Commercial RO (reverse osmosis) system is a type of water filtration system designed for larger-scale applications such as commercial buildings, restaurants, and industrial facilities. The system works in a similar way to a domestic RO system, using a semi-permeable membrane to remove impurities and contaminants from water. However, a commercial RO system is typically larger and more complex, with multiple stages of filtration and a higher capacity for water treatment. The system may include pre-filters to remove sediment and other larger particles, a carbon filter to remove chlorine and other organic compounds, and a reverse osmosis membrane to remove dissolved minerals and contaminants. The purified water is typically stored in a large tank and distributed through a network of pipes or dispensers. Some commercial RO systems may also include additional features such as a UV sterilizer to kill bacteria and viruses, a deionization stage to remove minerals and dissolved solids, and a water softener to prevent scale buildup. It is important to choose a commercial RO system that is appropriate for the specific application and to follow the manufacturer's instructions for proper installation, use, and maintenance to ensure optimal performance and water quality.
