It will not interference in having time.
Herein it should be noted that above-mentioned first cleaning assembly 9, the second cleaning assembly 10 and third cleaning assembly are short
Phase cleaning device.Such as, for pillar ultrafiltration membrane, with the long-time service of pillar ultrafiltration membrane, what is be retained down in raw water is various
The impurity such as colloid, suspended particulate, microorganism can depend on the surface of pillar ultrafiltration membrane, and some tiny particles can penetrate into fenestra
Middle blocking fenestra, is gradually reduced the separating capacity of pillar ultrafiltration membrane and water yield, when especially source water quality is seriously polluted, more
Easily cause the blocking of ultrafiltration membrane, it is therefore desirable to araeosystyle ultrafiltration membrane is cleaned at regular intervals, such as every 30-60 minutes into
Row cleaning is primary, every time cleaning 30-60 seconds.But after pillar ultrafiltration membrane was run to the long duration, backwash can not will be cut
The impurity stayed in pillar ultrafiltration membrane is fully erased, and the membrane flux of pillar ultrafiltration membrane can be smaller and smaller.At this point, working as pillar ultrafiltration membrane
Water flux ultrafiltration membrane should be cleaned using chemical when decreaseing beyond 30%, to restore the membrane flux of ultrafiltration membrane.
