Introduction to NF RO Membrane
Nanofiltration (NF) and Reverse Osmosis (RO) membranes are crucial components in advanced water treatment technologies. NF membranes are designed to separate dissolved substances based on their molecular size and charge. They can reject most organic molecules with a molecular weight between 200 - 1000 Daltons, as well as divalent and multivalent ions, while allowing monovalent ions and small molecules to pass through to some extent. RO membranes, on the other hand, are more restrictive. They can reject almost all dissolved salts, organic compounds, and microorganisms, producing high - purity water. These membranes are widely used in various industries such as desalination of seawater and brackish water, purification of drinking water, wastewater treatment and reuse, and in the food and pharmaceutical industries for product concentration and purification.
