately 800 mg/L TDS to 500 mg/L (38 percent reduction) and 350 mg/L (56 percent reduction).

Field-scale demonstration plants were used to determine: (1) process efficiency at the manufacturer's recommended operational parameters, (2) impacts of pretreatment – MF (PP & PVdF), media filters, no pretreatment, and (3) optimum parameters consistent with achievement of water quality goals.
