What is a Reverse Osmosis System and How Does It Work?

Updated: Apr 11, 2020

Have you always wondered what your water is made up of? Below, I will talk about how a reverse osmosis works, what they can remove from your home’s water, why it could be a great fit for your home and some other general information about the systems. Take a look!

Before I dive in, I wanted to give an overview of what a reverse osmosis actually is. A reverse osmosis is a water purification process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. It then separates the filtered water (which is then stored in a storage tank) from the contaminated water (which is flushed down the drain.)

After it passes through the pre-filter and goes through the membrane, it is then stored in the holding tank until water is needed for consumer use. Once the tap is turned on, the water flows through one last filter, the post filter, to ensure that you are getting the best, most filtered water possible.

The pre-filter is designed to filter out sediment, silt, and dirt. It is especially important as the sediment filter protects dirt from getting to the delicate RO membrane that can be damaged by sediment. It is also designed to remove chlorine and other contaminants that affect taste and odor and the overall performance and life of the RO membrane.

The RO membrane is designed to allow water through, but also filter out almost all of the additional contaminants.

The post-filter is designed to “polish” off the water to remove any remaining taste and odor or fine particulates in the storage tank water.

Why choose a R.O. over other filtration systems?

Here are just a few reasons why you should consider a Reverse Osmosis:

1. It improves taste: RO filtration improves taste, odor and appearance of water by removing the contaminants that cause taste and odor problems.

2. It helps with saving money: With an RO system, it completely eliminates the need to buy cases of bottled water every time you go to the store. Reverse Osmosis filtration provides a better quality of water than bottled for a fraction of the cost.

3. Simple Maintenance: RO systems have very few moving or replaceable parts which makes these systems easy to clean and service.

4. Removes Impurities: RO systems remove pollutants from water including nitrates, pesticides, sulfates, fluoride, bacteria, pharmaceuticals, arsenic and much more. An RO systems’ carbon filter will also remove chlorine and chloramines.

Are all Reverse Osmosis systems the same?

There are many different Reverse Osmosis filtration systems on the market. While most look about the same, there can still be major differences between the systems.

Most differ in three basic ways:

1. Number of stages or filters

2. Amount of water that can be filtered or produced each day (this amount is in “gpd” or gallons per day

3. Quality of components
