Optimización de la planta de tratamiento de agua potable de ciudad de Chambo

Abstract

Optimization of the drinking water treatment plant of the city of Chambo, located in the El Mirador sector. The experimental method and analysis technique were used in this research work, for which physical, chemical and microbiological characterizations were made, both at the entrance and exit of each stage of the treatment process, and tests of Aluminum Polychloride dosage; the tests were carried out in the Quality Control Laboratory of the National University of Chimborazo. To dose the Aluminum Polychloride, a hydraulic mixer was designed in Rectangular Spillway, which has a width of 0.40 m, a height of 1 m, a length of 2.06 m, the water with the chemical will leave the mixer, it will pass immediately to the horizontal flow hydraulic flocculators, which will be 11.85 m long inside, each flocculator will be 3 m wide, 36 cement baffles of 3 cm thick, each baffle will be 2.50 m wide. Designing the mixer in a rectangular weir, horizontal flow hydraulic flocculators and correctly dosing the Aluminum Polychloride will increase the efficiency by 70% sedimentation. A redistribution of gravel in the pre-filters and corrective maintenance of each stage of the treatment process were carried out. It was concluded that the improvement alternatives for the operation of the drinking water treatment plant will increase the sedimentation efficiency by 70%, the redistribution of gravel will increase the pre-filtration efficiency by 80%, and the execution of the maintenance plan for each of the stages will reduce the phosphates that exceed the standard. It is recommended that the study be implemented to improve the efficiency of the drinking water treatment plant, providing quality service to the citizens of Chambeña.
