DESCRIPTION AND THEORY OF OPERATION
THEORY OF OPERATION
OPERATING CONTROLS
The Operating Controls include the Operator Control Panel (OCP), the Feed Flow (FF) Control Panel, the
Programmable Logic Controller (PLC) (see Figure 27). It also includes several indicators and controls off
of the OCP that require occasional adjustment and monitoring for manual operation. The OCP provides
all of the push buttons, switches, alarm lights and displays needed for operator control and monitoring of
the system. The Feed Flow Control Panel controls the operation of Flow Control Valve V-202, which
controls the flow of filtrate from the MF system to the RO feed tank. The PLC provides automated control
after operator startup and in response to operator switch selections. Indicators and controls throughout
the TWPS MF and RO systems provide the operator with local indications of system conditions and
manual controls for certain operating functions of the TWPS.

POWER DISTRIBUTION SYSTEM
The Power Distribution System distributes electrical power to components within the TWPS and to the
pumps deployed off of the skid during operation. The power distribution system includes the following
major components:
60 kW TQG (Tactical Quiet Generator) or (for the MC-TWPS) alternative 416 Volt AC, 3-phase
power source. The TQG is provided with the A-TWPS. The MC-TWPS comes without the TQG.
Power distribution panel. The power distribution panel is located below the operator control
panel and behind the lower panel door (see Figure 28). It contains the circuit breakers and
motor starters needed to provide power to all of the electrical devices included in the TWPS.
