Disinfection By Products In Drinking Water. A low drinking water standard of 10 microg l-1 has been set for bromate. In recent decade water pollution has become a global concern as the demand of safe water has increased. Disinfectants and Disinfection By-Products Introduction Disinfection of drinking-water is essential if we are to protect the public from outbreaks of waterborne infectious and parasitic diseases. Occurrence toxicity and abatement 1.
Which are detrimental to the human beings in terms of cytotoxicity mutagenicity teratogenicity and carcinogenicity. 2 of the most common types of DBPs found in chlorinated drinking water are trihalomethanes THMs and. Unlike things like arsenic and lead most people are not familiar with disinfection byproducts. However when selecting the appropriate disinfectant for a specific system it is important to note that disinfectants react with organics and inorganics in source water to form disinfection byproducts or DBPs. Chlorine can react with naturally occurring organic compounds found in the water supply to produce compounds known as disinfection by-products DBPs. The most common DBPs are trihalomethanes THMs and haloacetic acids HAAs.
In certain cases when bromide concentrations.
Many water companies have begun to use chloramines for disinfection instead of chlorine to prevent the formation of trihalomethanes. Drinking water disinfection by-products DBPs are an unintended consequence of using chemical disinfectants to kill harmful pathogens in water. Numerous organic and inorganic ozonation disinfectionoxidation by-products have been identified. In water THMs and HAAs were observed in the range from 0138 to 458 μgL and 016136 μgL. The chlorine reacts with decaying organic matter like leaves or vegetation from lakes and rivers to form DBPs. The goal of this article is to dive deep into the chemistry history and policy surrounding disinfection byproducts.
