An apparatus for controlling the quality of water in real-time is provided to maintain the stable quality of water and satisfy a desired CCPP(Calcium Carbonate Precipitation Potential) condition of tap water, by monitoring the change of water quality in real-time and automatically putting corresponding chemicals according to the monitoring result. Raw water is treated via a pre-chlorine bath(10), a pre-ozone bath(20), a condensing bath(30), a filter bath(40), a post-ozone bath(50), an activated carbon bath(60), and a post-chlorine bath(70). A first chemical bath(100) is installed between the pre-ozone bath and the condensing bath. A second chemical bath(200) is installed after the activated carbon bath. Calcium hardness and pH of the treated water are firstly controlled by putting Ca(OH)2 and CO2 into the first chemical bath. Alkalinity and pH of the treated water are secondarily controlled by putting Na2CO3 and CO2 into the second chemical bath. The Calcium hardness and pH are feedback-controlled by additively putting Ca(OH)2 and CO2 into the first chemical bath when the calcium hardness and pH are below the standard values, through a monitoring controller(PLC) and a monitoring control server(PC). The alkalinity and pH are feedback-controlled by additively putting Ca(OH)2 and CO2 into the second chemical bath when the alkalinity and pH are below the standard values, through the monitoring controller and the monitoring control server. |
