Sea Water Treatment Ro Plant The process of seawater desalination, aimed at converting seawater into potable water, is widely employed across various regions worldwide. Over the past two decades, advancements in the Reverse Osmosis (RO) process, employing thin-film composite membranes, have significantly reduced the cost of desalination. Notable enhancements in membrane technology, energy recovery systems, pumps, and pressure vessels have collectively contributed to a substantial reduction in the overall cost of desalinated water.

At the core of the desalination process lies Reverse Osmosis technology. In this method, seawater is pressurized and forced against semi-permeable membranes in a continuous flow. Given the high salt content of seawater, the operational pressure for Reverse Osmosis typically ranges between 60-70 bar. As water permeates through the membrane, the majority of dissolved impurities are removed, resulting in the elimination of approximately 99.5% of total salt. The impurities are retained in the flowing water, while the concentrated stream from the membranes is discharged back into the ocean. The design of the entire system must carefully optimize flow rates, membrane surface area, and other conditions to ensure the highest operational efficiency.

Applied Membranes has successfully implemented multiple Reverse Osmosis Systems for seawater desalination. A typical system comprises filtration, UV treatment, chemical injection, and subsequent reverse osmosis membrane stages.
