Sistema de tratamiento, depuración y reutilización del agua en zonas rurales, con la tecnología de biofiltración

Abstract

Abstract: It presents the design of a system of treatment, purification and reuse of water, with biofiltration technology to rural areas, which do not have a source of stable water supply or a methodology for debugging it, for the treatment of water is built five test devices with three phases, distinguished by the material of support, the first phase is formed by biological aired filters of ascendant flow constituted by spheres of clay with shell of rice, coffee, peanut and sawdust; the second phase is of descending flow and employs as filtering material sand siliceous to finally circulate by activated carbon filters; for the debugging of grey water is built a biological aired filter of ascendant flow composed by spheres of clay with shell of rice. Periodically, it is registered the data of temperature, pH, total dissolved solids, dissolved oxygen, bacteriological parameters as coliforms total and Escherichia Coli, indicators that help to assess the efficiency of the system. For the treatment system, those biological aired filters, in the fourth month of operation, they present an effectiveness of 90%, while the slow filters of sand, in the third month of operation present an effectiveness of the 100%; the purification system, in the second month of operation retains the 99% of microorganisms pathogenic.
