Optimal Coagulant Dosage Control Of Raw Water

The following describes how combining of the latest data management and process management solutions can optimize the coagulation process. Coagulation is influenced by several raw water parameters. This new approach uses a feedforward model with machine learning of several raw water parameters for optimal coagulant dosage control. In addition, feed-back control can be used to trim the feed-forward model. In 2020, utilities that have installed the coagulation optimization system have achieved approximately 10% reduction in coagulant dosage while achieving similar settled turbidity.
