Due to hydrolysis, aqueous solutions of calcium hypochlorite are alkaline. Calcium Hypochlorite; Disadvantages Because the chemistry is so similar to chlorine gas and NaOCl (“liquid chlorine”), this method offers no disinfection efficiency advantages (i.e., Giardia and Cryptosporidium kill rates) nor disinfection by-product advantages. Calcium hypochlorite showed the highest negative environmental impact due to its production phase. It restricts the growth of bacteria and algae, oxidizes organic contaminators that perishes in and around summing pools. Calcium Hypochlorite is a granular (or powder) product typically used to chlorinate swimming pools. Our study suggests that ozone surface disinfection treatments are preferable as compared with hypochlorite treatments from corrosion, economic, and environmental perspectives. Both sodium/calcium hypochlorite and hydrogen peroxide are commonly used to disinfect inanimate surfaces (e.g. Aqueous solutions of calcium hypochlorite are used in PT2 for disinfection purposes. As described above, upon dissolution of calcium hypochlorite in water, active chlorine is released.
