Remediation Methods

A
rsenic contamination in ground water contamination is a serious problem as it
is acute toxic. Ground water of many parts of the world are being contaminated
by arsenic. Therefore, the development of arsenic treatment and remediation
technologies is required urgently. The physical (ion exchange, reverse osmosis,
electrokinetics, adsorption), chemical (coagulation and sedimentation, lime softening,
oxidation) and biological (bacterial oxidation, phytoremediation) treatment methods
are available for the removal of arsenic from the ground water. The units developed
and used at commercial scale include different kinds of filters, bucket type units,
fill and draw, kalshi etc. The remediation methods discussed include air oxidation,
reactive barriers, utilization of deeper aquifers and sanitary protected dug wells.
But still no technology is available which can be used for the removal of arsenic
from the ground water at economic, efficient and commercial levels affordable in the
developing and under developed countries (especially Bangladesh, India and other
effected countries). Further improvements are required to develop fast, efficient and
economic arsenic removal technologies.
