Ultrafiltration is a pressure-activated membrane filtering process used to separate and/or purify dissolved or suspended particles.
The ultrafiltration membranes are porous and are generally rigid and highly permeated.
The permeation capacity is mainly based on the size of the particle and is therefore similar to that of a screen or sift.
It woks in the same way as reverse osmosis.
A permeate and a concentrate will therefore be produced.
Both may be re-utilised, depending on the applications.

Not only are the ultrafiltration membranes capable of concentrating the macromolecules but they can also be utilised to purify or fraction solutions of micro or macromolecules, likewise for solutions of micromolecules and suspended matter.
Sugar for example can be readily separated from the solutions of macromolecules and suspended matter using an ultrafiltration membrane.
They are also used in the concentration of yoghurt and milk and also in the specific cheese-making sector. In waste water they are used to purify acid or basic baths for their re-utilisation, to recover brines, flexographic inks in the printing processes, to separate oil from water and so on.
