Xylem to supply UV disinfection solutions to two water plants in Ohio, US

Global water technology company Xylem has secured contracts for the supply of ultraviolet (UV) disinfection solutions to two major drinking water plants in the City of Columbus, Ohio, US.

Under the terms of the contracts worth $4.8m, the company will supply the energy-efficient UV technologies, which will be used to provide an additional treatment barrier for chlorine-resistant parasite Cryptosporidium at the Dublin Road Water Plant (80 MGD plant) and Hap Cremean Water Plant (125 MGD plant).

Cryptosporidium, which can be spread by swallowing contaminated water, can cause illness with potentially severe symptoms.

Xylem supplied 24 Spektron 2000e UV reactors for the Hap Cremean Water Plant and five Wedeco K143 UV reactors for the Dublin Road Water Plant.

Xylem North America director of treatment sales Greg Claffey said: “Our proven Wedeco UV technology was selected because it delivered the lowest life-cycle cost, primarily due to the energy efficiency of its low-pressure high-output (LPHO) Wedeco Ecoray lamps and the relative low head loss of the UV reactors.

“Furthermore, we were able to overcome the challenging requirements associated with the Hap Cremean plant retrofit.”

Construction at both the plants is anticipated to begin next year and their UV systems are expected to be operational in 2020.

With its October 2016 acquisition of Sensus, Xylem added smart metering, network technologies and advanced data analytics for water, gas and electric utilities to its portfolio of solutions.
