Diseño de la planta de tratamiento de las aguas residuales generadas en la Comunidad Unión Chimborazo de la Parroquia Nuevo Paraíso del Cantón Francisco de Orellana – Provincia de Orellana

Abstract

The sewage treatment system designed for Union Chimborazo Community, Francisco of Orellana Canton, Orellana Province aims to recover the sewage through primary and secondary treatment taking care of the environment and avoiding pollution of effluents which are close to the discharge. The characterization of sewage was carried out through a physical-chemical and microbiological analysis which defined the method to be used for designing and efficient system for the point source pollution. According to the results verified by different certified laboratories, Fecal and Total Coliforms resulted in 160000 and 180000 UFC/100mL respectively, oils and fat in 2,5 mg/L, according to TULSMA (Unified Text of Secondary Legislation of the Ministry of Environment) these parameters fail to fulfill the permissible discharge limits in nearby effluents. In addition the quantification of the daily flow was carried out without significant variations. As a result, a sustainable and efficient design to diminish the level of contamination of the sewage discharge was obtained; this fulfills the maximum permissible limits established by the Ecuadorian regulations, improves the inhabitant`s quality of life and diminishes the environment impact. Since there are several small communities in Francisco of Orellana Canton like Union Chimborazo Community, it is recommended to the Municipality of Francisco of Orellana to implement the sewage treatment system due to its efficient and low implementation cost.
