Abstrakt: The goal of this study was to recover of phenolic compounds from pomegranate peels (Cortex Granati fructuum) with high yield by sequential processes of water base extraction and ultrafiltration (UF). The effects of transmembrane pressure (TMP), process temperature (T) and initial total phenolic content (TPC) of feed on UF performance were modelled by Box-Behnken method. The optimum conditions were TPC of feed of 524 mg gallic acid L−1 extract, T of 37 °C and TMP of 150 kPa providing the maximum 8.5-fold increase in TPC and the acceptable 20% decrease in initial permeate flux. The TMP was the most significant parameter affecting the solute rejection and the membrane fouling. Increase in the TMP caused to threefold increase in the cake layer resistance while the irreversible fouling resistances were negligible for all the operations. As a result, the UF process through the extremely hydrophilic membrane provided efficient phenolic recovery with membrane fouling at a reasonable level can serve more profit-making process to the industry.
