Product Details

Based on the traditional EDI technology, revolutionary innovation is carried out to the internal structure 

of Canpure EDI Module with counter-current full-packing technique adopted, which broadens the water 

supply requirements of EDI, features simple operation and results in low operating costs.

Advantages of EDI technology

A mixed bed ion exchange unit has to be regenerated by using acid and alkali, but an EDI system does not 

need such a process. This is the fundamental advantage of EDI technology over the conventional ion 

exchange technology. However, this advantage can be expressed into other aspects as listed below.

1. EDI process does not consume regeneration chemicals.

2. EDI process does not create waste water and much more environmental.

3. EDI systems do not require shutdown for regeneration.

4. EDI systems are smaller than mix bed ion exchange units.

5. EDI process provides water of consistent quality.

6. Operating expenses are lower than ion exchange units.

Advantages of Canpure super EDI module

Canpure Super EDI has the different advantages from other EDI modules as following:

1. Canpure EDI does not consume salts in operating and need much lower operating expenses.

2. Canpure EDI broadens the feed water limit adequately.

3. Canpure EDI does not need to recycle the concentrate, which makes the system much simpler.

4. Canpure EDI systems require little energy.

Product Introduction

Surfactant cleaning procedure:

1. Measure and record the flow and pressure drop through the electrolyte and concentrate streams.

2. Direct ports (electrodes out, concentrate out and product) back to solution tank for recirculation.

3. Connect the discharge side of a chemical transfer pump, regulated at 30 psi (2 bars), to ports 

(electrolyte feed, concentrate feed and dilute feed).

4. Connect the suction side of the pump to a plastic tank filled with the cleaning solution.

5. Pump the cleaning solution through the EDI module, re-circulate for 5 minutes then turn off the pump 

and allow the cleaner to soak in the module for 30 minutes or longer.

6. Reactivate the pump for a 5-10 minutes recirculation, check pH, if pH drops, then add more NaOH to 


7. Repeated 5-6 until the pH remains stable. Change the solution if too much acid is added.

8. Stop the pump and drain all solution out.

9. Fill the tank with deionized water and pump it through the module to rinse out the cleaner, direct the 

outlet to drain. Continue to add rinse water until the effluent measures no greater than 5 ppm in TDS and 

the pH is within normal operating range. Measure the pressure drop, flow, pH, and TDS, and record.

10. Disconnect the lines from the ports, and connect the ports to their original plumbing.

11. Run the EDI in regeneration mode until an ion material balance is achieved. Run the EDI in standard 

mode until water quality is re-established.

Applications of EDI technology

EDI typically may be used in any applications that require ultrapure water at a resistivity above 

1 Ω•cm. The typical industries that use ultrapure water include:

1. Microelectronic and semiconductor production.

2. Pharmaceutical and biomedical industries.

3. Chemical production.

4. High pressure boiler such as the ones in power plants.
