The effluent samples were collected from selected manufacturing units established nearby Gwalior, Madhya Pradesh, India. The study found that COD and heavy metals namely Fe, Cr, Pb and Zn were present in the sample and their concentration exceeds the permissible limit sometimes as prescribed by BIS. These pollutants cause serious health problems in human beings when they enter through food chain. Therefore, to minimize health problems, the effluent treatment using Neem leaf adsorbent was done. The percentage removal depends on the factors like pH, conc. of pollutants, amount and particle size of adsorbent, contact time etc. The maximum COD removal was observed up to 68.66 %, whereas the maximum removal of Fe, Cr, Pb and Zn was observed up to 60 %, 48.48 %, 63.72 % and 59.13 % respectively. The findings before and after the adsorption treatment indicate that the pollution level minimized considerably when compared to the permissible limit of BIS.
