The water seepage of the EDI module in the ultra pure water equipment has undergone preparatory treatment and the reverse osmosis system software has greatly reduced the opportunity for internal blockage of the membrane block. However, with the extension of machine operation time, the internal water path of the EDI membrane block may cause blockage. When encountering the above situation, it is necessary to clean the EDI module in the ultrapure water equipment to restore it to its original technical characteristics.

How to clean the EDI module in ultrapure water equipment

1. Online cleaning: Online cleaning refers to the overall cleaning of the reverse osmosis system software. Membrane electronic devices do not require the removal of pressure vessels, and are generally designed and used in very large systems. This cleaning method is convenient and fast to use, with a faster speed. The disadvantage is that the cleaning is not thorough and the expected effect is not rational.

2. Offline promotion cleaning: Offline promotion cleaning refers to the removal of EDI modules from reverse osmosis pressure vessels in ultra pure water equipment and placing them in specialized cleaning machinery for cleaning. This cleaning method is convenient, convenient, and fast to use, with thorough cleaning and good expected results.

Common problems with EDI module cleaning in ultra pure water equipment

1. The machine equipment pipelines that must be cleaned must be thoroughly protected from the connecting pipelines of other machine equipment.

2. The switch power supply of the machine equipment that must be cleaned must be completely disconnected and have a safety warning sign that "it has been actually operated and cannot be turned on".

3. The pressure during the entire cleaning process should not exceed 0.15 MPa.

4. Prohibit the use of xylene or other solvents.

5. Maintenance safety factor sign.
