How to do well in swimming pool water treatment?
A Water quality treatment:
1. Precipitation: coagulating agent to coagulate and precipitate water. Polyaluminium chloride is released according to the instruction manual. When the drug is put into operation, the drug should be fully diluted and evenly distributed into the pool surface.
2. absorb dirt: after putting coagulant, it is best to circulate the system for half an hour. When floc is present in the water, it will remain stationary for 6~8 hours, and then the sediment will be discharged by the suction equipment. Be patient and careful when taking dirt. Do not take too long (within 2 hours).
3. Disinfection: Chlorine-containing disinfectants (chlorine dioxide, trichloroisocyanuric acid, dichloroisocyanuric acid, sodium hypochlorite, etc.) were used to disinfect the pool water, so that the residual chlorine content in the pool water was kept at 0.3-0.5mg/L, and the residual chlorine in the pool water was determined regularly. The dosage of drugs is strictly implemented according to the instruction manual.
4. matters needing attention in drug use:
a. Adjust pH value: PH regulator generally makes sodium hydroxide (alkali tablets) and hydrochloric acid. When swimming pool water is running water, the pH value of the pool is generally 6.5 to 8.5, and no pH value is required. When pH is low, sodium carbonate or sodium hydroxide can be used to raise the alkalinity of the pond water. When the pH value of water is higher than 8.2, it can be appropriately injected into hydrochloric acid.
b. Chlorine containing disinfectants
When the water temperature is above 30 C or the color of water turns green, the dosage should be increased appropriately.
c. Use of alga drugs:
The use of algae removers is generally not advocated, and algae can be removed by periodically increasing the concentration of chlorine-containing disinfectants. If a bug or moss is found, the algae remover copper sulfate can be thrown into the water that is fed into the swimming pool, and other steps of water treatment can be carried out after two hours. The dosage of copper sulphate is 2 to 3g/M3 water.
B. Matters needing attention in circulating filtration water treatment:
1. When the circulating filtration system is started for water treatment, there will be at least 2 cycle cycles per day.
2. regularly carry out the backwash of filter tank.
3. Wash hair filters frequently.
4. Put precipitating agent in front of the tank, add a small amount of polyaluminium chloride every day, according to the dosage of 0.1g/M3 water. This will reduce the frequency of dirt absorption, but enhance backwash.
