Optimización del sistema de tratamiento de aguas residuales de la planta piloto de la lavadora de vehículos Octupus del cantón Ambato

Abstract

In the present experimental work, the optimization of the wastewater treatment plant, built in the “Octopus” vehicle washer, was carried out. In the first instance, possible optimization methods for the wastewater treatment plant were analyzed for each stage of its process. Based on the information obtained, the method consisting of a galvanized steel structure with polycarbonate sheets was selected, which was placed in the settler, which aims to increase the hydraulic retention time. Natural coagulant (Moringa Oleifera) was also used in the settler and grease trap. Maintenance of the wastewater treatment plant was carried out, cleaning it and changing the filters (Peat Bed, Volcanic Pyroclastic and Activated Carbon). Once the cleaning and optimization had been carried out, the samples were taken, which consisted of a sample of two liters of water during a period of eight weeks, in which the: BOD that is consumed during 5 weeks was determined by physicalchemical analysis. days, COD, Total Suspended Solids, Settling Solids, Oils and Fats, Temperature, pH and Surfactants as well as Color, Conductivity and Turbidity analysis. The results obtained in the laboratory were compared with the limits established by TULSMA for effluents that can be discharged to the public sewer network in which all the determinations complied with the regulations, giving a decontamination effectiveness of 93 percent.
