Reverse Osmosis Membrane Replacement Procedure
(3 min)


For those of us who are kinesthetic and visual learners, this type of video can be very useful as a complement to written instructions. Often we add voiceover or an on-camera instructor who explains each step of the process.

The video illustrates how the reverse osmos (RO) system membrane elements, end caps, interconnectors, stub tubes, and o-rings fit together. For demonstration purposes, the membrane system was assembled outside their pressure vessels on cardbard sheets to demonstrate how all the components fit together inside the pressure vessels. Following this we filmed the removal of the old membrane elements and demonstrated how to properly install them in the RO system pressure vessels. Following this we energized the system took readings with a barcode scanner system to make sure there were no leaking o-rings.

This video was made to assist operators in performing the infrequent procedure of membrane replacement whose details could easily be forgotten. This was an old Osmonics RO system that had been in service for over 20 years. The building it supported was to be demolished in the next few years so my client wanted to make sure it kept making high quality purified water. This required replacing the 4" diameter membrane elements every 18 months or so.
