I am doing some research to design a nanofiltration assisted water treatment plant and wanted to know some information on purchasing membranes.
I am not sure whether or not these membranes come in pressure vessels or if I have to design or procure these separately. Please provide any information on how I could tell if the membrane unit I am buying has a pressure vessel.
Example of what I have been looking at: https://www.lenntech.com/Data-sheets/Dow-Filmtec-NF-2540.pdf In the example it seems to me that a pressure vessel here is not included and one should be bought or procured. If there are any resources you can think of for finding or designing the pressure vessel please let me know.
