Diseño y construcción de una planta de tratamiento de agua potable, para la Granja Agropecuaria Villacrecer en el sector Chiquilin, Riobamba, año 2016.

Abstract

In the present investigation, a water treatment plant was designed and constructed for the agricultural farm Villacrecer located in the area of Chiquilin, at Maldonado village in Riobamba canton. The water quality was evaluated with a chemical, physical and microbiological characterization of the laboratory taking three simple samples of irrigation water in the farm storage farm. On the other hand, it comes from the Chambo-Guano irrigation system. The parameters outside the limits allowed, in comparison with the technical norm INEN 1108-2014 of water for human consumption are: feacal coliforms, turbidity and color. Based on the results of the analysis, a purification system was proposed, consisting of a tray aerator, two slow sand filters, a chlorination system and a storage tank. With this, it is sought to obtain water suitable for human consumption from the irrigation water sector. After the implementation of the purification system and the analysis of the treated water samples, the parameters were reduced from an average of 524 colony-forming units CFU / 100 ml of feacal coliforms until the absence of them, turbidity at an average of 43.6 to 1.9 Nephelometric Turbidity Units (NTU), color of an average of 184.3 up to 27 units of apparent color. It was concluded that when implementing the system of purification, it meets the expectations and it allows to consume the water with confidence. It is recommended to give adequate maintenance to the plant so that it remains with the same level of efficiency as newly constructed. It is also recommended to surround the plant to prevent the entry of farm animal is can cause cross contamination of the drinking water.
