Product Details

Canpure Inside-out UF membrane features strong anti-fouling capacity, high capillary strength and high

filtration accuracy. The membrane can effectively reduce the turbidity of raw water, remove suspended

solids, colloids, microorganisms and other substances, and it is characterized by high adaptability to 


varieties of raw water quality, easy operation and maintenance, and can produce water with stable and 


reliable quality.


Product Features

Permanent hydrophilic property

Canpure Inside-out UF membrane is made from modified polysulfone (mPS) material, and treated by cross-

linking hydrophilic composition. The consolidation of the hydrophilic groups endows the permanent 

hydrophilic property of the capillary, more stable product water flux, improved anti-fouling property and 

better cleaning recovery.

MWCO: 45,000 Dalton

Among the similar products in the market, Canpure Inside-out UF membrane has the smallest Molecular 

Weight Cut Off (MWCO) and the highest filtration accuracy, which can effectively ensure the quality of the 

water produced by ultrafiltration.

Unique cross-section structure of the capillary

On the both sides of Canpure Inside-out UF capillary are dense sponge-like structures, and in the middle is 

the finger-like structure, which both ensures the capillary strength and rather high permeability.

High strength and large flux

Canpure Inside-out UF membrane has a capillary strength of 8 Mpa, and a standard produced water flux 

of 450L/m2•h (1 bar at 25℃).

Larger capillary diameter

Canpure Inside-out Capillary has a common capillary ID of 1.2mm and the water entry channel has a 

cross-section area 2.25 times of the common diameter (0.8mm), which significantly improves the anti-

fouling capacity of the membrane modules.

Integrated bundles of fibers / patented technology/

Membrane capillaries in Canpure Inside-out UF membrane module are evenly distributed inside the 

module by integrating 18 sub-bundles.

Soft Potting /patented technology /

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 thus prevents the breaks of the roots of the 

capillaries.
Product Introduction

Clean in place chemical cleaning

Periodically backwashing the membrane can remove most of the fouling matters, but sooner or later, the 


membrane may need chemical cleaning. At designed flow rate, when trans-membrane pressure (TMP) 


is higher than 0.15 MPa, and that cannot be reduced by CEB, a chemical cleaning in necessary. A Clean-


In-Place (CIP) system should be installed with the UF system to facilitate chemical cleaning process.


The cleaning formulation may be selected according to the fouling matters and the operation 


experience. The followings may be considered:

1) A HCl solution at pH=2;

2) A caustic mixture solution of 0.4% NaOH with 2000ppm NaClO at pH≤13;

3) Choose surfactant based on the feed water quality.

Notes: 1) Check the pH value with meter and avoid big error caused by the test paper.

2) Avoid the HCl and NaClO to contact each other during cleaning.

The procedures are as following:

1) Record the operating parameters before CIP chemical cleaning.

2) Open the CIP feed valve and the CIP concentrate recycle valve, circulate the chemical solution for 


30minutes by turning the circulation pump on.

3) Check the pH of the solution, if there is a significant change, add appropriate chemical to resume the 


chemical concentration. Circulate the solution for another 30 minutes.

4) Repeat step 2 until there is no significant pH change. Change the cleaning solution if it gets too dirty 


or too much chemical is added.

5) Stop the circulation pump and let the membrane soaked in the solution for 30 minutes.

6) Close the CIP concentrate recycle valve and open the CIP permeate recycle valve, circulate the 


chemical solution for 30minutes by turning the circulation pump on.

7) Repeat steps 2-4.

8) Drain the solution tank. And run the system by directing permeate to drain until the pH of permeate is 


neutral.

9) Record the operating parameters after chemical cleaning.

Compare the parameters before and after chemical cleaning, if the system is not resumed to its normal 


operation conditions, consider using another cleaning formulation, or call membrane factory for further 


solutions. Make sure the feed pressure of CIP is lower than 0.08Mpa.
