Diseño de un sistema de filtración para aguas residuales de lubricadoras y concesionarias de la ciudad de Santo Domingo de los Colorados

Abstract

Because in the city of Santo Domingo de los Colorados wastewater is discharged without prior treatment, thus harming the environment. We began with the design of a filtration system for wastewater from lubricators and concessionaires of which a prototype of the filtration system was made to scale to observe its operation and check its efficiency, then a count of vehicles was made to calculate the design flow taking as an example the washing and lubricating machine "AUTO - SPA" in the city of Santo Domingo, with this data we proceeded to make a prototype of the filtration system to scale, with which we conducted operational tests obtaining an efficiency of 100 percent. To test the efficiency of the prototype filtration system, two samples of wastewater were taken, the first prior to the final discharge treatment at the aforementioned site and the second was obtained from the prototype filtration system at the final discharge, which consists of 5 stages to better treat the wastewater. The parameters that were evaluated from the wastewater sample were Biochemical Oxygen Demand (5 days), Chemical Oxygen Demand, Oils and Fats, Surfactants, Total Suspended Solids, Total Petroleum Hydrocarbons and Total Solids. With the data obtained from the samples, an analysis and comparison of data with the discharge limits to the public sewage system according to TULSMA was performed.
