What is Reverse Osmosis?

Reverse Osmosis (RO) is a water purification technology that is used to remove majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. It is a cost-effective method of removing up to 99% of water contaminants, including salts, minerals, particles, bacteria and other substances depend on the quality of the feeding water.

How does Reverse Osmosis work?

Reverse Osmosis Water

In reverse osmosis, a partially permeable membrane acts as a physical barrier to almost all molecules, pressure is created on one side of the water, the membrane allows passage of water molecules which are smaller than its pores(less than 0.0001 micron or 500,000 times smaller than the diameter of a human hair),  result in pure water passes through to the other side of the membrane and blocking large contaminants on the other. Pure water continue to produce under pressure.

“Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis” -Wikipedia

RO Filteration

The above image illustrates how waters flow through the membrane to produce purified water and waste water reject from the filter.

Reverse Osmosis removes:

  • Dissolved organics
  • Dissolved minerals
  • Bacteria
  • Pyrogens

Use of Reverse Osmosis Water

RO water is also known as Type III or Primary grade water, which commonly used in laboratory as glassware washing and instrument bath, autoclave feed, feeding water to ultrapure water system, or used in agricultural as animal watering, plant and sterilizer feeds.
