Efectos de la descarga de dos Plantas de Tratamiento de Aguas Residuales domésticas sobre la calidad del río Daule.

Abstract

The research analyzes the environmental impact of treated water discharges from two treatment plants in the Daule River. The study aims to evaluate the quality of water at points close to the discharges, using physical and chemical parameters such as pH, total solids, suspended solids, biochemical oxygen demand (BOD), and fecal coliforms. Through sampling in the Daule and Palestine cantons, water samples were taken near the discharges and at different points of the river. Subsequently, these samples were analyzed in the laboratory to compare the results with the limits established in Ecuadorian environmental regulations and with previous studies. The results showed that the fecal coliform parameter was the only one that did not meet the standards of the environmental standard in both cantons according to the samples taken on site. The study concludes with the proposal of an improvement plan for the treatment plants and recommendations to ensure compliance with regulations and reduce the impact on the Daule River.
