en.Wedoany.com Reported - Finnish chemical company Kemira has successfully completed the first full-scale trial of its chlorine-free wastewater treatment technology, KemConnect DEX, at the Capital Region Water facility in Harrisburg, Pennsylvania, USA. This one-month test confirmed the technology's effectiveness and environmental advantages in practical application.

The trial results show that the peroxyformic acid-based solution used in the KemConnect DEX system can significantly reduce bacterial content in wastewater at low doses while minimizing environmental impact. Compared to traditional chlorine-based disinfection methods, this technology rapidly decomposes into biodegradable substances, thereby reducing the persistence of residual chemicals in treated water.

This advancement builds upon the core peroxyformic acid ingredient receiving commercial use registration from the U.S. Environmental Protection Agency. Kemira completed this full-scale trial within eight months of receiving approval.

Capital Region Water, the water supply agency for Harrisburg and surrounding areas, collaborated with Kemira to implement this technology. The agency reported that the trial validated the feasibility of using a chlorine-free method to replace traditional chlorine disinfection for microbial control, offering a more sustainable solution for wastewater treatment.

The KemConnect DEX platform combines peroxyformic acid chemical treatment with an automated dosing system based on real-time monitoring data. The system can automatically adjust dosing rates based on factors such as flow variations, water quality fluctuations, and weather events, ensuring stable bacterial control under different conditions.

The technology features a modular design, facilitating on-site installation and integration. This allows wastewater treatment facilities to upgrade their treatment processes without the high capital expenditures typically required for traditional chlorine-based or ultraviolet disinfection systems.

As environmental regulations become increasingly stringent and the demand for sustainable operations grows, Kemira states that this successful trial will promote the broader adoption of chlorine-free wastewater treatment technology in the United States and globally, providing the water industry with more environmentally friendly and economical disinfection options.
