[Transformation of surfactants in different ways of water disinfection].
Evaluation of the efficacy ofoxidants on the destruction of bisquartemary ammonium salts (BAS) in water demonstrated that the highest destruction effectiveness was achieved upon exposure to ozone (87%), potassium permanganate (68.2%), ultraviolet radiation (37.8%), by chlorination with gas chlorine (35.4%), lime chloride (24.1%), the least destruction was achieved by chlorination with sodium hypochlorite (21.9%). There was a more than 2-fold increase in the level of low-molecular impurities upon chlorine exposure of the water containing BAS as a result of transformation processes. In ozone treatment of BAS, unlike its chlorination, there was as high as 2-fold decrease in the concentration of C6-C9 alcohols present in their composition, giving rise to C6-C9 aldehydes (0.5%) and C6-C9 organic acids (as high as 3% of the mass content).
