Evaluación y diseño de un sistema de tratamiento de agua residual para la Fábrica Textil Hilario.

Abstract

In Ecuador, the Ministry of the Environment is in charge of regulating the discharges of residual liquid effluents produced by human or industrial activities, in the case of textile industries they have a high environmental impact, due to the high water consumption and nature of the different pollutants, emphasizing dyes. The textile factory Hilario located in the Guano canton, reflects this problem, which is why it is essential to install a wastewater treatment system to avoid soil contamination and the consequent decrease of its fertility in the area where the effluent is discharged. Which is mistakenly used as water to irrigate the vegetation surrounding the production plant. A PTAR design is proposed, which start swith the flow easurement and a composite sample of the wastewater coming from the two types of fabric that are processed: polyester and poly cotton, the water quality is known by a physical chemical characterization and From these results it is determined that only the water of the poly cotton process, presents high values in parameters such as: Total Dissolved Solids (TDS), Color, BOD, COD, Surfactants and Heavy Metals. The treatability tests guide us to the selection of the most appropriate treatment system, which will consist of physical-chemical treatments such as: coagulation- locculation, sedimentation, filtration and chlorination.
