For power generation facilities using reclaimed water, controlling chlorine before RO filtration is a balancing act: too much chlorine can damage membranes and downstream EDI systems, while too much sodium bisulfite can contribute to biofouling and unnecessary chemical spend. In a California power station trial, the Hach ULR CL17sc Chlorine Analyzer helped operators move beyond grab sample monitoring and improve visibility into chlorine residual after SBS addition. Once readings were connected to the plant’s DCS, operators were able to tighten process control, reduce chlorine excursions, and make more informed dechlorination decisions. The result: ✔ More than 30% reduction in SBS usage ✔ CIP cycles cut in half ✔ Better membrane biofouling control ✔ Added protection for RO, EDI, and steam generation processes For facilities where downtime, chemical usage, and membrane replacement costs add up quickly, real-time chlorine monitoring can support both process optimization and risk reduction. Learn how improved chlorine residual control can help protect critical water treatment assets. #WaterTreatment #PowerGeneration #ROFiltration #ChlorineMonitoring #ProcessOptimization #Hach
