Membrane Replacement and Removal

Replacing membranes in the pressure vessels is an easy process if you have the proper

information and tools at hand. Please refer to the following instructions when removing and replacing

membrane elements:

1. Locate the inlet end of the membrane housing, this is the side that is opposite to the flow

direction.

2. Remove the two M6 x1.0x10 bolts that secure the retainer plates in place with a 5mm Allen head

wrench.

3. After the bolts have been removed, remove both retainer plates by sliding them towards the

center to free them from the grooved ring seat.

4. Remove the end hub from the pressure vessel. This may take a bit of force to do as the end hub

may have come tightly pressed to the walls of the vessel. A pair of pliers may be used to pull on
the hub until it is released. Upon removing set aside.

WARNING

MUST

READ ZERO BEFORE PROCEDING. DISCONNECT
