Optimización del proceso de coagulación en el tratamiento de agua a partir de la adición de basificantes en la planta de tratamiento de agua potable Casigana de la EP-EMAPA-A

Abstract

Adding basifying used in drinking water allows conditioning it for optimal treatment, mainly influencing physicochemical parameters such as turbidity, pH, total dissolved solids and alkalinity in the coagulation process. Therefore, different basifying agents such as sodium hydroxide, calcium hydroxide, sodium carbonate and calcium carbonate 5percent, taking as factors study the concentration of coagulant, as well as the added volume of base for an optimal removal of the turbidity. For which three water samples used with high turbidity from the Huachi-Pelileo channel captured in the Casigana drinking water treatment plant of EP-EMAPA-A in the wet season. Jar test was used for the different treatments, the best basifying being calcium hydroxide (a1b2c1) with a removal of 99.4 percent of turbidity, allowing the reduction of at least 20 mg por every L of coagulant and according to the norm INEN NTE 1108: 2014 the parameters evaluated are within compliance with the permissible limits used for drinking water.
