Juntai Nanofiltration membrane for separation and concentration

Juntai Series of nanofiltration membranes are specially developed for the material concentration and separation fields. They are suitable for industries such as salt mine recycling, zero discharge of high saltwater, material separation, and purification.
JuntaiF1 series: it has a high removal rate of total organic carbon (TOC) and a medium rejection rate of inorganic salts. It is embedded with ultralow pressure and pollution-resistant membrane preparation technology to realize the double Improvement of service life and operation energy consumption cutdown in the field of advanced treatment of wastewater. JuntaiF2 series: high rejection rate for multivalent ions, a low rejection rate for monovalent ions, accurate molecular weight interception, and also suitable for the separation and purification of small molecule pharmaceutical drugs. A special grid design is adopted in the inlet channel, which makes the product more obvious advantages in pollution resistance and easy cleaning.
