Abstract

It was designed a System of Wastewater Treatment for San Luis de Pambil parish, Guaranda canton, province of Bolivar, in order to obtain treated water quality, reducing the concentrations of the parameters that are outside the permissible limit according to the Texto Unificado Legislación Secundaria Medio Ambiente to reduce the environmental impact on the ecosystem and water resources, to this end sampling and physical-chemical and microbiological characterization of wastewater from the parish San Luis de Pambil were carried out; five parameters outside the permissible limits were identified: total nitrogen, fluorides, biochemical oxygen demand, chemical oxygen demand and fecal coliforms. Jar testing and treatability testing laboratory for the respective design were made. Based on the results it was concluded that the system of waste water treatment consist of six elements: racks, sand trap, Parshall canal mixing tank, four upflow anaerobic filters and disinfection tank. The proposed design was validated by the results of treated water. 90.73% removal of total nitrogen, 87.10% of fluorides, 99.71% of biochemical oxygen demand, 99.85% of chemical oxygen demand and 100% fecal coliform were obtained. It recommends that the authorities in power system tend to the implementation of system of wastewater treatment for the recovery of water resources and improve the quality of life of the inhabitants of the sector.
