In this work alternative methods for drinking water disinfection are studied: UV-C germicide radiation and Peracetic Acid. These could be a replacement for chlorination which generates, under certain conditions, halogenated substances that are mutagenic. Experimental runs were carried out in a batch reactor, in order to evaluate the effectiveness of the selected agents and the damage to bacteria during disinfection. A high efficiency was demonstrated for the studied processes. It was proved that damage from different agents to DNA can be analyzed through ERIC-PCR. Quantitative and qualitative results were obtained in terms of the damage caused to DNA from these processes. The results obtainedwould allow the development of a disinfection kinetics study based on damage quantification.
