NOTE:
Prior to shipping or storing a system for more than three weeks, the system should
be cleaned with an appropriate cleaner, flushed with water and protected from biological
attack with an appropriate solution for membrane elements. The membrane housing(s)
and plumbing lines of the system must be completely drained. Any water remaining in the
plumbing of a system may freeze, causing serious damage.
Preparation
for
Storage
or Shipment
Preparing the System for Storage
1. Totally immerse the elements in the membrane housing in a solution of 2% M-100 solution, venting the
air outside of the housings. Use the overflow technique: circulate the M-100 solution in such a way that
the remaining air in the system is minimised after the recirculation is completed. After the membrane
housing is filled, the M-100 solution should be allowed to overflow through an opening located higher
than the upper end of the highest housing being filled.
2. Separate the preservation solution from the air outside by closing all valves. Any contact with oxygen
will oxidise the M-100 solution.
3. Check the pH once a week. When the pH becomes 3 or lower, change the preservation solution.
4. Repeat this process at least once a month.
During the shutdown period, the plant must be kept frost-free and the temperature must not exceed 45
°
C.
Preparing unit for shipment:
5. Disconnect the inlet, concentrate, pre-filter and permeate plumbing.
6. Drain all water from the pre-filter cartridge housings by unscrewing the housings, removing the pre-
filter cartridge and draining the water from the housings.
7. Disconnect the tubing from the connectors on the permeate and concentrate inlets and outlets.
8. Fully open the concentrate valve.
9. Drain the flow meters.
10. Allow the system to drain for a minimum of eight hours or until the opened ports stop dripping.
After draining is complete, reconnect all plumbing.
