Ácido peracético como alternativa de desinfección en el proceso de potabilización de agua para consumo humano
Abstract
The purpose of the present work was to evaluate the quality of Peracetic acid (APA) as a disinfectant agent in the process of purification of water for human consumption. For this, 4 water samples, taken from the same point in the Magdalena river, were analyzed during different days. Each sample was submitted to the process used to purify water, characterize raw water, rapid mixing (coagulation), slow mixing (flocculation), sedimentation, disinfection and physicochemical and microbiological characterization. Each water sample was subjected to two tests with 12 jars each, a sample with sodium hypochlorite and another with APA as a disinfectant, to compare the characteristics obtained in the purification process. The results obtained show that when using APA as a disinfecting agent in the purification process, the physical chemical parameters obtained in comparison with those of sodium hypochlorite are maintained in similar ranges, there is no significant variation in terms of pH, color, turbidity. Temperature, hardness and alkalinity. Regarding the microbiological results, no pathogenic presence was found in the samples analyzed. Being able to conclude that the APA is a good alternative as a disinfectant agent in water purification. Finally, each of the parameters analyzed was compared with the Colombian legislation for drinking water, and the APA met the standards established in each of the corresponding articles
