The properties and life cycle of the hydrophilic film


Characteristics

Non-hydrophilic ultrafiltration membrane, in the process of mass transfer, 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 High and high frequency of chemical cleaning;

The hydrophobic ultrafiltration membrane in the filtration of the mass transfer process, 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 can be clean, hydrophilic ultrafiltration membrane operating pressure is low and chemical cleaning frequency is low.


Use cycle

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
