Diseño de un tratamiento de potabilización para agua subterránea empleada como fuente de consumo humano en el recinto san josé cantón naranjito-provincia del Guayas.

Abstract

The purification treatment was designed for a family from the San José compound, Naranjito canton, who, like the community of the compound, pump groundwater and use it for human consumption without an analysis and quality guarantee. The flow measurement was carried out applying the volumetric method, with which a value of 0.111 L/s was obtained. The underground resource was physically, chemically, and biologically characterized, obtaining a non-standard parameter that corresponds to total coliforms, which gave an average of 195 CFU/100 mL when the INEN 1108: Drinking water - Requirements standards stipulate its absence as a condition for a resource is fit for human consumption. The treatment chosen to comply with the regulations was a filtration process. Three filters with different compositions in filter media were made: a slow sand filter, a slow zeolite filter and a mixed slow filter (sand and zeolite) to compare the removal effectiveness of both sand and zeolite. A 100% removal was achieved with the mixed filter, managing to obtain a resource suitable for human consumption by complying with the permissible limits stipulated in the norm INEN 1108, constituting a feasible procedure in terms of operation and construction since the manufacturing cost is affordable for the community of San José. Sand is the filter medium that provides better removal processes compared to zeolite.
