How to Improve Industrial Water Quality with a Reverse Osmosis System

Installing an industrial reverse osmosis (RO) system provides your company with a good solution for large-scale water purification. Reverse Osmosis is very effective at removing small waterborne contaminants and aqueous salts that may evade other filtration processes. These contaminants, if left in the water, may compromise the quality of the process water.

During reverse osmosis, water is passed at high pressure through a very thin semi permeable membrane, usually made of film polyamide. As the water passes through the membrane, contaminants are forced to the surface and towards the membrane, allowing purified water to pass to the other side, while reject water is pumped away.

Contaminants Removed By Reverse Osmosis

Reverse Osmosis can improve your industrial water quality by stripping out the following contaminants, providing of course that your membranes are efficient and maintained in good order:

Sodium, sulphate, calcium, potassium, nitrate, iron, zinc, mercury, selenium, phosphate, lead, arsenic, magnesium, nickel, fluoride, manganese, cadmium, barium, cyanide

An efficient plant can remove between 85% and 98% of these contaminants, effectively any constituent in water between 0.005 and 0.001 microns in size.

If water needs to be stripped of impurities at the ionic level – i.e. 0.001 microns down to 0.0005 microns and smaller – you will need to use a deionisation or distillation plant.


Effective as reverse osmosis process is, it cannot entirely work on its own. Before water is fed into the reverse osmosis system, it is important to pre-treat it first.

If the water passed in the RO system is not treated, contaminants such as acids, chlorine, calcium and magnesium may corrode the membranes, allowing other contaminants to pass through. Large contaminants such as suspended carbon, viruses and bacteria can also clog the membranes, reducing the efficiency of the system.

Pre-treatment technologies are selected based on the incoming water, typical examples being activated carbon filtration to get rid of chlorine and water softening to remove hardness salts. Many users also employ a variety of filters to remove large contaminants from their feed water.

  • Conventional Particle Filters: Removes human hair, dust, faecal material, red blood cells, pollen etc.
  • Microfiltration: Removes yeasts, tobacco smoke particles, suspended pesticides and small bacteria.
  • Ultrafiltration: Removes suspended carbon and large viruses.
  • Nanofiltration: Removes small viruses, including polio, as well as some of the larger aqueous salts.
