Rediseño de la planta de tratamiento de agua potable de la Empresa Municipal de Faenamiento de Ganado de Orellana

Abstract

In the present investigation, the Redesign of the Drinking Water Treatment Plant of the Empresa Municipal de Faenamiento de Ganado de Orellana, Cantón Francisco de Orellana, Province of Orellana was carried out. The research process was based on the Inductive and Deductive Method, which allowed the physical, chemical and microbiological characterization of the water was carried out by simple sampling, using amber glass containers and sterile flasks, the analytical calculations were performed by the Laboratory of Soil Water and Plants (LABSU) basing the analysis procedure on the APHA-AWWA-WPCF Standard. Water characterization: Coliforms (CF=13.33 Col/100mL and CT=90 Col/100mL), Mesophilic Aerobes (2566.7 Col/100mL) and real color (19.33 Pt-Co) were found in the distribution network due to contamination in the cistern tank by external factors, this assertion is made based on the absence of Coliforms in the water collected; In the case of the water analyzed from the reserve tank, the presence of manganese (0.43 mg/l), total iron (0.47 mg/l) and dissolved oxygen (5.90 mg/l) is evident. The tests carried out in the jar test equipment resulted in the removal of manganese, iron and color in 89.54%, applying 6.48x10-3%(v/v) of chlorine, 0.02% (w/v) of PAC and 0.019% (w/v) of lime and finally filtered in a dual medium of sand and gravel (pilot filter). To improve the quality of the treated water, it is necessary to implement a desander, a new coagulation and flocculation dosing system, and change the filter bed, based on the studies conducted, to comply with the provisions of the Technical Standard for Drinking Water NTE INEN 1108:2011. It is recommended that Empresa Municipal de Faenamiento de Ganado de Orellana implement the processes described above and adequately control and maintain the plant to ensure the quality of the treated water.
