What Are Trihalomethanes?

Trihalomethane

Trihalomethane

The health effects of trihalomethanes are mainly for chloroform, as it is the most frequent and most influential in drinking water.

Chloroform can degenerate the central nervous system and also affect liver and kidney functions. The immediate toxicity of chloroform is often unconsciousness, which can then lead to death with coma. After 24 to 48 hours of exposure to chloroform, the kidneys are injured, and liver damage can be found after 2 to 5 days. The coma caused by chloroform will take several days to recover.

Against

Techniques considered in the literature for removing trihalomethanes and trihalomethane precursors include: oxidation, aeration, adsorption, resin, clarification (such as

There are many researches on the formation and control technology of THMs at home and abroad, but the formation mechanism of THMs and the types of precursor organic substances in natural water are not very clear. In addition, although there are many studies on THMs control technology, the real price is low and the effect is good. There are few technologies that can be widely promoted. So far, chlorine disinfection has the advantages of fast sterilization effect, convenient use, low processing cost, and convenient operation and management, etc. It is still the main disinfection method.
