The principle of subsurface arsenic removal (SAR) from groundwater is based on oxidation
and adsorption reactions by infiltrating oxygen into the anoxic aquifer and the immobilization …

The principle of subsurface arsenic (As) removal (SAR) is to extract anoxic groundwater,
aerate it and reinject it. Oxygen in the injected water reacts with iron in the resident …

In Cambodia, groundwater has been contaminated with arsenic, and purification of the water
is an urgent issue. From 2010 to 2012, an international collaborative project between Japan …

An aquifer Fe-coating technology was evaluated for in-situ As remediation. The groundwater
in the aimed aquifer has low dissolved Fe (II) concentration and high As (III) concentration …

The principle of subsurface or in situ iron and arsenic removal is that aerated water is
periodically injected into an anoxic aquifer through a tube well, displacing groundwater …

Arsenic contamination in groundwater is a critical issue and one that raises great concern
around the world as the cause of many negative health impacts on the human body …

An effective and low-cost in-situ geological filtration system was developed to treat arsenic-
contaminated groundwater in remote rural areas. Hangjinhouqi in western Hetao Plain of …

Water treatment residual solids were examined in batch adsorption and column adsorption
experiments using a groundwater from Halifax Regional Municipality that had an average …

The ex-situ treatment of arsenic is widely adopted; however, there are emerging concerns
related to system maintenance, material replacement, and waste generation. There is a …

A high concentration of arsenic in groundwater is a worldwide problem, high concentration
of arsenic in groundwater has been documented as a major health issue around the globe …
