Kemira, one of the global leaders in sustainable chemical solutions for water-intensive industries, announced that it has successfully completed the first US full-scale trial of its chlorine-free wastewater treatment technology, KemConnect®DEX, with Capital Region Water, the advanced wastewater treatment facility serving the city of Harrisburg, Pennsylvania and surrounding municipalities. This milestone was achieved in just eight months after the core ingredient of DEX was registered with the Environmental Protection Agency (EPA) for commercial use in the US.

The KemConnect DEX solution is uniquely based on performic acid, a fast-acting, sustainable alternative to traditional chlorine-based microbial control. Results from the one-month full-scale trial demonstrate that even at low doses, Kemira’s performic acid-based solution quickly reduces bacteria levels and rapidly auto-degrades into readily biodegradable compounds, which exhibit low environmental persistence- thereby improving water quality, while minimising environmental impact.

The technology behind KemConnect DEX automates treatment dosing based on real-time data, with flexible feed-rate capabilities that enable operators to consistently meet required bacterial limits despite weather-driven fluctuations in flow and water quality. The DEX technology platform is also installed on-site, enabling facilities to modernise their infrastructure without the considerable costs and investment often required by many chlorine-based solutions and UV treatment alternatives.
