Hydro-Air - Nanofiltration & Reverse Osmosis Systems

Nanofiltration is a pressure driven process similar to Reverse Osmosis (RO) applied in the area between RO and UF. Monovalent ions and low molecular weight organics are passing through the membrane, while bigger compounds are rejected. MW cut off of a NF membrane is in the range 150-500 and typical application is in pharmaceutical preparations, removal of colour, of hardness from water.
