The purpose of this research is to determine the efficiency of Vetiver grass as an inorganic arsenic remover in waters determined for human consumption, by assembling a small pilot (treatment unit) and comparing the arsenic concentrations of the tributary and effluent of said pilot. A prliminary design of the research pilot and operating- conditions was established, designating flows of 8; 4; 2 and 1 mL/s associated with retention times of approximately 0,75; 1,50; 3,00 and 6,00 days respectively, thus forming the treatment rounds Nº 1, Nº 2, Nº 3 and Nº 4. The research pilot is composed of two rows (A and B) of four plastic cylinders, where both rows have the same tributary. The cylinders in each row are connected in series and each group houses four groups of Vetiver grass cuttings. The monitoring of each round of treatment was carried out, from the beginning of the operation until the culmination with the sampling of the effluents. The results that obtained the highest arsenic removal are 77,39 % for row A and 98,23 % for row B. Both results were obtained when the pilot operated at 2 mL/s in both rows. In general, the pilot operated better in treatment round Nº 3. Finally, other changes were simulated taking into account the degree of inorganic arsenic removal required and the final design of the pilot, establishing defined operating and maintenance conditions.
