●FFM Inc Series nanofiltration membrane has a strong selective rejection effect, and its rejection ability for different valence ions is very different, reflecting the very high selective transmission performance of the nanofiltration membrane. ●Series nanofiltration membrane can not only be used to soften the water quality of municipal tap water, groundwater, surface water, industrial wastewater and other water systems, but also be used to separate complex materials, widely used in the separation and concentration of food, medicine and other industries.
