Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and ...
The dechlorinating bacteria use this H 2 as their electron donor, ultimately replacing chlorine atoms in the chloroethenes with hydrogen atoms via hydrogenolytic reductive dechlorination. This process can proceed in the soil provided the availability of organic electron donors and the appropriate strains of Dehalococcoides .
Chloramination is the treatment of drinking water with a chloramine disinfectant. [1] Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants.
Therefore, the concentration of free sulfur dioxide is greatly diminished by the time the beer or wine is consumed. When used to dechlorinate tap water, one tablet will effectively treat 20 US gallons (75 L) of water. [2] Campden tablets are also used as an anti-oxidizing agent when transferring wine between containers.
Also, graphene oxide coated nanofilter membranes helps in dechlorination of water. In addition to this, ultrathin nanofilter coated with graphene is the most potent filter that could be commercialized for water purification.
Iron minerals can active for dechlorination. These minerals use Fe 2+. Particular minerals that can be used include green rust, magnetite, pyrite, and glauconite. [6] The most reactive of the iron minerals are the iron sulfides and oxides. Pyrite, an iron sulfide, is able to dechlorinate carbon tetrachloride in suspension. [2]
