CA water reclamation plant to install groundbreaking water reuse technology

June 3, 2015
Xylem has been commissioned to deliver its Wedeco MiPRO photo Advanced Oxidation Process, a unique water reuse solution, to help increase the supply of purified, recycled water in the city of Los Angeles, Calif.

LOS ANGELES, CA, June 3, 2015 -- Xylem, a global water technology company, recently announced that it has been commissioned to deliver a unique water reuse solution to help increase the supply of purified, recycled water in the city of Los Angeles, Calif. The company's Wedeco MiPRO photo Advanced Oxidation Process (AOP) will ensure that the city's Terminal Island Water Reclamation Plant complies with California's stringent groundwater recharge regulations for indirect potable reuse (IPR) in the safest and most cost-effective way possible.

Xylems Wedeco MiPRO photo AOP solution will be installed as a final barrier against pathogens and contaminants that cannot be removed by other technologies. The system is part of an expansion of the plant at the Advanced Water Purification Facility, which includes microfiltration and reverse osmosis prior to AOP. The customized solution, validated through extensive pilot-scale testing at the plant, will be the first greenfield AOP design using ultraviolet (UV) light with chlorine for IPR.

The Terminal facility treats wastewater from more than 100 businesses in the heavily industrialized Los Angeles harbor area and from 130,000 residents, including the communities of Wilmington, San Pedro, and a portion of Harbor City. The plant purifies tertiary effluent, producing potable water quality for recharging the stressed drinking water aquifers. The recycled water will be used as a barrier against seawater intrusion to protect the groundwater against increased salinity, as well as a supply to local industries.

Los Angeles Sanitation is the owner and operator of the Terminal plant that will provide 12 million gallons per day of highly purified water for beneficial use to reduce dependency on imported potable water supplies. Construction for the second-phase expansion will begin in 2015 with operation expected to commence in 2017.

Additionally, Xylem will be supplying a Sanitaire aeration system to the facility for enhancing the performance of the existing wastewater biological treatment system. The Sanitaire fine bubble aeration grids will consist of Silver Series II membrane disc diffusers and ceramic disc diffusers to enhance oxygen transfer, reduce energy costs and improve the quality of the water feeding the Advanced Water Purification Facility. The company has now provided fine bubble diffused aeration to all the Los Angeles Sanitation's wastewater treatment plants.
