Abstract: A method, system, and computer readable storage medium for determining an optimal amount of coagulant to be added to water for coagulation treatment. The method includes predicting a water quality index that would be achieved for a corresponding nominal coagulant dose by evaluating at least one coagulation-related incoming water parameter of water that has not been treated with coagulant, with a first mathematical model constructed from historical data including (i) previously administered coagulant dosages; and (ii) previously determined values of the water quality index of the water. The method also includes determining whether the predicted water quality index is within a target range. If the predicted quality index is not within the target range, then the coagulant dosage can be adjusted, and the adjusted dosage can be evaluated to predict the water quality index that would be achieved if the adjusted coagulant dosage is administered to the water.
