Forward Osmosis 500 GPD

The AMPAC USA Forward Osmosis 500 GPD system takes a fundamentally different approach to water purification than standard reverse osmosis. Instead of forcing water through a membrane with hydraulic pressure, it draws water across a specialized membrane into a draw solution with higher osmotic potential, relying on natural osmotic pressure rather than mechanical force. This gentler separation process achieves high rejection rates against salts, heavy metals, organic compounds, and microbial impurities, while minimizing reverse back diffusion so both the treated water and the draw solution retain their integrity — a key advantage for applications where product purity is critical.

• Uses osmotic pressure instead of hydraulic pressure for gentler, low-fouling separation
• High rejection of salts, heavy metals, organic compounds, and microbial impurities
• Minimizes reverse back diffusion to protect treated water and draw solution integrity
• 500 GPD capacity suited to small-to-medium scale treatment needs
• Lower energy consumption compared to high-pressure membrane processes

Rated at 500 gallons per day, the FO500 Forward Osmosis Plant is sized for small to medium-scale water treatment requirements that call for a consistent supply of purified water without the footprint of an industrial-scale system. Because the process rejects contaminants while simultaneously retaining valuable compounds, it opens the door to resource recovery alongside purification — a dual capability that makes the FO500 useful for industries that need to both clean water and recover beneficial elements from their process streams.

Typical applications span industrial wastewater treatment, concentration of industrial process streams, and recovery of valuable solutes from dilute solutions. In food and beverage production it can concentrate fruit juices and dairy products or dewater process waters, while in pharmaceutical manufacturing its gentle operation suits concentrating heat-sensitive compounds or purifying water for critical applications. It is also well suited to specialized municipal uses, including difficult-to-treat wastewater and emergency water purification in remote locations with limited power, and its handling of high-salinity feeds makes it a strong candidate for desalination where energy efficiency matters.

Every FO500 system is built by AMPAC USA to the same standard applied across its product line: high-grade materials and components chosen for durability and performance, assembled under stringent quality control from design through production. That engineering discipline is intended to deliver consistent performance, minimal maintenance, and a long operational lifespan for water treatment infrastructure.
