Rediseño del sistema de tratamiento del agua residual para la Extractora de Palma Aceitera La Sexta.

Abstract

“It was held the redesign of system on treatment of residual water from the oil Palm Extractor “LA SEXTA” in Canton Quinindé, Esmeraldas Province, in order to avoid the pollution generated by the extraction process of oil palm. For this purpose, it starts with the diagnosis of the current state of plant. Then, flows are determined and the characterization is performed following parameters outside the norm: Biological Oxygen Demand (DBO) = 4000 mg/l, Chemical oxygen demand (DQO) = 20800 mg/l, Total Solids (ST) = 6920 mg/l, Suspension Solids (SS) = 1900 mg/l, Total Coliforms = 286 x 10 7 UFC/100 ml, and Fecal Coliforms = 126 x10 7 UFC/100 ml. With the data obtained, treatability tests were performed to obtain the optimal dose of ferric chloride to 2.5%, and Anionic coagulant 0.25%. The proposal of redesign will consist with sedimentation processes, diffusion aeration, coagulation – flocculation and filtration to treat a flow of 302.4 m 3 /day, and wherein the reduction parameters the following values are obtained; Biological Oxygen Demand (DBO) = 520 mg/l, Chemical oxygen demand (DQO) = 780 mg/l, Total Solids (ST) = 720 mg/l, Suspension Solids (SS) = 120 mg/l, Total Coliforms = 161200 UFC/100 ml, and Fecal Coliforms = 7500 UFC/100 ml. In conclusion. It is advised to constantly monitor the processes established”.
