Abstract:

The San Jose/Santa Clara Water Pollution Control Plant (“Plant”) is an advanced wastewater treatment facility with a rated capacity of 167 MGD. Over the past year it implemented three major energy savings projects: optimization of pump station operation, optimization of operation of the dissolved air floatation system and replacing continuous aeration of mixed liquor channels and anaerobic/ anoxic compartments of the BNR process with pulsed (intermittent) aeration (Patent pending). Estimated energy savings is 1.3 million dollars. Cost of the projects was less than 300,000. Project cost was refunded to the Plant by the Electrical Utility.
