Resumen
El Denim es un material reconocido por su diversidad de estilos, comodidad y versatilidad. Una limpieza adecuada de las confecciones de mezclilla conserva su atractivo estético y permite que dure por muchos años, esta es una de las actividades que se realiza en la UEB 102 Juan Pedro Carbó Serviá de la empresa de Confecciones Fénix, la cual genera un alto contenido de contaminantes para el medio ambiente al realizar el vertimientos de sus aguas fuera de los parámetros normados. En el presente trabajo se identificó el problema ambiental y se desarrolló una alternativa de tratamiento para los residuales líquidos combinando la biosorción con otros métodos para minimizar los daños que provocan esas descargas. En el trabajo se dimensionaron los equipos principales y auxiliares los cuales son una rejilla de acero galvanizado con diámetro de alambre de 1.5 milímetros, tanque de ingreso de aguas residuales, un sedimentador donde ocurre la coagulación-floculación y una etapa de adsorción compuesta por batería de cestos cargados con bagazo los cuales en su conjunto permiten tratar el agua residual, seleccionando también los instrumentos automáticos apropiados para mantener el control en el proceso estos son medidores de caudal, nivel y peso respectivamente. Se realizó un análisis económico minucioso de la planta a instalar dando como resultado 1 790 401,94 pesos el costo total de inversión y 656 296,65 pesos al año el costo de operación.
Denim is a material recognized for its diversity of styles, comfort and versatility. Proper cleaning of denim garments preserves its aesthetic appeal and allows it to last for many years, this is one of the activities carried out in UEB 102 Juan Pedro Carbó Serviá of the Confecciones Fénix company, which generates a high content of pollutants for the environment when discharging its waters outside the regulated parameters. In the present work, the environmental problem was identified and an alternative treatment for liquid waste was developed, combining biosorption with other methods to minimize the damage caused by these discharges. In the work, the main and auxiliary equipment were dimensioned, which are a galvanized steel grid with a wire diameter of 1.5 millimeters, a wastewater inlet tank, a settler where coagulation-flocculation occurs and an adsorption stage composed of a battery of baskets loaded with bagasse which together allow treating the residual water, also selecting the appropriate automatic instruments to maintain control in the process, these are flow, level and weight meters respectively. A detailed economic analysis of the plant to be installed was carried out, resulting in 1,790,401.94 pesos the total investment cost and 656,296.65 pesos per year in the operating cost.
