Item Evaluación del efecto de la plata coloidal sobre la calidad química del agua filtrada de dos modelos de filtros caseros(Universidad Santiago de Cali, 2019) Avilés Torres, Bryan Camilo; Narváez Garavito, María Alejandra; Silva Leal, Jorge AntonioThe purification of water and sanitation is a public health problem, where the technological gap in water treatment systems between the urban and rural population is evident, therefore, to minimize this problem, various treatment systems are implemented to supply water. Drinking water of communities with socio-economic limitations among them are the systems of home purification as the filter system by filtering bed of ceramic vessel. In this study we evaluated a ceramic pot filtration system, called Ekofil and Ekofil plus, which consists of a clay pot impregnated with colloidal silver and the Ekofil plus that has an activated carbon cartridge reinforcement impregnated with colloidal silver. The concentration of silver on the filtered effluent was evaluated in two models of ceramic pot filters used in the treatment of water for human consumption, for which the measurement of two types of synthetic water was carried out under controlled laboratory conditions for 10 weeks. The results obtained in both filtration models showed that the silver leaching was below the limit of 0.1 mg / L established by the EPA. According to the control variables pH, conductivity and turbidity, it was evident that the Ekofil filter was the one most in accord with what was established by Colombian regulations (Resolution 2115 of 2007) with a removal of 95.4%. Both systems of potabilization provide safe water in order to supply rural communities that do not have water treatment systems.
