RecovOAR™ is an integrated RO–OARO process designed to maximize freshwater recovery from high-salinity, low fouling streams by combining conventional reverse osmosis (RO) with osmotically assisted reverse osmosis (OARO). The system removes bulk water through RO, then continues extracting water from elevated-salinity brines using OARO—extending recovery beyond conventional limits while reducing overall concentrate volume.

This integrated approach enables stable operation under high osmotic pressures while improving overall efficiency, making RecovOAR™ well-suited for high-recovery applications, brine minimization, and ZLD-aligned treatment systems.

How Does RecovOAR™ Use OARO?

Osmotically assisted reverse osmosis (OARO) is a membrane process that combines hydraulic pressure with an osmotic gradient to sustain water flux at high salinities. By offsetting feed-side osmotic pressure with a controlled draw stream, OARO enables continued recovery where conventional RO becomes limited.

This allows for deeper brine concentration, improving overall system efficiency and making OARO a critical component in advanced, high-recovery treatment trains.
