Reverse Osmosis (RO) is a water treatment technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from water. RO is a highly effective water treatment method that can remove up to 99% of dissolved solids, organic compounds, bacteria, and viruses from water.
RO is commonly used in Packaged Water Treatment Plants (WTP) and Equipment for producing potable water from various sources such as seawater, brackish water, and groundwater. The RO process typically involves the following steps:
Pre-treatment: In this step, the feed water is pre-treated to remove suspended solids, turbidity, and other impurities that can foul the RO membrane. Pre-treatment may involve filtration, chemical treatment, or a combination of both.
RO membrane filtration: The pre-treated water is then passed through an RO membrane, which allows only water molecules to pass through while rejecting dissolved solids, organic compounds, bacteria, and viruses.
Post-treatment: The RO product water is then treated to adjust its pH and mineral content, and to disinfect it to ensure it is safe for consumption.
Packaged WTP and Equipment incorporating RO technology can be used for various applications such as drinking water, industrial process water, and wastewater reuse. RO systems can also be designed for small-scale applications such as in households or for larger applications such as in municipalities and industries. RO technology is an effective and reliable method for producing high-quality potable water from various sources and is widely used in Packaged WTP and Equipment.
