Membrane Structure

Ultra-filtration membrane cartridges operate from the inside to the outside during filtration. This means that process fluid (retentate) flows through the centre of the hollow fibre and permeate passes through the fibre wall to the outside of the membrane fibre. Tangential flow can help limit membrane fouling. Other operating techniques that can be employed with hollow fibre ultra- filtration membrane systems include back flushing with permeate and retentate reverse flow.
