Diseño de planta piloto de depuración de agua residual utilizando tecnología convencional y tecnología de membrana

Abstract

The design of the pilot plant for wastewater treatment using conventional technology and membrane technology was carried out considering the flow rate of 40 m³/d. It started with the sampling of industrial wastewater from “LEON´s” beneficiation plant in Portovelo´s canton of El Oro province, which had high contents of Aluminum 38,71 mg/L, Calcium 253,93 mg/L, Cadmium 0,38 mg/L, Manganese 15,51 mg/L, Mercury 4,35 mg/L and Plumb 4,22 mg/L. The heavy metals found in the wastewater will be removed using conventional technology and filtration technology through membranes that have theoretical removal values of 22 and 91%. The development of the research consisted in the design of the pilot plant for treatment by secondary treatment unit (sedimentation) and tertiary (microfiltration, ultrafiltration) to consider 2 alternatives of implantation relating cost and benefit. With the theoretical removal values obtained, it was determined that the membrane technology is simple, saves space and produces good quality water to be poured into a receiving body or be reused
