Forward Osmosis (FO)

Forward Osmosis (FO) is an innovative low-energy membrane technology that uses the natural pressure of osmosis to separate water from dissolved solids. Instead of relying on high hydraulic pressure like Reverse Osmosis (RO), FO uses differences in osmotic pressure to draw water across a semi-permeable membrane, making it an efficient and sustainable solution for brine concentration and resource recovery. Forward Osmosis is particularly effective for treating challenging wastewater streams with fouling risk and high levels of organic contamination.

At FTS H2O, our COAR™ family of membrane elements and ConcentratOAR™ integrated solution harness the power of FO technology to address the unique needs of various industries, offering innovative solutions that drive efficiency and quality in resource recovery processes.

FTS H2O, an Aquatech Company, offers Forward Osmosis (FO) solutions through its COAR™ family of membrane elements and the ConcentratOAR™ integrated system. Together, these technologies leverage the benefits of FO to concentrate challenging streams, increase resource recovery for beneficial reuse, and reduce fouling and energy consumption. COAR™ FO membranes provide the core separation technology, while ConcentratOAR™ integrates FO into a complete end-to-end treatment solution for industrial wastewater concentration, resource recovery, and water reuse applications.
