Removal of Chromium From Groundwater using Neem Leaves as Adsorbent

The effluents of tannery industries are the major source of chromium contamination in the groundwater. In most of the sub-urban areas ground water is the major source of drinking water. For human being Long term exposure to chromium is detrimental. The main objective of this study is to assess the groundwater contamination and to adopt appropriate methods and to develop suitable techniques either to prevent chromium contamination or to reduce it to very low levels with due consideration to cost optimization. Bore well samples were collected from 6 location from the proximity of tannery industry at a distance of 25m interval and at different depth during 2014 in the month of March. To remove the chromium from the groundwater neem leaves is used as the adsorbent. The column study was conducted to determine the effect of adsorbent to remove the chromium concentration from the ground water. To investigate the influences of bed height on the performance of chromium adsorption on to the neem leaves in a fixed-bed column. The results reveal that the concentration of chromium is high near the tannery industry in Chrompet so the study concluded that usage of groundwater in Chrompet should be avoided.
