This article presents a new computer modeling program that analyzes real‐time water chemistry to help operators predict more accurately the required coagulant changes when time is limited. The article discusses how the model was used at the Grand Rapids Lake Michigan Filtration Plant, how it was linked to the plant's supervisory control and data acquisition (SCADA) system so the coagulant‐dose computer program would receive real‐time data, the two coagulation methods of charge neutralization and sweep coagulation, and using UV254 to detect organics.
