Análisis de la arena volcánica como filtro en el tratamiento de aguas residuales de la lavadora Ram Jeans del cantón Pelileo provincia de Tungurahua

Abstract

For the development of this work, a field and experimental investigation was carried out that allowed us to know the current state of the textile garment washer that has its matrix and operates in the Pelileo canton. The flow rate of the washing machine under study was determined and the volume of water it occupies in the process of dyeing and washing jeans. From the field study carried out in the washing machine, the volume that is used in the washing and dyeing process of the textile garments was obtained in order to calculate the total flow used with these data. The average output flow was 4.12 L / sec, the average volume of water used in the process of washing and dyeing jeans is 592900 L / week respectively. In the laboratory of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato, the physical - chemical parameters of the residual water coming from the jeans washing machine were analyzed, generating results that are within the maximum permisible limits of the TULSMA. The highest reduction percentages obtained are of 88.52 percent of COD and BOD5 and 86.67 percent for the removal of color. Previous studies give us a guideline to assume that certain organic media have the capacity to act as natural resins, capable of removing contaminants through adsorption / absorption mechanisms. After conducting tests we can express that biofiltration with volcanic sand is an effective emanes capable of promoting waste from the wastewater of textile industries.
