Reduction of Chloride to Wastewater Treatment Plants
Chloride is a significant threat to freshwater ecosystems, and as such is addressed in wastewater discharge regulations. Chloride cannot be removed using standard wastewater treatment technology; therefore, chloride that arrives in wastewater passes through treatment plants and enters natural water bodies as treated effluent. The main goal of this project was to determine if reducing…

Reduction of Chloride to Wastewater Treatment Plants
The final report of this study is available on Madison Metropolitan Sewerage District’s (MMSD) website. The study can be used as a model approach in areas struggling with chloride discharge. The final conclusions were that on average, softener optimizations could reduce the concentration of chlorides by 27% while replacement with systems meeting 4,000 grains/lb. salt efficiency could reduce the…

Chloramine Fact Sheet
Many municipal water supplies have switched from chlorine to an alternative method of disinfection to reduce the formation of trihalomethanes (THMs). Chloramine, or chloramination, is a treatment method employed by public water systems, more than one in five Americans uses drinking water treated with chloramines. Chloramines do pose a risk for hemodialysis patients and fish. Nitrosamines can…
