Abstract

In the present work, the efficiency of colloid-enhanced ultrafiltration (CEUF) of canola oil miscella was investigated using an anionic surfactant (sodium dodecyl sulfate salt [SDS]), chelating agent (ethylenediaminetetraaceticacid [EDTA]), salt (calcium chloride [CaCl2]) and two molecular weight cutoffs of hydrophobic (polyvinylidene fluoride) membranes (50 and 100 kDa). There were thicker fouled layer on both membrane surfaces for SDS- and EDTA-pretreated samples. The flux reduction of M116 membrane was more than M183 membrane with the all samples except SDS added ones. It was observed that CEUF of EDTA- and SDS-pretreated samples exhibited high efficiency in removing phosphorus. Increasing temperature from 25 to 55C improved the steady-state permeate flux of SDS-pretreated samples to extent of 13 kg/m2h. Furthermore, increasing pressure led to increase the permeate flux of pretreated sample except CaCl2 adding ones.
