RO Membrane Keensen SW8040

RO Membrane Keensen SW8040
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.
