The History of Reverse Osmosis Filtration

The process of osmosis has existed in nature for millions of years, though it wasn’t discovered until 1748 by a French physicist and clergyman named Jean-Antoine Nollet. He was able to prove that a solvent was able to selectively pass through a semi-permeable membrane and the solvent would enter through the cell membrane until equilibrium is attained on both sides of the membrane. It wasn’t until the 1940’s when American researchers found a renewed interest in osmosis while trying to discover a method of desalinating sea water.

In 1959, two American researchers produced a functional synthetic RO membrane made from cellulose acetate polymer. They used a body of high solute water and used a pump to force pressure through the membrane, which only allowed water to pass through, and rejected TDS and salt. Because this process works in reverse of the natural osmotic process, it quickly became known as reverse osmosis. Over the last decade, reverse osmosis has become a major part of analyzing, purification, processing, and manufacturing of water.

The Process of Reverse Osmosis

Osmosis is a process that occurs naturally in plants, our bodies, and other forms of nature. Osmosis is when two liquids of different concentrations, which are separated by a semi-permeable membrane, move from low to high solute to reach equilibrium.

Reverse osmosis is when the liquids move from high to low solute with the use of a pump creating pressure in the opposite direction. The pressure created in the reverse osmosis system must be greater than the osmotic pressure in order for the process to work. This is why higher pressure is required in desalination systems and lower pressure is required in smaller tap water systems.

Reverse osmosis is the most economical technology to purify water to extremely high quality standards.

What Makes Up a Complete Reverse Osmosis System?

Typically, a reverse osmosis system is only a part of a water purification process. There are several other components and types of systems that can be added on before and after the industrial RO system to attain better water quality and to extend the life and effectiveness of the reverse osmosis system.
Complete Reverse Osmosis System
  • Pre-Treatment – This includes many options that can be placed before the reverse osmosis system, such as filter cartridges, water softener systems, and antiscalant systems.
  • Storage and Distribution – It is necessary to have a tank to hold the RO water. Bladder and atmospheric tanks are the two types used in reverse osmosis systems. Only atmospheric tanks can be used in larger industrial reverse osmosis systems, while the bladder tanks are used for smaller systems under 80 GPD. When using a bladder tank, there is usually no need for a pump, but when using an atmospheric tank a booster pump is needed to re-pressurize the water and distribute it.
  • Post-Treatment – This includes many options that can be placed after the reverse osmosis system, such as ultraviolet sterilizers (UV) or ozone generators to kill bacteria, a pH adjustment filter to raise the pH or add some hardness back to the water, and/or deionization to completely demineralize the water.
  • Instrumentation – monitoring the quality of the permeate water is often desired, so a number of instruments are available, such as pressure gauges and flow meters.

Typical Reverse Osmosis System Process:

  • Raw Water Storage Tank
  • Feed Water Pump
  • Pre-Filtration
  • Media Fitler System
  • Water Softener System
  • Antiscalant System
  • Reverse Osmosis System (RO Membrane)
  • Product Water Atmospheric Storage Tank
  • Post-Filtration
  • Re-pressurization Pump
  • Ultraviolet Disinfection
  • Deionization Cartridges

Designing an Industrial Reverse Osmosis System

  • It is very important to consult one of our AXEON engineers to find the best solution for pre-treatment possible in order to reach your water quality needs and maintain your industrial RO system much more easily. The water needs to be as soft as possible; otherwise an antiscalant must be fed before the system to prevent membrane scaling. In most cases, an antiscalant injection system is the preferred and most cost effective method of pre-treatment.
  • An industrial RO system operates at its best when it is fed into an atmospheric tank. With no back-pressure from the bladder of a pressurized storage tank, an industrial RO system will deliver water that is extremely low in TDS. In fact, it is not unusual for the TDS to be almost zero when the system is fed into a atmospheric tank. In food service applications or other applications where extremely low TDS is not critical, a bladder tank can be used, but if a manufacturing process calls for extremely low TDS water, then the atmospheric tank is by far the best option.
  • The permeate water must be re-pressurized out of the atmospheric tank(s) so the proper size pump must be used for the industrial RO system.

Factors in Designing an Industrial Reverse Osmosis System

Here are just a few factors to consider before deciding on a system:
  • Hardness
  • TDS
  • Chlorine Level
  • Iron Level
  • Manganese Level
  • Silica
  • Barium or Strontium + Sulfate (SO4)
  • Turbidity
