Implementación de un Filtro Lento de Arena para Mejorar la Calidad de Agua en la Escuela Comunitaria Fiscal Chimborazo

Abstract

The implementation of appropriate technologies for the purification of water in rural areas has become today a usual practice in developing countries, among which are the slow sand filters. In the present work, the construction, operation and maintenance of a slow sand filter is detailed, as well as a chlorination system through the use of a chlorine doser due to erosion. The filter treats a flow rate of 0.06 (l / s) with a filtration rate of 2(m3/m2 *day). The proposed treatment of filtration and disinfection has a removal efficiency in parameters that were not within the maximum permissible limits for water for human consumption, which are: 100% total coliforms, 100% fecal coliforms, 76% apparent color, total iron 77%, total solids 24% and turbidity 80%, it is important to mention that the removal efficiency increased after the maturation period of the biological layer in the SSF. Finally, the use of this alternative treatment at home is recommended for rural areas where there is no potable water system.
