Product Details

The Canpure curtain type membrane module adopts a full-open design to prevent polluting dead angles 


and is obviously advantageous in large-scale systems with the strengths such as strong adaptability to 


membrane water, high packing density and small floor space.


Product Features

Complex Thermally Induced Phase Separation (c-TIPS) PVDF UF Membrane

/patented technology/


Canpure PVDF membrane is made by Canpure’ s patented c-TIPS technology. It has capillary strength

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 Canpure PVDF 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 membrane has high crystallinity, can tolerate oxidant with higher concentration, and thus

can achieve more profound cleaning effect and longer life.

Double-end Water Production

Permeate water is produced from both the lower and upper ends in Canpure Membrane Modules. This

offers larger flux and more even distribution of fouling load than traditional single-end water production

mode, and also effectively reduces the TMP and prolongs the operation cycle.

Soft Potting /patented technology/

The soft potting technique initiated 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.

Product Introduction

Physical Backwashing

 When the filtering time reaches set value, enter the physical backwashing procedure; single 


membrane tank can be controlled independently, so as to be convenient for backwashing, overhaul and 


maintenance;

 Close the water supply valve, and stop supplying water to membrane tank;

 Continue to implement the water production procedure, till the liquid level of membrane tank reduces to 


the ruled liquid level at the top of submerged hollow fiber microporous membrane module; the detailed 


time shall be determined according to actual system (generally designed as 15-90s), and then stop water 


production procedure;

 Start up backwashing pump, and the backwashing water source refers to water produced by the 


system itself, and the backwashing water flux is 1-15 times as large as water production flux; 


backwashing water penetrates the membrane wall from inner to outer, and then flush pollutants away 


from the membrane surface; while starting up backwashing pump, start up the aeration system, and then 


conduct effective wiping and cleaning to external surface of membrane fiber according to design air 


washing flow; meanwhile, shake hollow membrane fiber, so as to make pollutants fall off;


 Generally, the air-water backwashing duration is 30-90s; if the backwashing water amount exceeds 


liquid level of membrane tank, the backwashing water may flow out of the membrane tank through 


overflow pipeline, and then return to front raw water tank;

 According to detailed water source situation, design to empty the membrane tank after n times of 


backwashing; the membrane tank after being emptied shall be filled with water again in time, and then 


enter the water production procedure after reaching the suitable liquid level; the drained waste water can 


be collected independently, and then return to pre-treatment unit of the system after simple treatment;

Chemical Enhanced Backwashing (CEB)

 The chemical enhanced backwashing cycle of the system will be adjusted according to actual system 


operation situation, and is to be controlled by time;

 The CEB procedure of submerged hollow fiber microporous membrane system adopts sodium 


hypochlorite as frequently used agent, and with regard to individual water sources, it is necessary to add 


hydrochloric acid (or citric acid mixed liquid) agent; the purpose of sodium hypochlorite is to relieve 


organic and biological pollution, and the available chlorine concentration refers to 2-5ppm generally;

 The chemical enhanced backwashing procedure is the same as physical backwashing, and it is only 


necessary to add agent of a certain concentration into backwashing water, so as to strengthen the 


removal effect of pollutants on membrane surface; after CEB is completed, it is suggested that the 


membrane tank should be emptied;

 After above operations are completed, enter the water production procedure automatically;

Application

Application Field

With regard to the projects of different water sources and usages, Canpure submerged hollow fiber

microporous membrane can be used independently or can be used to cooperate with different combined

treatment processes, and its main usages include:

 It can be used for recycle and treatment of up-to-standard sewage and wastewater, which may

effectively reduce SS, turbidity, bacteria and other insoluble substances in sewage;

 It can be used as pre-treatment process of RO/NF, and effectively guarantees that SDI value is smaller

than 3.0;

 It can be used for upgrading and reconstruction project of water treatment plant; it can effectively

utilize landform and original tank body process, and guarantee the removal effect of cryptosporidium 


and giardia;

 It can be used for pre-treatment of sea water desalination, and is applicable to fluctuation of water

quality of water source;

 Chemical enhanced ultrafiltration process, combine enhanced flocculation and oxidation and add

powdered activated carbon, so as to increase stability of system operation and adsorption efficiency of

COD.
