C. INTRODUCTION
The Obstacle:
Osmosis is the naturally occurring
diffusion of two miscible (mixable)
solutions through a semipermeable
membrane in such a manner as to
equalize their concentration by
allowing a lessor concentration,
potable water, to naturally diffuse
through a semipermeable
membrane into a higher
concentration, sea or brackish
water.

Manifold
Sea water or brackish water is a high
concentration solution. Potable
water is a low concentration
solution.
Therefore, sea water or brackish
water cannot naturally diffuse
through a semipermeable
membrane to provide potable, or
drinking water.
The HRO Solution:
A manmade process, Reverse
Osmosis, overcomes this natural
phenomenon. By forcing sea or
brackish water (under high pressure)
through a semipermeable
membrane, potable water can be
realized. Reverse Osmosis
Desalination Systems by
HROSystems make possible the once
impossible, potable water from
undrinkable water sources.

Low Pressure: Feed Water (Salt
Water or Brackish Water) enters the
system through an Inlet Valve and is
then filtered by a raw water Sea
Strainer. The pressure of the Feed
water is increased by the Booster
Pump and filtered several more times
through standard and optional
prefiltration units including Media
Filter, Plankton Filter, Prefilter and
Oil Water Separator.
High Pressure: The Stainless Steel
High Pressure Pump then increases
the filtered feed water to a high
pressure level and forces it into the
Reinforced Fiberglass Membrane
Vessel Assembly. The Back Pressure
Regulator controls and automatically
maintains the necessary high
pressure level in the membrane.
Concentrated brine enters the Brine
Water Flow Meter which allows
observation of the condition of the
High Pressure Pump. The Brine
Water is then discharged through the
Brine Discharge Connector and
diverted back to the feed source.
Product Water: The product
water flows out of the R.O.
Membrane and passes into a Salinity
Probe which adjusts automatically
for temperature changes and

electronically, the salt content of
the product water. Next, the
Product Flow Meter registers the
amount of potable water being
produced. The product water then
proceeds into the 3-Way Solenoid
Diversion Valve. Here, potable
water is diverted to the Charcoal
Filter where gasses or odors present
are absorbed and removed from the
product water. The final filtration
process occurs in the Ultraviolet
Sterilizer where 99.9% of all
microorganisms, including viruses
and bacteria, are destroyed.
Rinsing and Cleaning: The
3-way valves are provided for
System Rinsing and Cleaning. The
Automatic Fresh Water Flush
System maintains fresh water
within the System during shut
down periods.
Electronics: All electrical
connections terminate at the
Salinity Controller. Highly
advanced, the Salinity Controller
features computer controlled
reliable solid state electronics with
advanced proprietary logic features
found in no other desalination
system. Various Remote Control
units are available for remote
operation of the System.
