Diseño de una Planta para la Producción de Agua Apta para el Consumo Humano en la Planta de Producción de la Familia Sancela S.A.

Abstract

The objective is to supply vital liquid to the personnel of the production plant of Familia Sancela S.A. located in Lasso, Cotopaxi Province, which is currently supplied by private companies, assuming costs for its consumption. The company has access to the Cutuchi River basin, which carries a variety of components, making it necessary to characterize and purify the river water by taking scheduled samples. The physical and chemical analyses were carried out in the plant's laboratory, using burettes, pipettes, beakers, flasks, equipment, etc. Scientific-analytical methods and volumetric, calorimetric and spectrophotometric techniques were applied. The values to be followed are from the INEN 1108 Standard for Drinking Water, obtaining parameters within the standard with a very slight variability, except for turbidity, color and bacterial contamination. With these data, the design of the coagulation and filtration plant for the removal of turbidity, color and microorganisms is justified. The treatability data show that the characterization values are reduced in: Total Coli by 98.96% and Fecal Coli by 98.99%. The turbidity of the water is reduced by 98.47% after treatment with a dosage of 30 ppm, and the color is reduced considerably by 85.71%. The design is based on the needs of the plant, the possibility of applying the water in the production process and an increase in the plant's productivity. The design consists of a catchment tank of 1320 m3 of capacity, which the Production Plant has, passing through a Parshall rapid mixing channel, to be directed to a vertical flocculator with a detention time of 25 min. Then it is directed to a high rate settler with a volume of 36 cubic meters and a surface load of 175 m/m/day, finally a system of 4 filters, with a filtration rate of 240 cubic meters...
