Sanitary Nanofiltration Membrane
Product Description
- Sanitary nanofiltration membranes are designed to deliver selective separation of dissolved components, enabling efficient removal of multivalent ions and organic molecules while allowing controlled passage of monovalent salts.
- Positioned between ultrafiltration and reverse osmosis, the membrane provides an optimized balance between permeability and selectivity, supporting applications that require both purification and retention of valuable constituents.
- With relatively low operating pressure and energy demand, nanofiltration offers a cost-effective solution for softening, organic removal, and partial desalination in hygienic processing environments.
Product Features
- Optimized polyamide membrane layer enhances salt rejection and flux stability
- Improved anti-fouling characteristics ensure longer service life
- Parallel flow channel design enables better cleaning efficiency
- Compatible with a wide pH cleaning range for flexible operation
