Get Price- What are water treatment chemicals?
- Water treatment chemicals or simply common constituents of drinking water such as trace metals that are not toxic to humans may adversely affect them. Treatment chemicals such as chlorine, chloramines, fluoride, and others can affect the response of the test organisms or kill them outright.
- How are chemical and physical methods used in water treatment?
- Chemical and physical methods have been used to back each other up for many years, and that trend will continue for the near future. Coagulation and disinfection are the two stages in the water treatment process that are based principally on the introduction of chemicals into the feed water.
- How are water treatment technologies changing the world?
- Indeed, water treatment technologies are now using novel physical treatment methods. Membranes largely replaced granular filtration, and UV is paving the way towards minimization or elimination of the use of classic disinfection chemicals, such as chlorine and its derivatives.
- What is water treatment?
- Water treatment has a pre-set combination of separation processes applicable to water of almost every possible origin. This combination is a sequence of several robust processes, selected from a rather limited list of about twenty processes in total. The processes are applied in sequence, each in a separate reactor.
