The purpose of this paper is to design a novel module for the removal of arsenic (As) in drinking water. The main removal mechanism of the proposed device consists on adsorption on geomaterial. Adsorptive material is a granular media from Sierras Chicas in Cordoba Province, Argentine. Design of the removal device is based on previous batch and soil column tests performed to evaluate the capability of this material for the removal of As from water. The removal efficiency ranged from 12% to 92% depending on the initial As concentration and flow rate. Obtained results show that the developed filters successfully reduced As concentration in drinking water during more than 100 days.
