Nanofiltration Membrane Testing

Nanofiltration membrane is a functional semipermeable membrane that allows solvent molecules or certain low molecular weight solutes or low-valent ions to pass through. Its molecular weight cutoff is between reverse osmosis membrane and ultrafiltration membrane, about 100-2000Da. It is speculated that the nanofiltration membrane may have a microporous structure of about 1nm, so it is called "nanofiltration". This type of filtration is primarily used for water treatment and is capable of removing a significant percentage of organics, viruses, bacteria, and other particulates.

The results of the nanofiltration membrane tests can help engineers to select the right membrane for their application and to optimize the operation parameters like operating pressure, cross-flow velocity, and recovery rate. It is recommended to perform these types of testing regularly to ensure the performance and reliability of the filtration system.

STEMart provides comprehensive and reliable nanofiltration membrane testing services to guarantee the performance and durability of a nanofiltration system, and guide decisions with regard to maintenance, repair, or replacement of the membranes, ensuring the long-term success of the nanofiltration system.
