The aim of this project was to study sand filters as a low cost method in the post treatment of upflow anaerobic filter effluent, fed by municipal wastewater. This research intends to contribute with the development of this system estimating the efficiency of the treatment of four sand filters with different depths of the sand layer (0,25; 0,50, 0,75 e 1,00 m). The feed (I think it's influent) was from the four upflow anaerobic filters. Five hydraulic loads (20, 40, 60, 80 e 100 Lm-2) were used to apply the effluent on the sand filters. Each one was applied for one month and later the frequency was increased for two and tree times per day. The municipal wastewater, influent and the effluent of the sand filter were weekly analyzed allowing to conclude that the treatment system had good removal of BOD, COD, TOC, nutrients and microorganisms like total and fecal coli forms. The effluent was good to be disposed or to reused (AU)
