Hollow Fiber Membranes
DescriptionHollow fiber filtration utilizes numerous long porous filaments packed inside a body. Each filament is very narrow in diameter and very flexible. Hollow fiber can find uses in all types of filtration, ranging from microfiltration to reverse osmosis.
How it worksHollow fiber filtration works on the same principle as tubular and capillary filtration, but utilizes a small tube diameter which allows for flexibility.
DisadvantagesIrreversible fouling and easy breakage are the main problems concerning hollow fiber filtration. Because of the flexibility of the fibers, they are more likely to break when under high strain compared to other methods of filtration such as tubular or spiral wound elements.
AdvantagesHollow fiber features very high packing density because of the small strand diameter. Because of the flexibility of the strands, certain filter configurations are possible that cannot be achieved in other filtration configurations.
