Cross-Flow Filtration

The type of cross-flow membrane filtration depends on the individual product to be treated.

Reverse Osmosis (RO)	Retains micro-/macromolecules, viruses, bacteria, colloids, suspended solids. Filtration range: 0.0001-0.001 µm Pressure: 20-80 bar MWCO < 200
Ultrafiltration (UF)	Retains macromolecules, viruses, bacteria, colloids, suspended solids. Filtration range: 0.002-0.1 µm Pressure: 1-10 bar MWCO 2,000-500,000
Nanofiltration (NF)	Retains micro-/macromolecules, viruses, bacteria, colloids, suspended solids. Permeates: monovalent salts Filtration range: 0.0005-0.01 µm Pressure: 20-40 bar MWCO 200-500
Microfiltration (MF)	Retains viruses, bacteria, colloids, suspended solids. Filtration range: 0.1-10 µm Pressure: 0.2-2 bar MWCO > 1,000,000
