PREFACE
Thank you for your purchase of a Sea Recovery Aqua Whisper
Reverse Osmosis Desalination System. This manual contains
instructions for the installation, operation, maintenance,
and repair of the Sea Recovery Desalination System. This
information is provided to ensure extended life and safe
operation of your Sea Recovery system.
Please read this manual thoroughly before installation
or operation, and keep it for future reference. A better
understanding of the system ensures optimum performance
and longer service life.
Sea Recovery’s Reverse Osmosis Desalination Systems are
designed and engineered to function as a complete working
unit. Generally speaking, the performance of each component
within the System is dependent on the component prior to
it and governs the performance of all components after it.
Proper performance of the system is thus dependent upon
proper operation of every single component within the system.
The intent of this manual is to allow the operator to become
familiar with each component within the Sea Recovery system.
By understanding the function, importance, and normal
operation of each component within each subsystem of the
unit, the operator can readily diagnose minor problems, which
if detected early are usually easily corrected. However, if left
unattended, a problem in one component eventually affects the
rest of the system and leads to further repairs.
The manual is divided into sections that address different
subject matter. Each section should be reviewed before
operating the Reverse Osmosis Desalination system.
The major documented cause of failures and problems are
from the use of third party, non Sea Recovery, parts, from
improper installation, and from improper operation:
The use of third party, non Sea Recovery, consumable, spares,
and assemblies will damage the Sea Recovery system and/
or specific components within the system. Do not use parts,
components from any source other than Sea Recovery. Use of
third party, non Sea Recovery, components will void any and
all warranty of the system and/or void the effected component
within the system.
Sea Recovery maintains inventory for immediate shipment and
our Service Dealers throughout the world maintain stock of Sea
Recovery parts. Always insist on Sea Recovery supplied parts
for your system in order to avoid failures, eliminate problems,
and maintain your Sea Recovery Warranty.
Follow the Installation and Operation Instructions in this manual.
From time to time, Sea Recovery may make programming
changes to the Control Logic.
Other physical production changes may also be made from
time to time and are tracked by Sea Recovery through the
System Serial Number.
Troubleshooting and repair method results can vary
depending on the information that is displayed at the SYSTEM
INFORMATION screen.
When requesting assistance from Sea Recovery
or Sea Recovery’s service dealers, always:
PROVIDE ALL INFORMATION DISPLAYED
AT THE SYSTEM INFORMATION SCREEN.
SERIAL NUMBER helps us to determine the latest
physical version and configuration of your system which
is necessary to ensure that we provide you with the
correct information or parts.
TYPE tells us the production capacity of your system
which gives us a bench mark in diagnosing product
water flow and pressure concerns.
TIME RUNNING assists us in diagnosing abnormalities
that can occur at given operational time intervals such as
required pump maintenance, or R.O. membrane element
condition.
VERSION allows us to determine the specific sequential
operation of the system based on the version of the
programmed control logic.

1.7 GRAPHICS
Graphics used are for reference and illustration
purposes only, and may not represent the actual part or
arrangement of parts in a customized system.
1.8 GLOSSARY
Following terms are helpful in becoming familiar with the
Sea Recovery Reverse Osmosis System.
BOUNDARY LAYER / CONCENTRATION POLARIZATION
When water permeates through the membrane, nearly
all the salt is left behind in the brine channel. In any
dynamic hydraulic system, the fluid adjacent to the wall
of the vessel is moving relatively slow. Even though the
main body of the stream is turbulent, a thin film adjacent
to the wall (membrane) is laminar. This thin film is called
the boundary layer.
At the boundary layer the salts are saturated and can
readily adhere to and pack into the R.O. membrane
element surface if the Feed Water Flow is insufficient.
For this reason it is important to maintain sufficient Feed
Water flow, to prevent Concentration Polarization, through
the R.O. membrane element.
BRINE VELOCITY
The brine flow over the membrane surface is very
important to both product water quality and quantity. At
low flows, concentration polarization occurs, causing the
water quality to decline.
1 INTRODUCTION

Introduction
SPIRAL-WOUND MEMBRANE
The spiral-wound membrane consists of multiple
membrane envelopes each formed by enclosing a
channelized product water carrying material between two
large flat membrane sheets. The membrane envelope
is sealed on three edges with a special adhesive and
attached with the adhesive to a small diameter pipe.
A polypropylene screen is used to form the feed water
channel between the membrane envelopes. A wrap
is applied to the membrane element to maintain the
cylindrical configuration. The center tube is also the
permeate (product water) collecting channel. Several
elements may be connected in series within a single or
multiple pressure vessels).
WATER TEMPERATURE EFFECT
The product water flow through the membrane is
significantly affected by the water temperature. At any
given pressure this flow increases with increasing water
temperature and is reduced at lower temperatures.
The System over comes this factor by self adjusting
the operating pressure to maintain a precise amount of
Product Water Flow.
In addition to inferior product water quality, low brine
flows can increase the precipitation of sparingly soluble
salts which will foul the R.O. membrane element surface
(concentration polarization). If this occurs, the product
water flux (production) will decline.
The Feed Pump integrated design provide a relatively
smooth and continual flow of Feed Water across and
through the R.O. membrane element.
COMPACTION
Some densification of the membrane structure may
take place while operating at elevated pressures, above
1000 PSI. The change is known as compaction and is
accompanied by a reduction in the water permeation rate.
When the R.O. membrane element is subjected to
elevated pressures beyond 1000 PSI the Product Water
Channel becomes squeezed which results in restriction
and in turn product water recovery reduction.
OSMOTIC PRESSURE
The transfer of the water from one side of the membrane
to the other will continue until the head (pressure) is
great enough to prevent any net transfer of the solvent
(water) to the more concentrated (feed water) solution.
At equilibrium, the quantity of water passing in either
direction is equal, and the head pressure is then defined
as the ”Osmotic Pressure” of the solution having that
particular concentration of dissolved solids.
PRESSURE
The operating pressure has a direct affect on product
water quality and quantity. Both factors will increase
as the system pressure increases (higher quantity and
higher quality within design limits).
The system must be operated at the lowest pressure
required to achieve the designed product water flow
rate. This parameter also minimizes compaction, which
proceeds at a faster rate at higher pressures as well as
at higher temperatures.
The System self adjusts its operating pressure to maintain
a precise amount of Product Water Flow. However in
so doing, at low temperatures and or high salinity feed
water conditions the system will operate at higher than
normal pressure in maintaining the specified amount of
product water flow. This is normal, to be expected, and is
due to the design characteristics of the system.
