Hydrophilic MembraneFilter Water Harmful Substances

  Non-hydrophilic ultrafiltration membrane, in the mass transfer process of colloid, oil, protein and other pollutants into a cake-like surface attached to the membrane, through a simple backwash difficult to clean non-hydrophilic film operating pressure And the chemical cleaning frequency is high; non-hydrophilic ultrafiltration membrane chemical cleaning cycle is short, each chemical wash cycle backwash after the flux recovery is only 80-90%.

  In the process of mass transfer, colloid, oil, protein and other pollutants in the membrane surface agglomerate into a spherical shape, this spherical aggregates, it is easy to detach from the membrane surface, through a simple anti- Wash the clean hydrophilic membrane can be cleaned and the chemical cleaning frequency is low. Hydrophilic ultrafiltration membrane chemical cleaning cycle is relatively long, chemical cleaning recovery is better, in each chemical cleaning cycle, backwash after the flux recovery close to 100%; hydrophilic membrane is a kind of ultrafiltration membrane, you can filter The water is part of the harmful substances, the membrane can be filtered under a very small pressure of water. Non-hydrophilic ultrafiltration membrane, in the filtration of the mass transfer process, colloid, oil, protein and other pollutants into a cake-like surface attached to the membrane , Through a simple backwash is difficult to clean, non-hydrophilic membrane operating pressure and chemical cleaning frequency is high; and hydrophilic ultrafiltration membrane in the mass transfer process, colloid, oil, protein and other pollutants in the membrane Surface agglomerated into a spherical shape, this spherical agglomerate, it is easy to detach from the membrane surface, through a simple backwash can be cleaned, hydrophilic ultrafiltration membrane operating pressure is low and chemical cleaning frequency.

  Hydrophilic ultrafiltration membrane chemical cleaning cycle is relatively long, chemical cleaning recovery is better, in each chemical cleaning cycle, backwash after the flux recovery close to 100%; non-hydrophilic ultrafiltration membrane chemical cleaning cycle is short, The flow rate of backwash after each chemical cleaning cycle is only 80-90%; so in the water treatment project, the hydrophilic ultrafiltration membrane than non-hydrophilic ultrafiltration membrane has obvious advantages, Life, very well maintained in a stable flow - design flow.
