Description
This study was carried out to assess the levels of total chromium in the chrome plating wastewater and its removal by chemical precipitation using lime water suspensions. The wastewater produced from chrome electroplating is huge and complex which far exceed the assimilative capacity of nature and lead to an irreversible health and ecological consequence. Wastewater samples are collected from Homicho Ammunition Engineering Industry. The physicochemical analysis and heavy metal concentrations determined for different parameters using FAAS and titration.
