ConcentratOAR™ is an advanced Forward Osmosis (FO) and Osmotically Assisted Reverse Osmosis (OARO) solution designed to maximize water recovery while concentrating industrial wastewater streams that conventional technologies are limited by. ConcentratOAR™ effectively handles high-fouling, high-organic feedwaters across applications such as industrial wastewater treatment, landfill leachate management, food and beverage concentration, and Zero Liquid Discharge (ZLD).

By leveraging the natural osmotic pressure of FO, ConcentratOAR™ can process streams containing elevated levels of dissolved solids, organics, and other contaminants with reduced pretreatment requirements and reliable long-term operation. The result is a flexible, efficient solution that helps industries reduce waste volumes, recover water, and meet increasingly stringent environmental requirements.

The ConcentratOAR™ Process

ConcentratOAR™ uses a pioneering membrane process called Forward Osmosis (FO) to concentrate brine and recover valuable resources. FO uses a natural osmotic pressure difference to move water across a semipermeable membrane without the high operating pressures required by conventional water treatment technologies. Water is drawn from the feed stream into a concentrated draw solution, leaving salts, nutrients, contaminants, and other impurities behind.

Because FO relies on osmotic pressure rather than high hydraulic forces, it is particularly effective for treating difficult, high-fouling streams while maintaining stable performance and water flux. This makes FO a valuable technology for water recovery, brine concentration, and ZLD applications where efficiency and reliability are critical.
