Element Removal
Elements may have to be removed from the pressure vessels. Some possible
reasons are:
x
Inspection
x
Long term storage
x
Shipment
x
Replacement
The procedure to remove elements is as follows:
Before removing connection from the feed, brine and permeate
piping ports on the pressure vessel, the remaining water in
pressure vessel should be drained out to release the pressure
inside.
1) Remove connection fittings from the feed, brine and permeate piping ports
on the pressure vessel.
For side port and multiport pressure vessel configurations,
removal of the permeate piping connections from the end plates is
all that is required.
2) Remove the pressure vessel end plates from both the feed and
concentrate ends of the pressure vessel.
3) Push the element stack into the vessel from the feed end of the pressure
vessel. Push the element stack forward so the brine end element sticks out
of the pressure vessel far enough for the operator to be able to grip the
element and pull the reminder of the element out of the pressure vessel.
4) When removing the downstream element from the brine end of the
pressure vessel, pull the element straight out. Do not apply any load up,
down, or side to side on the interconnector that connects the element
being removed to the upstream element(s) still remaining in the pressure
vessel. Excessive load can damage the interconnector, product tube, brine
seal, or interconnector O-rings.
5) Repeat procedures 3) and 4) to remove the remaining element(s) in the
pressure vessel. A section of PVC pipe can be used to push the elements
forward towards the brine end of the vessel for removal.
