About this document
Chromium Removal Case Study Analysis by jayprakash nage is a document available to read on EtoBox.
The document describes a case study of removing excess chromium from water. It discusses that hexavalent chromium is toxic while trivalent chromium is not. The proposed method is chemical precipitation using sodium metabisulfite to reduce hexavalent to trivalent chromium, followed by precipitation of trivalent chromium using calcium hydroxide and sodium hydroxide. This method produces less sludge than alternatives and maintains pH, removing over 95% of total chromium cost-effectively.
