How RO Systems Work and What They Do


It may take more than standard filtration to turn your difficult problem water into something more appealing. Certain types of water need a more advanced solution – that’s where reverse osmosis comes in.

What Is Reverse Osmosis?

Reverse osmosis is a process of water filtration that removes contaminants from water by pressurizing it and forcing it through a semi-permeable membrane. Reverse osmosis technology effectively removes impurities from your water, including sodium, chloride, fluoride, and other contaminants.

In addition to proprietary reverse osmosis membranes, Culligan uses custom technology to address specific problems identified in your water.

Culligan AC-30 Good Water RO System – This triple water filtration system uses reverse osmosis technology and three advanced filtration methods combined into one solution that, together, reduces sediment and impurities, leaving you with fresher drinking water.

Culligan Aqua-Cleer® Advanced RO System – With five stages of targeted water filtration, this solution is one of our most advanced water filtration systems. Smart filtration with reverse osmosis technology addresses your problem water to provide a custom filtration solution with fewer impurities and fresh-tasting water.

Your local Culligan Man is an expert at identifying a custom solution to address your problem water. For more information about reverse osmosis technology, or to determine which water filtration system would work best to treat your water, contact your local Culligan Man today.
