Análisis del aserrín como filtro en el tratamiento de aguas residuales provenientes de la lavadora de autos Monster Wash ubicada en el cantón Ambato

Abstract

To evaluate the effectiveness of the filtering material in the experimental project, different types of physical-chemical analysis were considered in three parameters: Oxygen Biochemical Demand (BOD5), Chemical Oxygen Demand (COD) and Oils & Greases (A & G). The efficiency of the filter is verified during a period of 90 days of operation, within this period samples of raw water and filtered water were taken every 10 days, to be later analyzed in a specialized laboratory (accredited), which guarantees good results. The structure that makes up the filter is made of metal, with a height of 1.60 m, on which the 55-gallon tank rests, which will contain the residual water from the car washer. The tank must be filled daily during its period of operation. The filtering material formed of sawdust will be inside a plastic container which will receive the residual water from the tank through a pipe, and thus be able to obtain the treated liquid. The values obtained indicate that the filtering material decreases the contamination of the parameters analyzed, and in turn verify that the filtering material used in the filtration process shows a high level of effectiveness in the filter.
