ABSTRACT
 

Currently,  natural occurring arsenic has contaminated groundwater in some countries. Many studies have been conducted to remove arsenic from groundwater.  Treatment methods have been developed  that range from simple to complex. However, simple,  affordable and sustainable methods are in urgent need in many parts of the world like Bangladesh and India, where many people live in poverty.

Zero valent iron (elementary iron) can be oxidized both aerobically and anaerobically in the groundwater system and provides electrons for the reduction of redox sensitive species such as arsenic. Using this simple mechanism, this research project will try to design a simple filter by iron and sand as the filter media to remove arsenic as these materials will be used to reduce inorganic arsenic species to iron co-precipitates.

This project will give more emphasis on laboratory experiments to evaluate performance of the proposed filter.
