Technologies for Removal Of Arsenic From Water: An Overview

Arsenic contamination in drinking water is a major global issue. Arsenicosis may be caused due to chronic consumption of arsenic contaminated water. Economic and convenient removal of arsenic from water has remained a terrific challenge. Most commonly employed technologies for arsenic removal from water are coagulation and flocculation, filtration, membrane separation, ion exchange, adsorption to name a few. Nanotechnology has potential to play an important role in providing clean water for human utilization. Solar oxidation and removal of arsenic (SORAS) is a very simple technique to bring down arsenic content from the contaminated water.
