Diseño de un sistema de tratamiento del agua residual de la Fábrica de Textiles Hilario en el cantón Guano.

Abstract

A wastewater treatment system was designed to manufacture HILARIO textiles belonging to the canton Guano of Chimborazo province, since the waste water generated at the production plant is discharged directly onto the surrounding land without any previous treatment. The flow measurement was performed using the volumetric method during the 8 hours of the workday, determining a total average flow of 2.77 L / s, and a volume of 14958 liters of wastewater per day. Of the 2 types of fabric that are processed: polyester and poly cotton, for the subsequent physical chemical characterization. From this, it was known that only the wastewater from the poly cotton processing has high values of Oxygen (BOD5), Chemical Oxygen Demand (COD), Surfactants and Heavy Metals. Based on these data, it was decided to perform treatment tests Physical characteristics such as: coagulation-flocculation, sedimentation, filtration and chlorination, resulting in the removal of 96.23% of SDT, 96.32% of Color, 96.94% of DBO5, 97.34% of COD and 96.17% of surfactants. Thus, the parameters are reduced, adding them to the values required by the standard cited in TULSMA, Table 3: Water Quality Criteria for Agricultural Use in Irrigation; Concluding in this way that the treatment system is the ideal to get the treated water to the surrounding areas without any problem. It is recommended that the textile factory HILARIO implement the treatment system to comply with environmental regulations and avoid penalties.
