NF Membrane 4040 Nanofiltration Membrane Water Treatment Membrane For Water Filtration System

1. When PH is above 10, the Maximum Temperature of Continuous Operation is 35ºC.
2. Under certain conditions, the presence of free chlorine and other oxidants in the water may cause serious membrane damage, which doesn't belong to product warranty range.

Nanofiltration membranes are between reverse osmosis and ultrafiltration membranes, and the separation skin layer on the membrane surface may have a nano-scale microporous structure. Compared with the reverse osmosis membrane, the NaCI removal rate is above 95%. Generally, a membrane with a NaCI removal rate below 90% can be called a nanofiltration membrane. Reverse osmosis membranes have high removal rates for almost all solutes, while nanofiltration membranes only have removal rates for specific solutes. The pore size of the nanofiltration membrane is more than 1 nm, generally 1 to 2 nm. It mainly removes solute particles about one nanometer, and the molecular weight cut off is 200-1000 Daltons. Almost all reverse osmosis membranes are made of polyamide, while nanofiltration membrane materials can be made of various materials, such as cellulose acetate, cellulose acetate-triacetate, sulfonated polysulfone, sulfonated polyethersulfone, aromatic polyamide composites and Inorganic materials, etc. Generally, a polymer electrolyte is formed on the surface of the nanofiltration membrane, so it often has a strong negative charge.
