Reverse osmosis. Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.
Membrane and Module Autopsy. The physical dissection of a reverse osmosis (RO) element or microfiltration/ultrafiltration (MF/UF) module and the resulting analysis of its foulants can be one of the most definitive methods of troubleshooting a system.Identifying the cause of performance loss is only part of this valuable service.he physical dissection of a reverse osmosis (RO) element or microfiltration/ultrafiltration (MF/UF) module and the resulting analysis of its foulants can be one of the most definitive methods of troubleshooting a system.
