Swimming pool water treatment swimming pool water purification steps
Generally, the following steps are adopted to purify the water quality of swimming pools: coagulation? Clarify? Suction tank? Disinfect? Circulating filtration
Coagulation: impurities in water are flocculated and bridged by coagulants such as aluminum salt, iron salt and polymer to generate large-particle sediment, which is then removed by suction filtration.
Clarification: the coagulant forms large particles, the swimming pool is statically separated, the sediment sinks to the bottom of the pool, and the upper layer gets clarified water.
Suction pool: the sediment settled at the bottom of the swimming pool is removed by a special swimming pool suction machine.
Disinfection: add disinfectant to kill bacteria, viruses and algae in water.
Circulating filtration: The treated water will flow through a device filled with special filtering materials such as quartz sand and activated carbon through a pump to intercept the residual impurities in the water and further purify the water.
General swimming pool water treatment, the application method is:
1) Stop and prevent the growth of moss.
Put copper sulfate, the dosage is two to three kilograms per 1000 cubic meter of water, once or twice a month (for insects and mosses).
Copper sulfate, called alum, is an algaecide. It crystallizes in the blue asymmetric triclinic system and is powdery. When it melts in water, it kills and resists the growth of microorganisms, so that the pool water can adjust the blue of seawater.
After placing copper sulfate for two hours, do the following:
2) adjust the PH value (PH value). There are two kinds of drugs to adjust pH value:
Sodium carbonate (soda), white powder, fine particles, soluble in water, alkaline, low PH value. When using this medicine, the PH value will increase by about one degree, and one cubic meter of water is15g.
Hydrochloric acid, strongly acidic, with PH above 8.2, can put 5- 10 kg per 1000 m3.
The PH value of pool water is 7.5. ~8.0.
3) sterilization and disinfection
4) precipitation
Polyaluminum chloride (PAC) is pressed for one kilometer. Thirty-five to ten kilograms.
After being put into the open circulation system for half an hour, the water is snowflake-like, and it is allowed to stand for six to eight hours until it is vacuum.
5) Suspended matters in dust collection are the main sources of turbidity, chromaticity and odor of water quality.
The content of water is unstable and varies with seasons and regions.
