Off-Shore Reverse Osmosis-Image

How Aqua-Chem Reverse Osmosis Works Desalination by Reverse Osmosis (RO) is a process whereby fresh water is extracted from seawater through the use of a semipermeable membrane. An RO watermaker consists of several key components. Prefiltration removes particulate matter from the seawater. Then, a high-pressure pump pressurizes the seawater to approximately 800-1,000 psi. Pressure vessels house the RO membranes where the separation of fresh water from seawater occurs. Approximately 40 percent of the seawater feed is extracted as fresh product. The balance of the water, referred to as "concentrate," is discharged to drain. A real-time conductivity instrument measures the conductivity of the product water. If the maximum conductivity limit is exceeded, product water is automatically diverted to waste. Design Features Sized to fit in minimum space.
