Optimización del proceso de potabilización de agua en la PTAP "Chinchinloma", parroquia de Cusubamba : Optimización del proceso de filtración y de desinfección.

Abstract

The Chinchinloma purification station is in Santa Rosa de Cusubamba parish of the Cayambe Canton, it currently processes a flow of 3 L/s that receives water from Monte Verde and the Cangahua storage tank. The plant faces problems in the disinfection process since the chemical agent used in purification is applied empirically without considering the concentration, wear time, and residual free chlorine in the distribution network. In this context, the proposal was made to evaluate the quality of the filtered water of both the influent and effluent and optimize the disinfection process with the respective characterization of the fluid at the inlet and outlet of the process. Through dosage trials, an alternative disinfectant was tested, the one currently used in the plant in both tablets and powder. From the tests, the optimal dose of reagent to be used was obtained according to the quality of the water entering the process, the efficiency of removing contaminants from the filtered water, and the cost-benefit analysis of the disinfection. It was concluded that the gravel filter used in the plant can remove 100% ammoniacal nitrogen, turbidity at 75.59%, nitrites at 50%, and conductivity at 46.81%. Concerning disinfection, considerable optimization of the process was achieved with trichloroisocyanuric acid tablets, ensuring that the water sold from the plant.
