Product Profile

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.

Features of CPI series inside-out UF module

Canpure CPI membrane modules are created with advanced membrane formation technologies and 

unique module structures that provide superior filtration efficiency and durability. The features are as 


1.Permanently hydro-phyllicity (for steady flux)

The Hydro-phyllicity for all kinds of UF membrane is very important for the anti-fouling and stable flux 

properties. The CPI series membrane capillaries made with modified polysulfone, are intensively 

chemically and thermally treated after the formation of the membrane yielding permanently hydro-

phyllicity properties. Resulted from this permanent hydro-phyllicity, Saveyor UF membranes offer higher 

anti-fouling properties against organic pollutants, higher and stable operating flux.

2.Better permeate distribution for steady flux(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.

3.Larger capillary diameters (for steady flux)

It is widely accepted that the larger inner diameter of UF membrane capillaries, the better anti-fouling 

properties for the UF module. Canpure UF membrane capillaries are made of relatively large inner 

diameters that are 1.0mm, 1.2mm, and 1.5mm. Users can choose the property UF modules according to 

the quality of raw water.

4.Soft potting (patented technology)

The “roots” of the capillaries (hollow fibers) are the weakest portions in membrane modules, and may 

be broken during operation. These portions of membranes in Canpure UF modules are protected by a 

layer of soft potting material.

5.Lower molecular weight cut off

Canpure CPI membrane offers very fine filtration at a MWCO at 45,000 Dalton, which is the very high end 

of UF filtration grade in water treatment.

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 


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.
