Trichloroisocyanuric acid, abbreviated as TCCA, is a chlorinated derivative of isocyanuric acid with an effective chlorine content of up to 90%. Trichloroisocyanuric acid is a highly effective, low toxicity, stable, broad-spectrum and fast disinfectant that can quickly and effectively kill various bacteria, spores, fungi, molds and cholera. Therefore, TCCA is also the most widely used and widely used swimming pool disinfectant in China.
The main component of the bleaching powder is calcium hypochlorite, which is a disinfectant with a relatively common use and good bactericidal effect. In an acidic environment, it has strong bactericidal power and rapid response. However, the bleaching powder is used excessively, the aqueous solution is alkaline and has sediment, and there is a layer of white floating matter on the surface of the water, which has a stimulating effect on the gastrointestinal mucosa, respiratory tract and skin of the human body.
Bromochlorohydantoin is commonly known as bromine tablets, which are more stable than chlorine preparations, have a milder odor, and are less sensitive to changes in pH than chlorine. However, bromine preparations are corrosive at high doses, which are strongly irritating to human skin, eyes and cells, and at the same time produce a carcinogen, bromate, under pool conditions.
These disinfectants must reach a certain dose to produce a hazard. The amount of residual chlorine is an important indicator to determine whether the swimming pool water is up to standard. It means that the amount of application is enough to kill bacteria and viruses and there is still remaining, which can ensure the disinfection effect of the water body.
