    <description descriptionType="Abstract">The aim of this study was to improve ultrafiltration (UF) performance during clarification of raw apple juice through surface modification of commercial polysulfone membranes (US100) by low-pressure oxygen plasma treatment (LP-OPlsT). A Plasma power of 90 W and exposure time of 10 min were determined as the most effective parameters enabling an increase in the Delta G(iwi) value of the plain membrane from (-) 25 +/- 2 mN m(-1) to (+) 30 +/- 1 mN m(-1). Improved hydrophilicity achieved by LP-OPlsT remarkably enhanced the performance of US100 throughout the clarification of raw apple juice without the need of an additional pre-flocculation step. While R-frev (86%) was the dominant resistance controlling the fouling during UF of raw apple juice through the plain membrane, the contribution of R-frev to R-t decreased to 56% after pre-flocculation step. LP-OPlsT further decreased this ratio, up to 46%, confirming the charge repulsion between the modified membrane and the foulant particles.</description>
