Water multi-step treatments to remove arsenic already exist, using filtration (adsorption), but this process requires pre-treatment (oxidation) to be efficient .

You may come across the issue of arsenic speciation if you are choosing a water treatment system. Arsenic speciation is identifying which type of arsenic is in your water. Arsenic can exist as trivalent arsenic (also called arsenic 3) or pentavalent arsenic (also called arsenic 5). Trivalent arsenic is the most toxic form, and it is the common ...

Arsenic is a major toxic contaminant that represents a human health concern by impairing water quality on a global scale (Nordstrom 2002; Smedley and Kinniburgh 2002).The inorganic arsenic species are predominant in aqueous environments, and their variation dynamics rely mainly on pH and redox potential.

Treatment of public water supplies. For public water supplies, the main methods of treatment are precipitation, adsorption or ion exchange. Chemical precipitation (as opposed to rain or snow!) occurs when the concentration of a salt in solution is higher than its solubility limit. Crystals begin to form and the chemical "crashes" out of ...
