Product Features

Canpure PVDF Outside-in UF membrane is made by Canpure' 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
During the preparation of Canpure 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
Canpure 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
Canpure Outside-in UF membrane has a capillary strength of higher than 10 MPa, standard produced water flux 400Um2 • h • bar at 25°C.

Unique aeration structure
Canpure Outside-in UF membrane adopts unique aeration device inside the module, ensuring more even aeration and better air cleaning effect.

Integrated bundles of fibers
Membrane capillaries in Canpure Outside-in UF membrane module are evenly distributed inside the module by integrating 18 sub-bundles.

Soft Potting
The soft potting technique invented by Canpure 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.

Application

• • Advanced municipal water treatment and drinking water treatment
• • Advanced sewage treatment and reuse
• • Seawater desalination pretreatment
• • Conventional surface water/groundwater treatment

Product Features

Permanently Hydrophilic Membrane (proprietary technology)
The operation flux of most of UF or MF membrane products is much lower than their initial flux resulting from the loss of membrane hydrophilicity by polymer reconfiguration. Canpure SVU UF membrane ensures steady flux by fixing the hydrophilicity permanently, using a cross-link technology.

Lower Molecular Weight Cut Off
Canpure SVU membrane offers a very fine filtration at MWCO of 45,000 Dalton, which is the highest UF filtration grade in water treatment.

Larger Diameter Capillaries
Larger diameters of the capillaries endow better anti-fouling properties to the membranes. Canpure SVU presents only larger diameter UF capillary membranes (ID/OD=1.0/1.5mm, 1.2/1.8mm, 1.5/2.2 mm) for better performances.

Even Arrangement of the Membranes (patented technology)
A large number of membrane capillaries are evenly distributed inside a pressure vessel by a so-called sub-grouping technology so that each membrane capillary works in very similar environments.

Soft Potting (Patented Technology)
The “roots” of the capillaries are the weakest portions in membrane modules, and may break during operation. These portions of membranes in Canpure UF modules are protected by a soft layer of potting material.

Integrated bundles of fibers
Membrane capillaries in Canpure Outside-in UF membrane module are evenly distributed inside the module by integrating 18 sub-bundles.

Soft Potting
The soft potting technique invented by Canpure 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.

Application

Canpure SVU membrane modules can be used to purify well and surface water for drinking water, to filter sewage and waste water for water recycle, and to treat surface or sea water for RO and NF systems.
