Product Profile

Canpure Outside-in Membrane Module features large membrane area per module, strong anti-fouling 


capacity,high chemical resistance and large flux under low pressure.The membrane can effectively 


reduce the turbidity of the raw water, remove suspended solids, colloids, microorganisms and other 


substances, and it is characterized by high adaptability to varieties of raw water, easy operation and 


maintenance, as well as stable and reliable quality of produced water.


Features of CPO Series outside-in UF module

The performances of the membranes made by the c-TIPS method are superior to that made by the NIPS 


or the classical TIPS method using the same materials. It can greatly solve the problem of the 


membrane’s easy broken. The CPO membrane modules offer the following features:

1. Longevity 


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


unique module structures that provide superior filtration efficiency and durability.

2.Robust membrane (patented technology)

Canpure CPO membrane is made by the c-TIPS technology which endows the membrane with high 


crystallinity. As result, the membrane is good at chemical resistance, mechanical strength and longer 


life time.

3.Permanently hydrophilic membrane (proprietary technology)

The operation flux of most UF or MF membrane products is much lower than their initial flux resulting 


from the loss of membrane hydrophilicity by polymer reconfiguration. Canpure PVDF UF membrane 


remains permanent hydrophilic and thus, offers steady flux.

4.Oxidation-inert membrane

Capure CPO Series membrane modules can be cleaned thoroughly by strong oxidant because of the 


chemical inertness of PVDF polymer.

5.Air lift recirculation (patented technology)

An air diffuser is installed inside this series of Canpure membrane modules so that air may be evenly 


distributed around membrane capillaries. Water is “carried” upward by this air flow and “drained” 


downward through a central pipe and such as to create a water recirculation current. This Air Lift 


Recirculation (ALR) current may greatly reduce membrane fouling.

6.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.


7.Low operation pressure

Typically, Canpure CPO membrane is designed to be run at pressure as low as  0.02MPa (3.0 psi) to 


produce enough water.


8.Better permeate distribution(for steady flux)

The “sub-unit” arrangement of the capillary membrane in a Canpure UF module offers a better 


distribution of water flow in the module.

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≥1;

2) A caustic mixture solution of 0.04% NaOH with 200ppm NaClO at pH≤12;

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.
