Understanding Reverse Osmosis Systems
How Reverse Osmosis Works
Reverse osmosis (RO) is a water purification process that removes unwanted molecules and larger particles from drinking water. At the heart of the process is a semi-permeable membrane that only allows water molecules to pass through while blocking contaminants. To achieve this, water is pushed under pressure through the membrane, a process that requires pressure greater than the natural osmotic pressure to desalinate and demineralize the water. This means pure water is allowed to pass to one side, while contaminants are flushed away (Apex Water Filters). If you’re curious about the detailed mechanics, our article on how does reverse osmosis system work provides a comprehensive explanation.
