Material Separation NF Membrane is primarily used in the separation of monovalent salt and divalent salt, as well as in hardness removal, denitration separation and concentration of liquid, with the molecular weight cutoff covering 200~800 Dal.

MASE-SL is designed to reject the multi-valent ions and organics while allowing the permeation of monovalent ions, and is applicable to purification, decolorization and organism rejection of high-concentrated saline water.


* The use of patented Uarc water distribution endcap ensures more even distribution of hydraulic load on the end surface, thus reducing the accumulation of pollutants.


* The use of brand-new LD (low pressure difference) 34-mil feed channel spacer improves the fouling resistance while reducing the energy consumption.


* The end cap adopts thermal-melt spin welding technology to enhance the structural strength of the membrane element and ensure stable operation of the membrane element under a high pressure difference environment.


* The use of hi-precision spiral-winding technology and low permeate resistance structure decrease the overall fouling rate of membrane element, thus maximizing the working efficiency of membrane element and effectively reducing the operational costs.
