摘要: Abstract In the search for new disinfection technologies reused water, in this work effect of current density on capability, during electrolyses with conductive diamond anodes effluent a municipal wastewater treatment plant was evaluated. It found that electrolytic technology can disinfect completely densities ranging from 1.3 to 130 A m − 2 , but rate and chlorine speciation are significantly affected by particular applied. order avoid occurrence non desired species, lower value range is proposed. those conditions, complete be obtained hypochlorite chloramines main not being produced chlorate, perchlorate or organo-chlorinates species.
