Composition for arsenic removal from ground water

摘要

The present invention provides a process for removing arsenic from ground water to be processed and used in remote dwellings. The process includes (a) contacting a clay, a coagulant, and an oxidizer with water containing arsenic to form a coagulated colloidal mixture; (b) adsorbing the arsenic onto the coagulated colloidal mixture; and (c) separating the water from the coagulated colloidal mixture. The invention also provides a composition ready for use in removing arsenic from ground water to be used in remote areas. The composition includes an activated clay, a coagulant, and an oxidizer in predetermined proportions for efficient removal of arsenic from ground water.
