Abstract

The objective of the study was to evaluate home filters to remove arsenic present in waters coming from the Sama river. The system consisted of a traditional sand filter and a filter with the adsorbent zerovalent iron material stabilized in quitosan. The evaluation of the system lasted for a period of 12 weeks in 18 points of usage; the first eight weeks the arsenic concentration of the filtered water was determined using reactive strips, and the last four assessment was made through atomic absorption spectrometry (AAS). During the first eight weeks the arsenic concentration was reduced in a range of 0.005 and 0.025 mg/L, and during the last four weeks in the range of 0.001 and 0.052 mg/L, from an average concentration of 0.51 mg/L. This research showed that the filtration system is efficient to remove arsenic to natural conditions
