Key highlights
- Kemira completed a one-month full-scale KemConnect DEX trial with Capital Region Water in Harrisburg, PA.
- The milestone occurred eight months after the DEX core ingredient was registered with the EPA.
- The performic acid–based treatment rapidly reduced bacterial counts at low doses and auto-degraded into readily biodegradable compounds.
- DEX automates dosing with real-time data, offering flexible feed rates and on-site installation to avoid large capital costs of chlorine or UV alternatives.
Trial overview
Kemira completed a one-month full-scale trial of its chlorine-free KemConnect DEX wastewater treatment system at Capital Region Water’s Harrisburg, PA facility.
Timing and regulatory
The trial took place eight months after the DEX core ingredient—performic acid—was registered with the US EPA for commercial use.
Treatment performance
At low doses, the performic acid–based solution rapidly reduced bacterial counts and auto-degraded into readily biodegradable compounds with low environmental persistence.
Operational features
DEX automates dosing using real-time data and flexible feed-rate control, enabling consistent bacterial control despite weather-driven fluctuations in flow and water quality and supporting on-site installation to avoid the capital costs of many chlorine-based or UV alternatives.
