costs. Sea Recovery utilizes a high effi ciency, marine
quality pump which delivers approximately 40 psi (2.8
bar) into the Media Filter.
9. The booster pump outlet 3-way ball valve controls
the direction of fl ow from the booster pump. Here
the fl ow can be sent into the Media Filter for normal
operation or to the R.O. membrane elements for
cleaning purposes.
10. Flange connection, booster pump outlet to System
at booster pump skid edge allows for connection of
the booster pump skid outlet to the Hydrocylone inlet
fl ange connection.
11. Hdrocyclone fi lter is an option that is recommended
for systems that will be used in areas where the sea
water is heavily laden with suspended solids.
Seperation Range: 15-50 Microns
Capacities: Up to 250 GPM
Sizes: 3 in. (7.62 cm ) and 6 in. (15.24 cm )
12. Flange connection, Hydrocyclone outlet allows for
connection of the Prefi lter inlet skid.
C. PREFILTRATION SUBSYSTEM:
This section of the system receives the raw feed water
from the booster pump and fi lters any suspended solids
down to a minimum 5 micron size (5/1,000,000 meter).
Such controlled pre-fi ltration protects the SRC R.O.
Membrane Element from undue fouling.
The pre-fi ltration subsystem must always be kept clean
in order to allow the proper rate of System feed water
to fl ow through it and into the high pressure pump. A
partially or fully fouled pre-fi ltration subsystem will cause
cavitation damage to the high pressure pump and will also
permanently “foul” the R.O. membrane element.
Always ensure that the pre-fi ltration subsystem is clear, and
monitor it frequently.
1. A 3-way directional control ball valve directs feed
water fl ow into the Media Filter when in the normal
position or allows backwash wastewater to exit the
Media Filter when in the backwash position. In the
“Down” position the valve is set to normal which
allows feed water to enter the top of the Media Filter.
In the “Up” position the valve is set to allow the
backwash wastewater to exit the top of the Media
Filter during the backwash maintenance operation.
2. Media Filter backwash fl ow control valve controls the
velocity (volume) of feed water allowed to backwash
the media bed. The velocity of water must be
controlled. If the backwash water velocity is too great,
the media may be forced out of the fi lter housing
and be fl ushed to discharge. If the backwash water
velocity is too low, the media will not be properly
cleaned.
3. Media Filter backwash fl ow control meter measures
the rate of the backwash water progress through
the Media Filter. The fl ow meter is calibrated in
gallon and liter per minute fl ow. This meter allows
the operator to regulate the Media Filter backwash
fl ow control valve to the required backwash velocity.
Since the meter is clear, the operator will know when
the fi lter bed is clean by observing the condition and
clarity of the backwash water.
4. A low pressure gauges between the booster pump
outlet and Media Filter inlet allows the operator to
monitor the condition of the booster pump and Media
Filter when correlated to pressure gauge.
5. Media Filters are two RFP (Reinforced Fiberglass
Plastic) vessels, which contain a graduated Media
Filter bed (sand and gravel). The media traps
suspended solids, that are larger than 30 microns,
and thus, provides protection and longer life to the
pre-fi lter element. The Media Filter is backwashable,
which minimizes maintenance costs.
6. Media Filter outlet / backwash inlet directional control
3-way ball valve, when used in conjunction with valve
controls the direction of water fl ow out of or into the
Media Filter. In the “DOWN” position, the valve is set
to normal and allows fi ltered feed water to exit the
bottom of the Media Filter. In the “UP” position, the
valve is set to the backwash mode allowing feed
water to reverse fl ow from the bottom of the media
bed.
7. Media Filter drain valve allows draining of the Media
Filter for maintenance.
8. 20 microns cartridge pre-fi lters, installed after
the Media Filter, further fi lter the feed water to 20
microns. These primary cartridge pre-fi lters consist
of RFP housings with a removable lid and specially
treated cartridge fi lter elements. There are over 200
square feed of actual fi lter surface within the two
primary pre-fi lter housings. These unique primary
pre-fi lter elements effi ciently fi lter suspended solids
from the System feed water. It is essential that the
pre-fi lter elements be changed on a regular basis, as
they become fouled.
9. The cartridge pre-fi lter drain valve allows for draining
of the cartridge fi lter canisters during pre-fi lter
element changing and maintenance.
10. The small ball valve located on top of each of
the cartridge pre-fi lter housing allow for air to be
removed from the pre-fi lter housings. Air must be
removed form the housings for safety reasons and
to ensure full utilization of the cartridge pre-fi lter
elements.
