Nanofiltration Water Treatment Technology is utilized for removal of particles in a range of 0.01 to 0.001 micron. Similar to Ultrafiltration technology, the scaling needs to be controlled to maintain a high flux rate from the system. The application of this technology has been used in textile industry, and chemical recovery system from plating baths in plating industry.
