Assessment and Comparison of Techniques for Eliminating Arsenic from Potable Water

Arsenic is the third element in group ۵ of the periodic table. It is used in various industries, including agriculture, animal husbandry, medicine, electronics, industry, and metallurgy. Arsenic is highly carcinogenic and can cause skin, lung, bladder, and kidney cancer. In regions where drinking water contains high levels of arsenic, it presents a serious health risk, and immediate action should be taken. In recent years, a variety of technologies have been developed to remove or reduce arsenic levels in drinking water. These technologies range from conventional methods to newer approaches such as coagulation (flocculation), iron and manganese precipitation and filtration, lime treatment, activated alumina, oxide-coated substrates, ion exchange, membrane purification, and reverse electrolysis systems like reverse osmosis. Each removal process has its own set of advantages and disadvantages, which will be described and discussed in this study.
