It is applicable to the desalination of raw water with salt concentration between 15000ppm and 40000ppm, and make removal for the boron is more than 90%. This membrane model was widely applied to the desalination of sea water and high concentration brackish water, concentration and recycle treatment for high salt wastewater.
