Research Brief 83: Removal of Arsenic from Domestic Drinking

2001/11/7For all environmentally relevant concentrations of arsenic (i.e., 5,000 mg/L), the canisters removed arsenate to below the detection limit of 1 mg/L. The researchers determined that the kinetics of the arsenate removal process are sufficiently fast to be employed in both small and large-scale treatment systems using hydraulic residence times less than 1 minute.

Arsenic control

2012/11/15Arsenic control. Groundwater contamination by arsenic has been a major concern across the globe. In India, this highly toxic chemical exists in natural form in Uttar Pradesh, Bihar, Jharkhand, West Bengal and Assam. Exposure to it can cause discolouration of skin, warts and even death. India has, however, been slow in tackling the problem.
