Arsenic Removal Systems

The most prevalent forms of arsenic found in groundwater are the pentavalent arsenate ion (As[V]) and the trivalent arsenite ion (AS[III]). As[III] is easily oxidized to As[V] with chlorine and other oxidants, Ferric chloride reacts with water and forms Fe(OH)3, which strongly adsorbs the As[V]. In some ground water supplies there is enough naturally occurring iron that only chlorine needs to be added to precipitate the arsenic. Where natural iron is not present in high enough concentrations, additional iron must be added in a form such as ferric chloride to ensure there is adequate adsportion of the As[V].
