Copper sulphate is the cheapest algicide (copper sulphate is indeed an algicide even used in industrial water treatment, but now with the rise in international copper prices, the price of copper sulphate is much higher than the price of chlorine preparation) Many people think that the use of blue copper sulphate will make the pool water blue. In fact, copper sulphate relies on copper ions, but copper ions in water will be easy to use with hydroxide, carbonate and oxidant in water. When combined, it forms a pale blue copper hydroxide, a peacock green copper carbonate or a black copper oxide which is insoluble or has low solubility, thereby causing coloration of the cell body, affecting the appearance and losing the algae-killing function, especially in The swimming pool water is used in the presence of chlorine. At this time, the oxidizing power of chlorine is sufficient to oxidize the copper ions into black copper oxide precipitates, and the administrator thinks that the swimming pool has long spirulina and then uses copper sulphate to form a vicious circle.
Copper ions in copper sulphate are heavy metals, which are toxic substances to the human body. When copper sulphate is used too much, it will make the pool water have a sweet taste. After the swimmer’s hair is sun-dried, it can be found in the hair. Crystallized like quartz sand.
It is generally not recommended to use copper sulphate as an algicide in the water quality management of swimming pool equipment pools. The chlorine preparation used for disinfection of swimming pool water itself has a strong algicidal effect. When the free chlorine content of the swimming pool water is maintained at 0.5~1.0ppm, it is enough to inhibit the growth of bacteria and algae, such as changes in external environmental conditions. In the case of long algae, it is already sufficient to use a chlorine preparation for SHOCK (impact treatment).
