What Is Reverse Osmosis?
Reverse osmosis is a filtration process that removes dissolved salts, metals, chemicals and impurities by forcing water through a semi-permeable membrane. It can remove particles as small as 0.0001 microns, making it far more effective than standard carbon filtration alone.
How Reverse Osmosis Works
Most reverse osmosis systems use several filtration stages. These typically include sediment and carbon pre-filters to protect the membrane, followed by the reverse osmosis membrane itself, which removes the majority of dissolved contaminants.
System design, water pressure and membrane quality all influence performance, efficiency and waste water levels.
Where Reverse Osmosis Is Used
Reverse osmosis is used across a wide range of domestic and professional environments where water quality directly affects performance, taste or safety.
Common applications include drinking water purification, well water treatment, coffee and beverage preparation, laboratories, healthcare settings, window cleaning and specialist industrial processes.
Benefits & Key Considerations
Reverse osmosis offers exceptional contaminant removal and improved water taste, but it is important to consider factors such as mineral removal, water efficiency, maintenance requirements and installation space.
Understanding both the benefits and limitations ensures reverse osmosis is used where it delivers the greatest value.
