Abstract: This research work introduces an alternative of low cost and easily installable system for treatment of wastewater applied to small communities. These experiments were developed at Experimental Field of Agricultural Engineering College (AEC/UNICAMP). The total volume produced at AEC is 20 m 3 day-1, and half part was treated by modular systems. The first system line (A) is composed by an UASB reactor (Upflow Anaerobic Sludge Blanket) followed by two Anaerobic Filters and the second system (B) line is composed by a kind of reactor called CAR (Compartmented Anaerobic Reactor) and it is followed by two Anaerobic filters too. Both systems were handled from December of 2002 through February of 2004 totalizing 30 sample collections. It was concluded under comparation that both system performances were similar and obtained satisfactory results. Medium grades of efficiency in remotion of sedimentable solids, total suspended solids and CDO (Chemical demand of oxygen) obtained in modular system (A) were 99.58%; 94.33% and 67.30% respectively. Modular system (B) showed a remotion of 99.49%; 93.34% and 70.45% to the same evaluation parameters. Both modular systems demonstrated adequate and viable to promote a sanitary treatment of wastewater produced in small communities.
