To understand reverse osmosis, you must first understand osmosis. During natural osmosis, water flows from a less concentrated solution through a semi-permeable 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 semi-permeable 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."

Why would your facility consider using a reverse osmosis system?
As you know, water quality varies depending on location. In some areas, total dissolved solids can be sustained at or below 100 ppm, eliminating pretreatment measures for effective waterjet operation.
However, in areas where the total dissolved solids (TDS) rise in excess of 100 ppm, an OMAX Low Pressure Reverse Osmosis System can be just the assurance you need to provide clean, pure water to your equipment.
A reverse osmosis system removes 90% to 95% of the total dissolved solids in your water. And since these dissolved particles are the primary source of damage to the sensitive orifice, mixing tube and inner workings of OMAX waterjet equipment, their removal assures a longer component life and a greater measure of quality performance.
A reverse osmosis system can save you money by protecting your waterjet equipment thus not having to replace your expendables nearly as often.
Benefits
- 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 (3,800 liters) making
the cost for water minimal
In some locations you will find the hardness (calcium and magnesium) in your water to be high but the TDS to be below 100. 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.
