The purity of the DI water may be to low for the intended use. For example, the free chlorine in the DI water can potentially cause corrosion or dendritic growth if the DI water is used on circuit board assemblies. It would be best to use the pool chlorinator only as long as ...
Chlorine-free aq. chlorine di:oxide soln. prepn. - by adding chlorite to water, acidifying, adding metal hydroxide and then carbonateIn Parent Patent, aq. ClO2 solns. are prepd. by dissolving 7-21 pts. wt. chlorite, 7.5-25-5 pts. wt. hypochlorite and 0.5-1.5 pts. wt. carbonate in ...
THMs are formed during the disinfection of water with free chlorine. Because of their carcinogenic potential and other negative health effects, THMs are regulated by the Environmental Protection Agency (EPA). TOC—Total organic carbon which is a measurement of the concentration of organic carbon in...
present invention is easy to implement short-term transfer of free chlorine to chloramines, clear pool structure, plus ammonia point and mixing device designed to ensure complete chlorine or ammonia, quickly and uniformly dissolved in the water, no chlorine or ammonia to escape, short flow ...
recovery from soln. in the electrolyte leaving membrane cells in the electrolysis of aq. alkali chloride solns. involves treatment with alkali hydroxide to form alkali chlorate, liberation of C12 from the resultant chlorate and the chlorate formed in the membrane cell in the anolyte and return of...
