Indicators of organic matter in pure water

This equipment is manufactured by Wenzhou Haidoneng Environmental Protection Equipment Technology Co., Ltd. It is a 6 ton automatic reverse osmosis deionized water equipment with softening belt.

1. Organic indicators in pure water:

Organic indicators in the national standard is mainly reflected in chloroform (CHCl3) and the content of carbon tetrachloride.Because of bottled purified water quality problem focuses on microbial detection to exceed bid, in order to solve this problem, many manufacturers are not from the production process, quality management, but only by increasing the amount of disinfectant to try to solve the problem of pure water of microbial contamination, commonly used disinfectants for more chlorine disinfectants such as chlorine dioxide (ClO2), etc.Barreled pure water can produce some new organic halides due to chlorine disinfection, the main components are trichloromethane (chloroform) and carbon tetrachloride (CCl4) and a small amount of chloroform (CH3Cl), a bromodichloromethane (CHBrCl2), two bromochloromethane (CHBr2Cl) and bromoform (CHBr3), collectively known as haloalkanes.The content of halogenated alkanes in drinking water and tap water after chlorination is generally higher than that in source water.Among them, the content of chloroform and carbon tetrachloride is high, which is harmful to human body. If the pure water with excessive chloroform and carbon tetrachloride is drunk for a long time, it will lead to liver poisoning and even cancer in serious cases.In order to protect the health of consumers, in the national standard GB17324-1998 clearly stipulate: the content of chloroform and carbon tetrachloride in drinking pure water shall not exceed 0.02mg/L, 0.001mg/L respectively.
