Polyethersulfone polymer membranes, particularly when modified to become water-attracting, offer notable enhancements in separation performance. The natural hydrophobicity regarding standard PES results in limited wetting and resulting reduced flow rate in aqueous processes. Exterior modification via hydrophilization – typically involving grafting resin chains or introducing reactive groups – drastically boosts the membrane’s affinity for water, leading to decreased pressure drops, improved flow and enhanced overall performance across a wider range of aqueous systems. This produces improved performance in diverse fields like fermentation and water processing.
