OMAX® Reverse Osmosis System
Why would your facility consider using a reverse
osmosis system?
Water quality varies depending on location.
In some areas, total dissolved solids can be

What is Reverse
Osmosis?
To understand reverse osmosis, you must
first understand osmosis. During natural
osmosis, water flows from a less concentrated solution through a semipermeable
membrane to a more concentrated saline
solution until concentrations on both sides
of the membrane are equal.
Reverse Osmosis
Reverse osmosis requires external pressure to reverse natural osmotic
flow. As pressure is applied to the
saline solution, water flows from a more
concentrated saline solution through
the semipermeable membrane.
Reverse Osmosis
Membrane
A reverse osmosis membrane has
a thin microporous surface that rejects
impurities, but allows water to pass
through. The membrane rejects 85%-95%
of inorganic solids. Reverse osmosis is a
percent rejection technology. The purity
of the product water depends on the
purity of the inlet water. The purity of
reverse osmosis product water is much
higher than the purity of the feedwater.
Reject Water
A large percentage (50%-75%)
of the feedwater does not pass through
the membrane but flows across the membrane surface, constantly cleaning it and
carrying the inorganic and organic solids
to drain. This water is called “reject.”
sustained at or below 250 ppm, eliminating
pre-treatment measures for effective waterjet
operation. However, in areas where the total
dissolved solids (TDS) rise in excess of 250 ppm,
an OMAX Pressure Reverse Osmosis System can
be just the assurance you need to provide clean,
pure water to your equipment.

When to consider
a water softener?
In some locations you will find the
hardness (calcium and magnesium)
in your water to be high but the TDS
to be below 250. In situations like this
a water softener is recommended. You
will gain many of the same benefits that
a reverse osmosis system would give
you but at a lower cost.

Benefits
• A reverse osmosis system removes
90% to 95% of the total dissolved
solids in your water. Dissolved particles are the primary source of damage
to OMAX waterjet equipment.
• A reverse osmosis system protects your
waterjet equipment so you don’t have
to replace your expendables nearly
as often.
• Virtually hands-free operation.
• Pure water can be used for other
equipment in shop (EDM, etc.).
• More hours of running time between
maintenance.
• Inexpensive filter changes on reverse
osmosis once per month.
• Most cities only charge $2.50 per
1000 gallons making the cost for
water minimal.
About OMAX
OMAX has the industry leading patented
abrasivejet controller with a built-in
expert system. The OMAX Software
makes it easy to machine precision parts
as fast as possible at the lowest cost.
JetMachining is ideal for short-run part
production, just-in-time manufacturing,
tooling, and prototype part development.
It requires no tool changes or complex
fixturing, so you can reduce setup times
by at least 50%.
