Process Description For Ultra Filtration



UF System Capacity 1000 LPH


Ultrafiltration is a membrane process in which a porous membrane is used to separate or reject bacteria, viruses, and large organic molecules, colloidal and particulate matter. Similar to other membrane processes, ultrafiltration is a pressure driven process. High permeability of the ultra filtration membranes and negligible osmotic effects allow the ultra filtration process to operate at relatively low pressures. Typical ultrafiltration modules incorporate capillary or hollow fiber as the membrane structure. The benefit of this type of construction is that it allows for backwashing of the membrane when the filtrate or product flow rate has decreased due to accumulation of material on the membrane side.


The ultrafiltration process can be operated “dead-end” or direct flow, which is 100% conversion of the feed fluid to filtrate, and crossflow.
