Product Features
“Complex Thermally Induced Phase Separation” (c-TIPS) PVDF UF membrane
/ patented technology /
PVDF Outside-in UF membrane is made by LEFILTER' s patented c-TIPS technology. It has capillary
strength about 3 times higher than PVDF membrane prepared by NIPS Method and much better filtration
grade than PVDF membrane prepared by conventional TIPS Method.
Permanent hydrophilic property / patented technology /
During the preparation of Outside-in UF membrane, hydrophilic substances are added and special
cross-linking technique is applied, endowing the permanent hydrophilic property of the capillary, more
stable product water flux, improved anti-fouling property and better cleaning recovery.
High anti-oxidation performance
PVDF Outside-in UF membrane features high crystallinity, can tolerate oxidant with higher
concentration, and thus can achieve more profound cleaning effect and longer life.
High strength and large flux
Outside-in UF membrane has a capillary strength of higher than 10 MPa,standard produced water
flux 400L/m²•h•bar at 25℃.
Unique aeration structure
Outside-in UF membrane adopts unique aeration device inside the module, ensuring more even
aeration and better air cleaning effect.
Integrated bundles of fibers / patented technology /
Membrane capillaries in Outside-in UF membrane module are evenly distributed inside the
module by integrating 18 sub-bundles.
Soft Potting / patented technology /
The soft potting technique invented by LEFILTER realizes the flexible connection between the “root” of the
capillaries and the soft layer of the potting material, and prevents the break of the root of the capillaries.
