Tratamiento de agua mediante plantas piloto para el sector rural, aplicando tecnologías de biofiltración. Caso de estudio: utilizando carbón activado y arcillas.

Abstract

Abstract:The technologies through the use of a biological aerated filters system (FAB), have been proposed as a viable alternative for the treatment of rainwater in the rural sector. The Biofiltration develops in porous media (activated carbon, clays); with the capacity to form a biofilm on the surface, which helps eliminate physical and chemical substances present in water. This research aims to evaluate three biofilters constituted with different filtering material such as activated carbon (CA), and clay spheres (ACAL / ACAR), to determine the efficiency of biofilters in terms of the elimination capacity of microorganisms and heavy metals in water. The physical and chemical parameters analyzed during a period of six months were: temperature, pH, STD, OD, aluminum, calcium, copper, iron, magnesium, manganese, plumbum and zinc. The results showed that biofilters show good efficiency in the reduction of aluminum, copper, manganese and zinc, while, in terms of elimination of calcium, iron, magnesium and plumbum are not feasible.
