NBC SYSTEM DEPLOYMENT
The NBC (nuclear, biological, chemical) water treatment system is setup as a final product water
treatment step when the raw water source is contaminated with nuclear, biological or chemical warfare
agents. The NBC filter is set up in the product line between the TWPS and the product water storage
tanks. The NBC water treatment system includes the following major components:
NBC filter tank. The filter tank is supplied as standard issue for both the A-TWPS and the MC-
TWPS.
Six bags of ion exchange resin. This filter media is used for removing nuclear and chemical
agents. The filter media is packed inside the filter tank on the A-TWPS and is provided in the
extended capability module for the MC-TWPS.
Four bags of carbon. This filter media is used to remove chemical and biological agents. The
filter media is packed inside the filter tank on the A-TWPS and is provided in the extended
capability module for the MC-TWPS.
NBC hypochlorite injection tube, connector, injector and straps supplied inside the NBC filter tank.
The NBC system can be set up any time before start-up of the TWPS. Typically, the NBC System is set
up when the product water distribution system is set up. Deploy the NBC system as follows:
1. Wear appropriate protective gear as directed.
2. Set up the TWPS as described in WP 0007, Set-Up Operation Under Usual Conditions, or as
described in WP 0009, Cold Weather Set-Up, if applicable.
3. A-TWPS only. Unclamp and remove the band holding the top of the NBC filter. Remove the top
and remove the bags of media. Set the bags between the TWPS and the first distribution tank.
4. Set up the NBC system as follows (see Figure 4):
a. Remove the straps around the NBC tank.
WARNING
Three person lift. Three people are required to safely lift the filter tank. Lift with
your legs, not your back. Three handles are provided for this purpose. Failure to
observe this warning may result in back injury.
b. Lift the NBC tank off of the TWPS skid and carry to a position between the TWPS and the
distribution tanks.
c. Tip the NBC tank and remove the pack-out plate from the bottom of the filter tank.
d. Connect the four 1 -in. x 10-ft. product water hoses to the NBC tank as follows:
1) Connect the end of the second or third product water hose from the TWPS to
the top of the NBC tank.
NOTE
Be sure to check product water TDS and chlorine before connecting the product
hose from the outlet of the NBC tank to the distribution tank.
2) Connect the remaining hoses from the bottom outlet of the NBC tank to the
distribution tank.
e. If the NBC tank is used during cold weather, connect the NBC tank between the last
product water hose and the distribution tank so that the hose heating blanket can be
installed.
