- Abstract:
- In building secondary pressurized water supply systems, water quality safety problems such as residual chlorine lower than the standard value at the end of pipe network or microbial breeding take place easily due to the long retention time of water in pipes or pools (tanks). Based on this, an intelligent sodium hypochlorite generator was applied to supplement chlorine to the secondary water supply drinking water, and the operational control mode, performance and operational cost of chlorination were analyzed. In this system, chlorine was supplied at the inlets of upper and lower cisterns together. When the residual chlorine at the outlet of the cistern was lower than 0.2 mg/L, the intelligent sodium hypochlorite generator would produce sodium hypochlorite according to the volume of the cistern, and dilute and supplement sodium hypochlorite automatically. The equipment had the advantages of simple control and stable residual chlorine at the end of the pipe network and improves the safety of the water supply when it is applied in chlorination of the secondary water supply system.
