What Is Reverse Osmosis?

Many of our readers have asked questions about reverse osmosis drinking water filtration systems and want to know more about them. Hence the purpose and reason for this deviation from the normal subject matter in this Water Testing Blog entry.

Reverse osmosis involves the passage of potable water through a semi-permeable membrane. In a normal osmotic reaction, water containing a dissolved substance in low concentration will flow through a membrane to the side containing a higher concentration of the dissolved substance. If pressure is applied to the side having the higher concentration of solution, the flow of water can be stopped or even reversed. When the flow is reversed, this is called ‘reverse osmosis.’ In this case, it is the water that has less dissolved substance that is desirable; this is the purified water.”( source )”
