Chlorine dioxide is also superior to chlorine when operating above pH 7, [17]: 4–33 in the presence of ammonia and amines, [28] and for the control of biofilms in water distribution systems. [25] Chlorine dioxide is used in many industrial water treatment applications as a biocide, including cooling towers, process water, and food processing ...
In addition to being highly influenced by the types of organic and inorganic matter in the source water, the different species and concentrations of DBPs vary according to the type of disinfectant used, the dose of disinfectant, the concentration of natural organic matter and bromide/iodide, the time since dosing (i.e. water age), temperature ...
[citation needed] Silver ion/chlorine dioxide-based disinfecting agents will kill Cryptosporidium and Giardia, if utilized correctly. The primary disadvantage of silver ion/chlorine dioxide-based techniques is the long purification times (generally 30 minutes to 4 hours, depending on the formulation used).
Chlorine and oxygen can bond in a number of ways: chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII ...
The most common disinfection method involves some form of chlorine or its compounds such as chloramine or chlorine dioxide. Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use.
Commercial swimming pools also require chemical dosing in order to control pH balance, chlorine level, and other such water quality criteria. Modern swimming pool plant will have bulk storage of chemicals held in separate dosing tanks , and will have automated controls and dosing pumps to top up the various chemicals as required to control the ...
Chlorine dioxide has emerged as the preferred biocide against anthrax-contaminated sites, having been employed in the treatment of numerous government buildings over the past decade. [98] Its chief drawback is the need for in situ processes to have the reactant on demand.
The product of the process, sodium hypochlorite, provides 0.7% to 1% chlorine. Anything below the concentration of 1% chlorine is considered a non-hazardous chemical [according to whom?] although still a very effective disinfectant. The sodium hypochlorite produced is in the range of pH 6-7.5, relatively neutral in regards to acidity or baseness.
