Physicochemical characterization and chlorination of well water consumed in Brazzaville-Congo [Caractérisation physicochimique et chloration des eaux de puits consommées dans la ville de Brazzaville-Congo]

Chlorination is a disinfection method largely known in water treatment. this treatment aims to eliminate pathogenic micro-organisms,bacteria,viruses and parasites as well as the majority of pyogenic less resistant. this is the way to provide drinking water without bacterias. the aim of our work is to monitor the quality of well water consumed in brazzaville (congo),for the determination of thephysicochemical characteristics,in a first step,then the break point in a second step to determine the optimal dose of chlorine needed to disinfect the water.
