Precautions for use of PAC in swimming pools

At present, the flocculants commonly used in the treatment of swimming pool water are alum and polyaluminium chloride. Alum is used because it dissolves in water and generates aluminium hydroxide, which attracts negatively charged impurities and collects in the water to clarify the water quality. Polyaluminium chloride is used because there are many micro-substances and sweat, cosmetics and microorganisms secreted by human activities in the swimming pool. It is difficult to remove with quartz sand filter alone or simple filtration. Therefore, the coagulant - Polyaluminium chloride PAC needs to be added. After dissolution, the product combines with impurities and organic matter in water to form large particles, which are then filtered by quartz sand to achieve the purpose of purification.

Polyaluminium chloride is used to purify swimming pool water, but the selection of polyaluminium chloride is strictly required. Generally speaking, it is necessary to choose polyaluminium chloride for spraying potable water. It not only has good effect, but also guarantees the health of people in swimming pools.

Swimming pools are mostly used in the summer, many of them leaking into the sky. The acidity and alkalinity of swimming pool water will decrease to a certain extent due to the influence of human or weather and rainwater. With the influence of rainwater, some bacteria, dust and algae will be produced in the water, which will affect the purifying effect of PAC. Therefore, it is necessary to regulate the swimming pool water to a certain extent, and then add polyaluminium chloride to treat the incoming water. When polyaluminium chloride is used for treatment, the amount of polyaluminium chloride is directly related to the treatment of swimming pool water.

When the amount of PAC is small, the flocculation effect is poor and the water purification effect can not be achieved. However, when the amount of PAC is too large, a large amount of precipitation will occur, which makes it possible to imagine floating and sinking. Changes in water temperature also affect the use of PAC in summer. Therefore, in summer, the appropriate temperature is usually selected at the end of the pool night. Polyaluminium chloride is very suitable for water treatment in swimming pools. It is not only effective but also economical to use 5-10 kg polyaluminium chloride per 1000 cubic meters of water.
