BM electrolyzer membrane replacement
Thread Content
This year, we plan to replace the membranes in the BM electrolyzers. Could anyone with experience give some advice on the key points to consider? For example, should we disassemble the units and replace the membranes in each unit separately, following the original method of storage, or should we disassemble everything, clean it thoroughly, and then reassemble it all together? Thank you!
If the entire electrolyzer is to have its ion exchange membrane replaced, I think it’s better to disassemble it completely, clean it thoroughly, and then reassemble it all together after everything is ready.
I would like to confirm whether there are experts with experience in film replacement who can provide guidance?
In June 2015, our company carried out system maintenance, involving the replacement of the membranes in all electrolyzers. We did this one electrolyzer at a time: a tower crane was used to lift each unit frame, the old gaskets were removed, and after cleaning them thoroughly, new gaskets were applied before the frame was returned to its original position. This process was repeated for the remaining unit frames.
You can turn to me for film replacement; I have 10 years of experience in this field, and I am particularly skilled in working with Chlorine Engineering, Dinola, and F2 films
1. Completely disassemble. 2. Remove the membrane and gaskets. 3. Rinse the cell tank thoroughly, and inspect the electrode mesh as well as the sealing surfaces of the cell tank. 4. Apply the adhesive gaskets; apply them all. 5. Brush on the release agent. 6. Conduct the pseudo-membrane test and install the membrane.

If the entire electrolyzer is to have its ion exchange membrane replaced, I think it’s better to disassemble it completely, rinse it thoroughly, inspect the electrode grids and sealing surfaces, and then reassemble everything together after everything is ready. It’s more time-saving.
