Ultrafiltration is widely used in industry as pre-treatment for other forms of purification
such as ion exchange and reverse osmosis. Hollow fiber configuration is widely used in the ultrafiltration processes. The benefit of this construction is that it allows for the backwashing of the membrane when the filtrate or product flow rate has decreased due to the accumulation of material on the membrane. The ultrafiltration membrane is capable of removing colloidal materials, fine suspensions, bacteria, viruses, suspended material, and large dissolved molecular weight organic materials.
