A selection of various by-merchandise may be get more info produced within the reactions inside the disinfection process. By-goods developed through the reactions between inorganic compounds and chlorine are harmless and will be quickly faraway from the water by filtration. Other by-products, including chloramines, are useful on the disinfection process because they also have disinfecting Qualities. On the other hand, there are undesired compounds That could be produced from chlorine reacting with organic and natural subject.
