Literature Research• Presence of chloride affects COD analysis –resulting in false high COD concentration• Various analytical methods are adapted tocorrect for this interference• New “modified method” shows bettercorrection than others, resulting in 90+percent accuracy• Independent method comparison is ongoing
Literature Research Impact• Unit operations selected are “state of the art”• Influent COD volatiles, insolubles, and solids –physical separation processes treat a highpercentage of influent COD• Soluble COD can be reduced to a concentration ofabout 200 mg/L through biotreatment• Modified analytical method could show actual CODconcentration is lower than previously reported
