Industrial wastewater treatment is a hotly discussed topic in the industrial park recently. The country requires continuous development. In order to protect the environment, it requires zero discharge of wastewater. For this reason, ptfe liquid filtration membrane plays a huge role.
Membrane technology is developing rapidly in the field of water treatment. It uses the micropore screening effect of membranes to filter pollutants in water.
Membrane technologies commonly used in advanced treatment of drinking water include microfiltration, ultrafiltration, reverse osmosis and nanofiltration.
Among them, the performance of nanofiltration membrane is between reverse osmosis membrane and ultrafiltration membrane.
The pore size of the nanofiltration membrane is 0.001~0.5μm, the operating pressure is 0.5~1.0MPa, and the separation layer on the surface of the membrane has a nanoscale microporous structure.
Traditional water treatment technology mainly removes suspended solids and colloidal particles in water, but its ability to remove dissolved organic matter in polluted water sources is obviously insufficient, especially the “three-phase” substances formed after chlorine disinfection and their Precursors are even more difficult to process with conventional processing methods.
The PTFE liquid filtration membrane can remove small molecular organic matter with a relative molecular mass of less than 500 in the water. The total salt removal rate is about 90%, and it has a good removal effect on inorganic ions in municipal tap water.
The ptfe liquid filter membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, The filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
