The objective of this work was to verify the efficiency of trickle irrigation filters on the removal of suspended solids using as filter elements three different types of non-woven synthetic fabrics. Also, was conducted an experiment with disk and screen elements in order to compare with the non woven synthetic fabric element. The results have demonstrated that non-woven synthetic fabrics presented better performance, removing 27 to 29% of suspended solids, while screen and disk elements presented 19 to 20% removal. No significant differences were observed among the three fabrics evaluated as well as between the screen and disk elements
