UV₂₅₄ and Streaming Current Monitors can Improve Coagulation Control in Challenging Conditions

Abstract

Heavy rains and spring snowmelt can cause turbidity and natural organic matter spikes in influent source water, curtailing optimal coagulant performance. During periods of rapid decline in source water quality, when conditions outpace time‐consuming jar testing, online process control loops show promise for finding and keeping the right coagulant dose.
