Reverse Osmosis is a method that uses micro-porous spiral-wound membranes to separate the dissoluble solids, organic matter, colloids and bacteria from the water. With certain pressure, the raw water is carried to the RO membrane, passes through its small aperture, and pure water is produced. The rejected matter is drained with the concentrate water. RO membranes can remove over 98% of dissoluble solids, over 99% of organic matter and colloids and almost 100% of bacteria.

A RO system is one of the most advanced water purification systems available. Low cost running expense, easy operation and reliability make it an excellent choice for producing pure water.
