UV Installed to Deactivate Chlorine Tolerant Organisms, Advancements in Drinking Water Disinfection

Project: City of Berea, Ohio, Drinking Water


The Challenge

The City of Berea mandates the best possible water quality for its residents and had been closely monitoring the quality of the water source. In 2008, Cryptosporidium was detected in 10 of the 24 samples collected from the East Branch of the Rocky River.

The Solution

This emerging threat to public health is effectively deactivated using UV, and has now become an important barrier both in the U.S. and globally to ensure that drinking water is healthy and free from any harmful organisms. Nationwide, UV systems are being installed into municipal drinking water facilities to deactivate Cryptosporidium and Giardia, both organisms that are tolerant to chlorine. Two ETS SX-425-10 validated systems were installed. Typically, a duty and standby arrangement is required to ensure that an adequate level of treatment is always achieved.
