Hypochlorite generation uses salt, water, and electricity to generate a dilute bleach solution on- site, eliminating the storage, transport, and regulatory issues of chlorine gas. It also (usually) costs less than bulk-delivered hypochlorite. The disinfection technology’s been in use since at least the early 2000s, and cut down expenses for an award-winning Florida water utility.

This application is unique because tertiary effluent produced by the district’s Water Reclamation Facility will feed the system after reverse osmosis (RO) pretreatment. The district chose Process Solutions Inc.’s MicrOclor MC-200 generator with a capacity of 200 pounds per day of free available chlorine (FAC) and a peak flow rate of 5,200 gallons per minute (gpm).
The RO system is also from Process Solutions.
The district’s gradually been replacing all gas chlorine disinfection with the MicrOclor generators. “We’ve continued to use them because of their high quality backed up by exceptional field service and warranties,” says Associate Engineer Jacob Wiley.
RCWD serves 120,000 people in the City of Temecula, along with portions of the City of Murrieta and the unincorporated regions of southwest Riverside County. The service area includes 940 miles of water mains,Vail Lake Reservoir, and 47 groundwater wells. The district also imports water from northern California and the Colorado River.
