Diseño de un sistema de tratamiento para las aguas residuales generadas por la Industria de Productos Lácteos “El Toril”, ubicado en el cantón Mocha-provincia de Tungurahua.

Abstract

A wastewater treatment system was designed for the “El Toril” Dairy Company, located in Mocha Canton, Tungurahua Province to due compliance with environmental regulations and achieve the objective of obtaining parameters within the discharge limits of the Official Registry of the Environmental Quality Regulations Water Resource of TULSMA, Book VI Annex 1, Table 9 “Limits of discharge to a body of freshwater”.The effluent is not constant, both inflow and composition, according to the product that the dairy company tends to elaborate. It has been carrying out the analyzes of physical-chemical characterization in samples composed per day formed by simple samples taken on Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday, allowed to distinguish the parameters outside the permissible limit according to the Environmental Quality Standard. According to the identified design flow and through a simulation at the laboratory level, the effluent purification equipment was sized, these being: Grid system, Oil and grease trap, Septic tank, Anaerobic upward-flow filter, and an era of dried. The design proposed was validated through the final characterization results of the residual water having average removal percentages of the analyzed parameters: Turbidity 95.20%, Oils and fats 91.24%, Suspended solids 59.66%, Total nitrogen 36.65%, Biochemical Oxygen Demand 61.40% and Chemical Oxygen Demand 69.29%. It is recommended to implement the wastewater treatment system proposed for the Company to avoid Environment contamination in the area of influence.
