Removal of ChromiumFromGroundwater using NeemLeaves asAdsorbent

Abstract

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