What Is Reverse Osmosis?

Reverse osmosis is an effort that entails removing harmful minerals and ions from your water. The water goes through a semi-permeable reverse osmosis membrane to clean it out.

The RO process is the opposite of osmosis, as the name suggests. Osmosis occurs when compounds in many solutions migrate to form one larger solution. For instance, freshwater can go through many surfaces and eventually collect more sodium ions to produce saltwater.

This makes the water hard for a person to consume. The fresh water in this situation goes through a membrane that causes contaminants to collect and get into the water.

Reverse osmosis works differently, as it forces contaminated water through a membrane to remove the ions and other minerals. The compounds are collected by the membrane to allow the water to stay clean and safe to consume.

The RO works with a few steps:

  1. A pump will take in the contaminated water.
  2. High amounts of pressure are applied to the pump. The pressure will increase on the salt side of the osmosis chamber.
  3. The water is forced into the semi-permeable reverse osmosis membrane.
  4. A reject stream will take in the contaminated content. The stream has to move everything in a different direction.
  5. The permeate water will go in the direction that you want it to move in. This includes a sink tap or other place that you can draw the water out of.

The work by the filter ensures that you’ll clear out various compounds that might compromise the quality of your water. You will remove salt, bacteria, and colloids among other things.

Your RO filter will also take in more water than you might expect. You’ll have to look at the capacity of your filter and how it will fit in your home. In many instances, your filter will work around one tap in your home, particularly in your kitchen. But you can find some whole-home models for your use as well. Check carefully to see how well your filter works.

Some other purification features may come with your filter. These include purification points like ultraviolet filtration. Extra systems are designed to ensure the water in question is protected and will not be difficult to handle.

You’ll still have to look at how well the filter operates if you want to make it work well enough. Don’t forget to look at how much water can be handled at a time.


All the options you have for a RO filter for your home are worth noting. You’ll have to see that whatever you choose to apply works for your home. You’ll appreciate finding a choice for your home that works well with keeping your water under control and healthy for use.
