Domestic quality standards for supply water have become more stringent recently. To comply with these standards, water treatment facilities inject multiple chemicals. While most of them are expensive, they tend to overdose them to pass the criteria by using proportional dosing control in most cases.
The chemical optimal dosing control system has prediction and control functions. With the prediction function, the dosing effect of multiple chemicals is predicted against multiple water quality indicators in the same way as is performed in a jar test. With the control function, the chemical dosing optimization is controlled by realizing both a target following capability and decrease of chemical expenses.
This system helps reduce chemical expenses by optimizing the chemical dosing rate and reducing the life cycle cost.
