2.4 COMPONENT DESCRIPTIONS
Components are installed in several modular skids forming
a complete System. Refer to P&ID foldout in
Section 10 .
A. FEED SOURCE EXTERNAL TO THE SYSTEM:
This section of the System collects, fi lters and delivers the
system feed water into the system. The feed source may
be collected directly from the source or through a well,
other natural fi lter bed or a ship’s sea chest.
A beach well lateral or feed source screen pickup is the
initial point at which the feed water enters the System line.
A lateral will be used if the inlet will be from a beach well
or other natural Media Filter. If the feed is taken directly
from the source then the suction line can be fi tted with a
suction screen.
1. Feed source which will be direct from the ocean,
river, well or other natural body of water, which is to
be treated with the Sea Recovery Reverse Osmosis
Desalination System.
2. The feed line check valve (or non return valve) is used
in the suction line to ensure that the feed line remains
full of feed water during shutdown periods.
3. The coarse strainer is a basket fi lter body with a
cleanable fi ne mesh fi lter screen. Its design allows
for quick bowl removal. The coarse strainer fi lters
out large particulate matter. The fi ne element traps
suspended particles that would otherwise enter and
damage the feed water and/or booster pump. The
result is lowered maintenance costs. The coarse
strainer is designed for vacuum use and will not
withstand pressure. The coarse strainer is not
necessary if the feed source is from a well or other
natural fi lter bed.
B. SUCTION LINE SUBSYSTEM:
This section of the System fi lters suspended solids
from the feedwater of the system before it reaches the
High Pressure Pump and R.O. Membrane Elements. The
Feedwater may be collected directly from the source,
from a well, or through a ship’s Sea Chest / Inlet Thru Hull
Fitting. The raw feed water is fi ltered to remove suspended
solids larger than 5 Micron size (5/1,000,000 of a meter).
The pre-fi ltration protects the R.O. Membrane Elements
from fouling.
Always ensure that the Pre-Filtration Subsystem is clear
and monitor it frequently.
1. Well water pump isolation valves allow for complete
isolation and shut-off of the system feed water
pump. These valves allow the pump to be removed
for maintenance while maintaining the prime in the
system feed water line.
2. The feed water pump supplies a positive pressure to
the inlet of the System booster pump. A feed water
pump may be required to deliver a positive pressure
into the booster pump. Consult Sea Recovery’s
application engineering department for details if the
supplied booster pump is unable to suck and deliver
the proper fl ow and pressure into the System.
3. System feed water pump priming / well purging valve
is used to prime the feed water pump as well as
purge the beach well. Any new well must be purged
for several days in order to clear it from fi nes and
establish consistent fl ow.
4. System feed water pump isolation valves allow for
complete isolation and shut-off of the System feed
water pump. These valves allow the pump to be
removed for maintenance while maintaining the
prime in the system feed water line.
5. The booster pump skid inlet fl ange connection allows
for connection of the feed line into the booster pump.
6. The 3-way ball valve at the booster pump inlet
controls the feed source direction, which can either
be normal operating feed water or storage chemical,
cleaning chemicals or fresh water for rinsing.
7. Booster pump inlet pressure gauge (compound
gauge) -30 to 60 psi (-2.1 to 4 bar) monitors feed
water pressure or suction into the booster pump from
the feed water source or feed water pump.
8. The booster pump supplies a positive pressure to the
pre-fi ltration section and, in turn, to the high pressure
pump. Positive pressure will provide longer life to the
Media Filters and pre-fi lters, provide longer life to
the high pressure pump and also decrease required
maintenance and decrease associated maintenance
