Xylem has won approval for two ultraviolet disinfection systems from the drinking water division of California’s water resources control board.

Wedeco LBX 850e and LBX 1500e ultraviolet disaffection systems are now approved for unrestricted water reuse applications. “The approval means that Xylem’s Wedeco brand can provide its customers in California and beyond with one of the broadest portfolios of approved ultraviolet disinfection systems for water reuse of any manufacturer,” said Xylem senior sales engineer, Richard Loeffler.

Ultraviolet disinfection is increasingly being used in water reuse systems in place of chemical-based disinfection. A survey of California residents by Xylem in 2016 found that 76 per cent of respondents see recycled water as a long-term solution for managing water resources, and 89 per cent were more willing to use recycled water after learning more about the treatment processes involved.

The two closed-vessel UV systems are now validated and approved to meet the stringent water disinfectant standards of Title 22 of the California Code of Regulations.
