One of the major drawbacks for the successful of Ultrafiltration (UF) during pretreatment of glycerin-rich solution is membrane fouling due to the deposition of Triglycerides (TG) and Fatty Acids (FA). The aim of the present study is to contribute to the better understanding of fouling by TG as well as TG-FA mixtures and their adsorption properties on UF membrane. Additionally, another significant part of this study was the elucidation of the solute-solute interaction in the feed solution. Two UF membranes were used with the membrane materials made from Polyethersulfone (PES) and Polyvinylidenefluoride (PVDF) with MWCO between 5, 20 and 25 kDa for PES, while 30 kDa for PVDF. Static adsorption of TG and TG-FA were investigated at the solution pH values of 3, 7 and 10; for different MWCO.
