Can hydrogen peroxide be used for cooling tower water disinfection?
Hydrogen peroxide can be used for cooling tower water disinfection, when it is combined with other disinfectants. Peracetic acid (CH3COOH, PAA) can also be used for cooling tower water disinfection. Does hydrogen peroxide remove chlorine? Hydrogen peroxide can be used for dechlorination, in other words to remove residual chlorine. Residual chlorine forms corrosive acids when it is oxidised by air or condensates on process systems. When chlorine reacts with hydrogen peroxide, hydrogen peroxide falls apart into water and oxygen. Chlorine gas hydrolyses into hypochlorous acid (HOCl), which subsequently ionises into hypochlorite ions (OCl). Cl2 + HOCl + H+ + Cl HOCl + H+ + Cl After tha, hydrogen peroxide reacts with hypochlorite: OCl- + H2O2 (g) -> Cl- + H2O + O2 The reaction between hydrogen peroxide and hypochlorite takes place very quickly. Other organic and inorganic substances cannot react with hypochlorite. What are the advantages and disadvantages of hydrogen peroxide use? Advantage
