23 Technologies for arsenic removal from groundwater

2010-11-12  The technologies for removal of arsenic are based on one or a combination of several physical-chemical processes. The five common types of treatment are summarised below: Oxidation: Arsenic in groundwater may occur as arsenite, As(III), and arsenate, As(V), in different proportions. Most arsenic treatment technologies are very effective in removing

Arsenic removal technologies and future trends: A

2021-1-1  The most promising technologies for the selective removal of arsenic from contaminated water have been nanofiltration and reverse osmosis (Figoli et al., 2016). The driving force in NF and RO is achieved by pressing the feed side to allow water to percolate via hydrophilic membrane and thus remove the required contaminants like arsenic.

Arsenic Removal from Drinking Water: Experiences

Treatment of drinking water for arsenic (As) removal has been implemented in centralized facilities worldwide, reflecting the increasingly stringent national and international drinking water standards for As, for which a standard of 10 μg / L has been widely adopted. It might therefore be expected that information on the performance of installed treatment processes could serve as basis for process optimization and
