TACTICAL WATER PURIFICATION SYSTEM (TWPS)

DESCRIPTION AND THEORY OF OPERATION
EQUIPMENT DESCRIPTION AND DATA
MF System: MF Modules to Waste Outlet (see Figure 11 and Figure 12)
Shell Backwash Upper Outlet Valve V-401. Opens to discharge the backwash flow from the
upper shell of the MF Assembly.
Shell Backwash Lower Outlet Valve V-402. Opens for the air pressure pulse during backwash
and when draining the MF.
Rupture Disk RD-401. Rated for 75 psig. The backwash operation creates a sudden and very
high velocity surge in the waste out piping and hose. In the event that the waste out hoses are
blocked in any manner, the rupture disk will rupture when pressure exceeds 75 psig to release
the pressure and protect the TWPS equipment.
MF Shell Drain Valve V-403. Used to drain the shell/waste outlet channels of the MF Assembly.

Adaptor A-09. Connects the 4-in. diameter waste out suction hose to a 6-in. diameter flexible
waste out discharge hose.
One 6-in., 50-ft. long discharge hose. Discharges the backwash flow and RO reject away from
the TWPS.
