US Facility Successfully Tests Chlorine-Free Wastewater Treatment
The trial in Pennsylvania demonstrates performic acid as a sustainable and efficient alternative to traditional chemical disinfection.
Kemira has finished the first full-scale U.S. trial of its chlorine-free wastewater treatment technology, KemConnect DEX, at a Pennsylvania treatment facility.
The month-long trial was conducted alongside Capital Region Water, which serves the Harrisburg area. The technology uses performic acid, a sustainable microbial control agent that serves as an alternative to traditional chlorine-based methods.
Data from the trial indicated the solution effectively reduced bacteria levels at low doses. Unlike chlorine, the performic acid solution auto-degrades into biodegradable compounds, reducing the environmental footprint and persistence of chemicals in the local water supply.
The system utilizes a digital platform to automate chemical dosing based on real-time data. This allows plant operators to maintain bacterial limits even when weather events cause sudden fluctuations in water flow or quality.
Because the platform is installed on-site, it allows existing facilities to modernize infrastructure without the significant capital investment typically required for ultraviolet treatment or large-scale chlorine system overhauls.
The trial comes eight months after the EPA registered the core ingredient of the technology for commercial use in the United States.
