TACTICAL WATER PURIFICATION SYSTEM (TWPS)
DIRECT SUPPORT MAINTENANCE PROCEDURES
REVERSE OSMOSIS SYSTEM
1) Clamp the flex strut pipe support to the middle of the horizontal pipe.
2) Secure the top right end of the upper MF backwash pipe section using the
sanitary clamp that was removed earlier.
3) Secure the upper MF backwash pipe section to the lower MF backwash pipe
section using the pipe coupling that was removed earlier.
c. Connect the air tubing to the actuator for Valve V-401 in accordance to the tags.
7. Install the MF filtrate pipe section at the right end of the tank as follows (see Figure 3):
a. Position the MF filtrate pipe section as shown in Figure 3.
b. While one person supports the MF filtrate pipe section, secure the pipe section into place
as follows:
1) Loosely clamp the flex strut pipe support to the middle of the MF filtrate pipe.
2) Install Upper Filtrate Outlet Valve and Actuator V-201.
3) Bolt the expansion joint to the bottom of the MF filtrate pipe section.
4) Position the elbow pipe section as shown in Figure 3.
5) Connect the elbow pipe section to the RO tank using the pipe coupling that was
removed earlier.
6) Install Filtrate Flow Control Valve and Actuator V-202.
7) Tighten the flex strut pipe support.
c. Secure the sample/drain hose to MF Filtrate Sample/Drain Valve V-204.
d. Wrap antiseizing tape onto the threads of Pressure Transmitter PT-102 and thread the
transmitter into its fitting on the horizontal pipe section.
e. Connect the air tubing to the actuators for Valve V-201 and V-202 in accordance to the
tags.
8. Make all connections to the bottom and front of the RO feed tank as follows (see Figure 2):
a. Wrap antiseizing tape on the threads of the tee coupling for the HP pump cooling water
return tubes and thread the coupling into the tank fitting.
b. Connect the HP pump cooling water return tubes to the tee.
c. Wrap antiseizing tape on the threads of Level Transmitter LT-201 and thread the
transmitter into the elbow on the tank. Connect the cable to the transmitter.
d. Apply soapy water to the RO feed pump suction pipe and slide half of the hose over the
pipe.
e. Slide the 4 hose clamps over the hose.
f. Apply soapy water to the RO feed tank outlet pipe and slide the other end of the hose
over the outlet pipe.
g. Secure the RO feed pump suction pipe to the inlet flange of the RO feed pump using the
four cap screws, washers, and nuts that were removed earlier.
h. Position and tighten the 4 hose clamps to secure the hose to the suction pipe and the RO
feed tank outlet pipe.
i. Apply soapy water to the cleaning return pipe and the cleaning return inlet on the tank.
Slide the 2 hose clamps and hose over the ends of both.
j. Secure the cleaning return pipe to the cleaning return inlet using the hose clamps.
k. Apply soapy water to the re-circulation pipe and the re-circulation inlet on the RO feed
tank and slide the 3 hose clamps and hose over the ends of both.
l. Secure the re-circulation pipe to the re-circulation inlet adapter using the hose clamps.
m. Wrap antiseizing tape on the threads of RO Feed Tank Auxiliary Drain Valve V-210 and
thread the drain valve into its fitting under the left end of the RO feed tank.
9. (Army only) Install the TWPS skid onto the flat rack. Refer to WP 0071.
