Xylem’s Wedeco LBX 850e and LBX 1500e ultraviolet (UV) disinfection systems have received acceptance from the California State Water Resources Control Board’s Division of Drinking Water. These closed-vessel UV systems are now validated and approved for unrestricted reuse applications to meet the stringent water disinfection standards as required by Title 22 of the California Code of Regulations.
The acceptance of the LBX 850e and 1500e UV systems adds to the existing portfolio of Wedeco UV systems approved for Title 22 reuse applications including the LBX 90e, LBX 400e and LBX 1000e along with the open-channel TAK55 and recently approved open-channel Duron, the first Title 22 reuse approved disinfection system with an inclined lamp array.
Xylem’s Wedeco LBX system is designed for medium to large-scale wastewater treatment plants, industrial and water reuse applications and is a closed-vessel UV system for wastewater disinfection. It was the first closed-vessel, low pressure, high output amalgam UV system in the world to obtain California Title 22 acceptance, Xylem said. The system features Ecoray lamp technology which consumes approximately one-third of the energy of medium pressure lamps, the company said.
Wedeco UV disinfection systems are currently being operated for Title 22 water reuse applications in California at the Silicon Valley Advanced Water Purification Center in San Jose. “The approval by the State means that Xylem’s Wedeco brand can provide its customers in California and beyond with one of the broadest portfolios of approved UV disinfection systems for water reuse of any manufacturer,” said Richard Loeffler, Wedeco senior sales engineer for Xylem.
