摘要
This study looked at two arsenic removal technologies, method Bucket Treatment Unit and removal using citrus lime, lemon and filter. The method Bucket Treatment Unit used zero-valent iron and removal using citrus lime, lemon and filter used photochemical oxidation of arsenic. The citrus lime, lemon and filter setup was found to be ineffective with its current design. The results reviewed that the method Bucket Treatment Unit was more effective and appropriate, but with clogging problems. The method Bucket Treatment Unit had between 68% and 100% arsenic removal efficiency with a 36 L/day flow rate of filtrate. The removal using photochemical oxidation of arsenic only had 8% removal efficiency. The Study also reviewed that groundwater resources in the Ashanti Region of Ghana were contaminated with arsenic above the World Health Organization (WHO) standards.
