1.what is  Reverse osmosis (RO)? 

 2.How does a Reverse Osmosis Membrane work?

Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. These impurities and contaminates are flushed down the drain.

3.Advantages of Reverse Osmosis  Membrane 

• Improves taste, odor and appearance.
• Highly effective purification process. Will remove the pollutants listed below and more!
• Consumes no energy
• Very convenient
• Flushes away pollutants, does not collect them
• Easy to keep clean
• Low production cost - gives you water of a guaranteed quality for pennies per gallon
