Abstract: China is a country which is seriously lack of water and it means a lot to treat water. The purpose of online dosing water treatment control system is to monitor the quality of the water. Online dosing control system is the monitoring of the water quality. In water treatment, we need to use reverse osmosis membrane, equipment such as scale inhibitor to get the water quality standards which we want. Control of water treatment introduced in this paper, based on the Smith estimates of PID controller is designed, and used the Matlab to do the simulation.
