In recent years, RO water filtration has become more popular because it cleans the water to a very high standard. But, many homeowners don’t fully understand this process and there are a few myths about the safety of RO drinking water. In this article, we will take a closer look at RO water to help you make an informed decision.

What is Osmosis?

This is the process of moving a solvent through a semi-permeable membrane to change the composition to a lower concentration. Essentially, this will equalize or create an equilibrium on both opposite sides of the membrane. When we think of osmosis and how it relates to water, it’s an efficient way to separate the pure water molecules from the contaminants,

How Does Reverse Osmosis Work?

Water is a solvent, it can dissolve many materials it passes through and they are added to its makeup. When you use an RO filtration system, the incoming water is placed under pressure and forced through the semi-permeable membrane. The contaminants are left behind on the surface and the water molecules pass through. This produces water that is cleaned to a very high standard, but the process can take a while so the cleaned water is stored in a tank for easy access.

This process was invented by Jean Antoine Nollet, a French physicist working in the 18th Century. Over the years, the technology was refined and it has been used to turn seawater into potable water by the US Navy. In recent years, the technology has become more practical for home use and many homeowners are installing RO systems. This is a mechanical process, no chemicals are added to the water and RO water is about as close to pure water as you can get without impractical distillation methods.

Is RO Water Safe to Consume?

Yes, RO water is free from a wide variety of contaminants, including aluminum, sulfates, pesticides, fluoride, heavy metals, and even nuclear waste materials. The contaminants are left behind on the surface of the semi-permeable membrane and are periodically flushed away into the drain. When you drink or cook with RO water, you will notice a marked change in the taste of your drinks and food. The lack of contaminants will mean that you may be tasting the true taste of your favorite foods and beverages for the first time. Some people find RO water to have a bland taste, but most modern systems have a granular activated carbon (GAC) post filter to add some character and polish.

RO water treatment systems use a number of filters and the semi-permeable membrane to clean the water. These need to be changed and the full details for your system are included in your owner’s manual. As a general rule of thumb, you may need to change them every six months or so.

If you want cleaner and fresher drinking water for your home, contact your local water treatment specialist and ask them about an RO filtration system installation.
