Ultrafiltration
Ultrafiltration membrane systems retain particles, bacteria, protozoa, viruses and organic molecules greater than their related molecular weight cut-off. Ultrafiltration thus removes large organics such as proteins, pyrogens, bacteria and colloids, but does not remove dissolved substances or change the chemical characteristics of water.
Ultrafiltration is widely used in the fractionation of milk and whey, and in protein fractionation. It concentrates suspended solids and solutes of molecular weight greater than 1,000. The permeate has low-molecular-weight organic solutes and salts.

Benefits:
- High tolerance of suspended solids
- Smooth surface retards bacterial growth and fouling
- Tight membrane structure avoids penetration of bacteria and wide range of colloidal and suspended material
- Microporous regions ensure low differential pressure and enhanced flow rate
- Low recirculation flow rates reduce power consumption
- Fully automated system ensures consistent and reliable flux, predictable performance and minimal maintenance
