De Nora to install ClorTec sodium hypochlorite generator at Arizona water treatment plant

De Nora is set to install a ClorTec sodium hypochlorite generator system to boost the on-site sodium hypochlorite generation (OSHG) capacity of the Santan Vista Water Treatment Plant in Gilbert, Arizona.

Currently, this facility uses two ClorTec units to provide quality drinking water to more than 100,000 residents of Gilbert town and Chandler city.

Utilising common consumables of salt, water, and electricity, ClorTec OSHG systems generate a 0.8% sodium hypochlorite disinfection solution, which is a chlorine equivalent.

Mike Schlabach of Sundt Construction, installer of the ClorTec systems, said: “The decision to use the De Nora ClorTec generator train to expand the Santan Vista Water Treatment Plant to keep up with the local population growth was a simple one.

“The plant operators have been pleased with the system’s performance since its initial implementation, Sundt has extensive experience installing the components, and the value proposition offered through De Nora was significant.”

Claimed to be a cost-effective, reliable, and safe alternative disinfection treatment method, with consistent chlorine concentration and residual in the treated water, ClorTec OSHG system can not only reduce a customer's carbon footprint and salt consumption by around 20% but also the production of disinfection byproducts.

ClorTec systems are designed to meet any required application, with units in capacity ranging from 2.7 kg per day to over 1,360 kg per day.

To meet different applications, the ClorTec units come as component-based or skid-based packaged systems.
