Trojan Technologies has succeeded in efforts to gain regulatory approvals for its UV treatment technology for treating wastewater for non-potable use in California.
After the completion of third-party validation testing under the U.S.National Water Research Institute (NWRI) Guidelines, the technology has received conditional acceptance from the California Water Board’s Division of Drinking Water (DDW) Recycled Water Unit (RWU).
Developed in London, Ont., the TrojanUVSigna technology is the first and only 1000-watt low-pressure, high-output-based UV system to obtain acceptance from the DDW RWU, and meet the strict coliform and virus disinfection criteria found in Title 22 of the California Code of Regulations for recycled waters.
“The reuse of wastewater treated to very stringent levels for non-potable applications continues to gain widespread support, and is being adopted by municipalities throughout the world as a means of achieving a sustainable water supply,” said Wayne Lem, market manager, Trojan Technologies.
“This Title 22 approval is an important milestone for us, and it now gives municipalities in California the option to confidently choose a compact, cost-effective UV system for their wastewater reuse projects.”
The TrojanUVSigna has also received third-party approval for lamp age testing and cleaning system effectiveness per NWRI guidelines.
The City of Jackson, California has plans to install it at its wastewater treatment plant in Amador County. The Jackson plant will disinfect four million gallons of wastewater per day and will play an important role in ensuring effluent entering Jackson Creek and Lake Amador meets applicable standards. In 2015, the city commissioned a report that recommended upgrades to meet regulations regarding water quality of discharge to the creek.
