2. Iron oxide adsorption - Wikipedia

   en.wikipedia.org/wiki/Iron_oxide_adsorption

   Arsenic is a common natural contaminant of well water and is highly carcinogenic. Iron oxide adsorption treatment for arsenic in groundwater is a commonly practiced removal process which involves the chemical treatment of arsenic species such that they adsorb onto iron oxides and create larger particles that may be filtered out of the water stream.

3. Arsenic contamination of groundwater - Wikipedia

   en.wikipedia.org/wiki/Arsenic_contamination_of...

   In subterranean arsenic removal, aerated groundwater is recharged back into the aquifer to create an oxidation zone which can trap iron and arsenic on the soil particles through adsorption process. The oxidation zone created by aerated water boosts the activity of the arsenic-oxidizing microorganisms which can oxidize arsenic from +3 to +5 ...

   en.wikipedia.org/wiki/Sono_arsenic_filter

   The Sono arsenic filter was invented in 2006 by Abul Hussam, who is a chemistry professor at George Mason University (GMU) in Fairfax, Virginia. It was developed to deal with the problem of arsenic contamination of groundwater . [ 1 ]

5. Portable water purification - Wikipedia

   en.wikipedia.org/wiki/Portable_water_purification

   Groundwater pollution may occur from human activity (e.g. on-site sanitation systems or mining) or might be naturally occurring (e.g. from arsenic in some regions of India and Bangladesh). Water collected as far upstream as possible above all known or anticipated risks of pollution poses the lowest risk of contamination and is best suited to ...

6. Arsenic poisoning - Wikipedia

   en.wikipedia.org/wiki/Arsenic_poisoning

   Arsenic removal technologies are traditional treatment processes which have been tailored to improve removal of arsenic from drinking water. Although some of the removal processes, such as precipitative processes, adsorption processes, ion exchange processes, and separation (membrane) processes, may be technically feasible, their cost may be ...
