e. Potable Water Storage Tank [62] with Product Water
Storage Tank Connection and product water line with
associated piping and fi ttings. This line must be sized
appropriately for the fl ow of Product Water over the
horizontal run and vertical incline of the Product Water
line to the Storage Tank/Cistern. The Product Water
Storage system must be vented to ensure no pressure
build up.
CAUTION: There should be no valves in the
Product Water Line. Damage to the System
occurs if a valve is closed during system
operation.
2.1 SPECIAL CONSIDERATIONS
1. BONDING OF THE HIGH PRESSURE PUMP, FEED PUMP,
and BOOSTER PUMP:
Vessel Installations. The High Pressure Pump, Feed Pump
and Booster Pump may be isolated from the ships bonding
system because of the protective coating applied to the
pumps and their attached motor. As such, there may be
no continuity between the pumps and the ships bonding
system. The path of stray current from the electric motors
may be through the Feedwater Line. This is especially true
if the electric motor grounding wire is insuffi cient. If left
unbonded, the pumps become sacrifi cial and corrosion by
electrolysis takes effect and destroys the pump manifolds,
chambers and impellers. Such destruction renders these
pumps inoperable within just a few short months. The
System Warranty does not cover damage resulting from
electrolysis or improper or inadequate grounding.
Therefore, the pump manifolds and volutes should be
individually and separately bonded to the ships Bonding
System. The ships Bonding System is designed to provide
the same electrical potential to all metal parts which come
in contact with the ocean. This minimizes the potential for
and effects of electrolysis.
CAUTION: Do not confuse the ships
electrical ground with the ships Bonding
System. These are two separate and distinct
circuits, which have two separate and distinct
functions. Using the ships electrical ground
as a means to bond the pumps would
enhance corrosion and rapidly destroy the
pumps.
2. ELECTRICAL GROUNDING OF ALL PUMP MOTORS:
Whether for ship or land applications, the Electric
Motors of all Pumps within the system must be properly
electrically grounded. If left ungrounded, the Pump
becomes the grounding device and is rapidly destroyed by
electrolysis.
The Electric Motors must be individually and separately
c. An electrical power source capable of supplying the
proper current at the proper AC Voltage, Cycles and
Phase to the System.
d. Brine Thru-Hull Fitting for overboard dump (above
water level) for the Brine Discharge Line from the
system. This fi tting must be minimum ¾” {1”} size
with a ¾” {1”} MNPT nipple exposed for coupling with
the supplied System Brine Discharge Connection.
The brine discharge line should be located above
water level to minimize pressure build up on the Brine
Discharge Line. There should be no valves in the Brine
Discharge Line. Damage occurs if the Brine Discharge
is blocked by a closed valve during System operation.
e. Ship’s Potable Water Storage Tank [62] with Product
Water Storage Tank Connection: This fi tting must be
minimum ½” {3/4”} FNPT size for coupling with the
System Product Water Fitting. The Product Water Line
should terminate above water level. The Product Water
Storage Tank must be vented to ensure no pressure
build up during production.
CAUTION: There should be no valves in the
Product Water Line. Damage to the System
occurs if a valve is closed during System
operation.
2. LAND INSTALLATIONS:
a. Feed Source for the R.O. System. The feed source may
be from a deep well, shallow well, directly from the
source, or other means. All necessary components
required for Land Installations including screens,
piping, valves, pumps, & gauges are available from
Sea Recovery. Consult Sea Recovery’s Application
Engineers for assistance. The entire feed line,
including well casings, must be of non-ferrous
materials such as Naval Bronze, PVC, CPVC, or 316L
Stainless Steel. Any ferrous material causes rust
fouling of the R.O. Membrane Element.
The feed source and line must be appropriately sized
to prevent excessive friction losses. The proper feed
fl ow and pressure required at the R.O. System varies
depending upon the actual System confi guration
and installation. Consult Sea Recovery Application
Engineers for assistance.
b. Power cable with the proper gauge rating for this
system’s power consumption.
c. An electrical power source capable of supplying the
proper current at the proper AC Voltage, Cycles and
Phase to the system.
d. Brine Discharge line back to the source or other
suitable discharge location. For well applications do
not discharge the brine back into the feed well. Do not
install any valves in the Brine Discharge Line. A closed
valve in the Brine Discharge line causes damage
