TACTICAL WATER PURIFICATION SYSTEM (TWPS)
OPERATOR INSTRUCTIONS
REVERSE OSMOSIS SYSTEM PRESERVATION OPERATION UNDER
USUAL CONDITIONS
RO PRESERVATION FLUSH FOR EXTENDED SHUTDOWN
NOTE
If the daily high temperatures are lower than 40 degrees F and the TWPS is shaded
from direct sun exposure, biological growth is unlikely to occur. Under these
conditions, it would not be necessary to preserve the RO membranes and MF
fibers during an extended shut-down.
This procedure is a part of the extended shutdown procedure (WP 0018). Follow
the extended shutdown procedure and complete the preservation in sequence as
instructed.
1. Make sure the cleaning waste storage tank is set up as follows (see Figure 1):
a. Set up the Waste Tank within 30 feet of the TWPS waste out connection. Face the
female tank connection toward the TWPS skid.
b. If the terrain allows, set the tank at an elevation so that the top of the full tank will be
below the bottom of the RO Feed Tank.
c. Connect an A-16 Adaptor to both connections on the waste tank. Close shut-off valve V-
706 on both of the A-16 adaptors.
d. Be sure that the zipper on the waste tank is zipped closed.
