The problem of wastewater with high content of salt is a frequent problem for the environmental authorities, because the existing municipal and industrial wastewater treatments are incapable to remove effectively inorganic compounds. In this paper an attempt was made to report new results with reverse osmosis (RO) and nano-filtration (NF) membranes to remove salts from fermentation wastewater.The basic target of the experiments was to find an industrial membrane, which can separate salts from fermentation wastewater with a high efficiency and the concentration of the clean water should satisfy the environmental regulation: salt concentration ≤ 2500 mg/L and COD concentration ≤ 1200 mgO 2 /L. RO process exhibited good salt rejection and effective removal of organics. The other aim of this study was to model the osmotic pressure and permeate flux in the wastewater using basic expressions, like van’t Hoff law and Rautenbach equations. The combination of the above models with experiment based constants gave a good tool for modeling salty wastewater.
