where h is the separation efficiency evaluated in terms of the decrease of the COD. COD u and COD L are the chemical oxygen demand in the underflow and feed flow respectively. The COD was determined by the ,potassium dichromate, method [Greenberg et al., 1992], which is based on the oxidation of organic matter by a boiling mixture of chromic ,acid, and sulfuric ,acid,.
