What is Reverse Osmosis?

Reverse Osmosis, commonly referred to as RO, is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable reverse osmosis filter, also called a membrane. To understand the purpose and process of Reverse osmosis you must first understand the naturally occurring process of osmosis. Osmosis is a naturally occurring phenomenon and one of the most important processes in nature. It is a process where a weaker saline solution will tend to migrate to a strong saline solution. Examples of osmosis are when plant roots absorb water from the soil and our kidneys absorb water from our blood.

A solution that is less concentrated will have a natural tendency to migrate to a solution with a higher concentration. A semi-permeable membrane is a membrane that will allow some atoms or molecules to pass but not others. A simple example is a screen door. It allows air molecules to pass through but not pests or anything larger than the holes in the screen door. Reverse osmosis is the process of osmosis in reverse. A reverse osmosis membrane is a semi-permeable membrane that allows the passage of water molecules but not the majority of dissolved salts, bacteria and chemicals. However, you need to 'push' the water through the reverse osmosis membrane by applying pressure that is greater than the naturally occurring osmotic pressure in order to desalinate water in the process, allowing pure water through while holding back a majority of contaminants. Alamo Water Softeners recommends reverse osmosis drinking water systems for those who want the highest quality water for their families. It gives you high quality water now, and protects you and your family from any mistakes the city may make with our water system.
