OSMOTICALLY ASSISTED REVERSE OSMOSIS (OARO)

Osmotically Assisted Reverse Osmosis(OARO) is a reverse osmosis technology specifically designed to concentrate clean brine streams where thermal sources are not available.

Membranes used in standard reverse osmosis can stand maximum pressure of 80 bars and capture brine with 65,000 to 70,000 ppm concentration. Once that limit is reached, membranes can no longer separate additional brine from the water. Integrated with standard reverse osmosis, Hyrec’s OARO technology increases the concentration of brine captured to 250,000 ppm, with only 70 bars of pressure. More water is acquired, less energy is consumed, and impact on the environment is minimized.

Hyrec’s proprietary OARO technology has a wide range of industrial water and wastewater applications. Hyrec’s OARO can be integrated with conventional systems (e.g. filtration, reverse osmosis, forward osmosis, ion exchange, crystallizator) to generate high-quality concentrate with minimum energy consumption.

How OARO Works

In a reverse osmosis system, water flux is driven by exceeding the osmotic pressure difference across a semi-permeable membrane with an applied hydrostatic pressure to maintain water flow. The osmotic pressure difference across a membrane can be reduced by keeping the saline solution in both sides by giving the concentrate partially back to system.
