During the mass transfer process of hydrophilic membrane filtration, colloids, oils, proteins and other pollutants agglomerate into spheres on the membrane surface. Such spherical agglomerates are easily separated from the membrane surface and can be cleaned by simple backwashing. The operating pressure of hydrophilic membrane is low and the frequency of chemical cleaning is low.
The chemical cleaning cycle of hydrophilic ultrafiltration membrane is longer, and the chemical cleaning recovery is better. In each chemical cleaning cycle, the flux recovery after backwashing is close to 100%. The chemical cleaning cycle of non-hydrophilic ultrafiltration membrane is short, and the flux recovery after backwashing within each chemical cleaning cycle is only 80-90%. Therefore, hydrophilic ultrafiltration membrane has obvious advantages over non-hydrophilic ultrafiltration membrane in water treatment engineering, which can maintain a stable flow rate in its service life.
The hydrophilic membrane is a kind of proprietary technology, manufacture new material - it USES a variety of polymer materials and different fillers, according to the needs of the target after different compatibility, through the special processing process of sintering becomes - is the pp cotton, ceramic filter and hollow fiber membrane, filter out suspended solids in water with pure physical methods and new filter material toxic and harmful substances; According to different environment and requirements, the filtration accuracy can be selected between 5 and 0.01 micron, which can be widely used in various water treatment fields.
