Technologies for Arsenic Removal from Water: Current Status and Future Perspectives

Abstract: This review paper presents an overview of the available technologies used nowadays for the removal of arsenic species from water. Conventionally applied techniques to remove arsenic species include oxidation, coagulation-flocculation, and membrane techniques. Besides, progress has recently been made on the utility of various nanoparticles for the remediation of contaminated water. A critical analysis of the most widely investigated nanoparticles is presented and promising future research on novel porous materi… Show more

“…Traditional remediation techniques such as coagulation, precipitation, ion exchange, and membrane separation are available to remove arsenic from water [6][7][8][9]. However, most of them present major disadvantages with incomplete metal recovery, high capital and operation costs, and/or sludge disposal problems [10].…”

“…It is known to be highly toxic to all life forms [3] and has been classified by the World Health Organization (WHO) as a group 1 human carcinogenic substance [4]. Consequently, its removal from water is a widely studied important issue for producing drinking water [5]. Among these removal processes adsorption techniques are generally preferred due to the possible regeneration and therefore the reuse of the solid phase.…”

“…Iron release from metal pipes could be one of the sources of iron in DWDSs [11,22]. Meanwhile, the use of iron flocculants during water treatment was also found to be a source of iron [23,24]. As a result, the PVC-U pipes could be considered as a source of secondary iron pollution, thus affecting drinking water quality.…”
