OP175 System Installation, Operation & Maintenance
10
This section will give you an overview of how
the system works.
• Incoming water is filtered by the prefilters
(1), which remove sediment, chlorine and
organics.
• When the Emergency Bypass Valve (3) is
in the normal SERVICE mode, water flows
through the Processor. When the Bypass
Valve (3) is in System Bypass mode, the
water is diverted directly out to the equipment,
bypassing both the Processor and the
Repressurization Assembly.
• When water in the storage tank is at a low
storage level, the float valve at the tank
(12) opens, lowering the pressure in the
Optimized Water line from the Processor to
the Repressurization Assembly, causing the
Automatic Shutoff Valve (4) in the Processor
to open, allowing feed water to flow through to
the AMS-QT15 membrane (7).
• The membrane feed water pressure is
indicated by the pressure gauge (6).
• The water flows to the inlet of the membrane
(7). The water is split by the membrane into a
pure water stream and a reject water stream.
The reject water flows to the Reject Flow
Control (10) and then on to drain.
• The pure water stream continues through the
Permeate Check Valve (8), and through the
Mineral Addition cartridge (2), then on to the
tank through the Tank Inlet Divert Valve (11)
on top of the Storage Tank (14). Air in the
tank is displaced by the incoming water and
vented out of the Sub-Micron Air Breather
(16).
• When the tank completely fills, the tank
float valve (12) closes, causing pressure
in the Optimized Water Line to rise, which
then causes the Automatic Shutoff Valve
(4) to close, stopping the flow through the
Processor.
• When the “IN” button is actuated on the
Water Quality Monitor (9), it measures the
average TDS of the Optimized Water in
the Pressurized Water Line coming from
the storage tank. When the “OUT” button
is actuated, the Water Quality Monitor (9)
indicates the TDS of the Permeate water
exiting the Membrane (7). If the Bypass Valve
(3) is in System Bypass mode, the Water
Quality Monitor (9) will measure the TDS of
the untreated Feed Water when the “OUT”
button is actuated. The Water Quality Monitor
(9) is battery powered with two AA batteries. It
will automatically shut-off after 30 seconds.
