Prototype Experiments Assessing Arsenic and Iron Removal Efficiencies through Adsorption Using Natural Skye Sand

Based on earlier batch and column experimental results, it was established that Skye sand is suitable for removing arsenic from water through adsorption. As a real-size prototype may not always replicate results experiments, this paper presents removal filter using the same used in experiments. arsenic-contaminated often associated with high concentration of iron, which causes blockage system, study also investigates iron media. First, several physical properties were XRF, XRD, SEM EDX analyses. Then, made based an design similar oxide-coated (IOCS). It found current capable consistently to level below detection limit (0.05 µg/L) considerable period (up 150 bed volumes). Additionally, WHO-acceptable (0.3 mg/L). Analytical calculation suggests can produce arsenic-free continuously 600 days (100 L per day) feed 500 µg/L.
