Diseño de una Planta de Tratamiento para Aguas Residuales de la Ciudad de Guaranda.

Abstract

"A treatment plant of residual water was designed in Guaranda Canton, Bolivar Province, to mitigate the environmental impact produced by their discharge in the Guaranda river.

Residual water samples were taken along seven days for the analyses whose data of Total Coliforms, DBO, and DQO surpass the permitted limits by the TULAS “Texto Unificado de Legislación Ambiental Secundaria”

The plant design includes three different treatments: first of all there is a waterway to. conduce the water between the grilles to retain the bigger solids complement whit two. sedimentation units to remove arena, after that is the primary treatment which includes three sedimentation units to remove minor size solids that arena will precipitate and reduces DBO, and DQO; the secondary treatment includes three oxidation units to. reduce the organic pollution. After that the treated water is likely to discharge in the river.

The Guaranda Municipality is recommended to implement this plant to improve the water quality flowing into the Guaranda River."
