The RO membrane is the heart of any reverse osmosis system, and that’s why it is essential that a quality RO membrane is well maintained and kept in optimal working condition. The standard reverse osmosis process consists of three stages: pre-filtering, the reverse osmosis process, and post-filtering. Post-filter components are usually of carbon, which will remove any remaining taste and odor. Before changing these filters, make sure to shut off the water supply to your RO system. To successfully ensure efficiency out of your reverse osmosis system, certain routine maintenance steps must be performed.
