The research work was carried out in l. E N°. 00813, located in Ochame town, Moyobamba district, Moyobamba province, San Martin department, taking as its objective to determine the effect the physical filters in the treatment of domestic wastewater for reuse in irrigation, considering the physical, chemical and bacteriological parameters of the residual water (pH, 0805, OQO, SST and Total coliforms), the same who were compared with the Environmental Quality Standards (ECA) laid down in the national standards. The literature review led to assume that if we use physical filters in the treatment of domestic wastewater, then we would get useable water in irrigation, which formed the research hypotheses. In the operative part, research was conducted under an experimental design with pre- and post-test, and during the period of operation of the filters were six physical samples of wastewater;...
