The ultra-low pressure reverse osmosis membrane has the characteristics of high salt rejection, large water flux, strong anti-pollution and anti-bacterial erosion. Due to its special surface structure, the surface potential is neutral and hydrophilic, unlike ordinary reverse osmosis membranes. It is easy to adsorb surface active substances and is blocked by dirt. Therefore, it is a new type of reverse osmosis membrane used in various wastewater treatments. What are the characteristics of ultra low pressure reverse osmosis membrane?

Ultra-low pressure reverse osmosis membrane characteristics, also listed the ultra-low pressure membrane and low pressure CPA2 or NTR-759 membrane and acetate CA membrane in the comparison of operating pressure, permeate water, desalination rate, studied various methods and various anti- The osmotic membrane has a better effect on the removal of TOC and bacterial endotoxin, and has been successfully applied in water for space material preparation, water for high purity reagent production, water for locomotive battery and water for building materials.

Reverse osmosis (RO) is a pressure-driven separation of the solute in the solution from the solvent by means of a selective shut-off of the semi-permeable membrane. The low-pressure composite membrane or the ultra-low pressure composite membrane is the rate of water permeation. The desalination rate is high or low to measure the quality of the membrane, and the water permeation rate, that is, the water flux is proportional to the driving pressure. If a certain water flux is reached, the lower the driving pressure required, the lower the pressure. Energy consumption, while also reducing equipment investment in pumps, pressure vessels and pipes.

The low pressure composite membrane and the ultra low pressure composite membrane have larger specific surface area than the cellulose acetate membrane, low operating pressure, large water production, high desalination and desiliconization rate, saving system operating cost and equipment investment, and ultra low pressure reverse osmosis membrane due to All the advantages of the composite film are maintained. It has good chemical stability. The low pressure composite membrane and ultra low pressure composite membrane are the ideal reverse osmosis membranes for the preparation of high purity water. Compared with the conventional RO membrane, the LF10 membrane has the same high salt rejection rate and high water flux at low pressure. Because of its neutral surface potential and hydrophilicity, it has strong anti-pollution ability, so it has superior performance in wastewater treatment of membrane fouling caused by surface active substances.
