Análisis de grava como filtro en el tratamiento de aguas residuales provenietes de la lavadora y tinturadora de jeans Dayantex, ubicada en el cantón Pelileo, provincia Tungurahua

Abstract

The purpose of this experimental work is to evaluate the efficiency of the gravel as filtering material, for an effluent that comes from the "DAYANTEX" a washer and dyeing of jeans industry. This study was carried out during four weeks in which two samples were collected and analyzed each four days, one before the filtration and another after the same, the parameters studied were: Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5) and color, to know the efficiency of the gravel. For which a metal structure was used to support the effluent; a connection was made from the base of the storage to the drip flute, so that in this way the water is distributed over the entire area of the filtering material. Also the real volume occupied by the industry and the volume of water to be filtered were calculated, for the estimated time. With the database, I could perform the analysis and calculations of the removal efficiency of wastewater pollutants, getting like this that the maximum values of removal are the following: COD= 74.47%, BOD5= 74.43%, Color= 51.72% of efficiency, which allows to determine that the gravel helps to obtain a considerable reduction in the treated parameters. This study ensures that the gravel can decontaminate an effluent of washer and dyeing of jeans industry, keeping an optimum efficiency.
