Swimming pool water treatment specific steps
1.Test water quality. We generally use residual chlorine test box or six in one test box to understand the chlorine content, alkalinity, hardness, PH value, combined chlorine and other values in the swimming pool water.
2. adjust PH value, PH value in 7.2~7.8 is the best efficacy. When disinfection powder or tablet is added to the swimming pool for disinfection, we know that the disinfectant will hydrolyze into HOCL hypochlorite (commonly known as residual chlorine) and OCL hypochlorite - in the water, and the main oxidation, disinfection and algae killing effect is HOCL hypochlorite. When the same amount of drug is used, HOCL hypochlorite and OCL hypochlorite - will have different ratios under different pH values, that is to say, free effective chlorine will have different activity percentages under different pH values
3. Kill algae with algicide first, then disinfect.
4. In the use of precipitant to do precipitation, flocculation.
5. pollution. In the process of suction, we should pay attention to, not to save time, so that the suction machine in the swimming pool quickly crawling suction, which will make the pool of dirt is difficult to completely remove, because the suction machine fast crawling makes the pool water up and down, sediment can not precipitate.
