ON O C (57) : The object of the invention is to provide a system and process that enables product recovery from aqueous solutions containing salts or low molecular weight solutes such as ethanol at high recovery ratio, low osmotic pressure differential (OPD) and low energy consumption compared to current methods. Particular applications of the invention include production of potable water from water sources with high salt content such as sea water, brackish water or wastewater. The system and process related to the present reduced-pressure reverse osmosis (REPRO) invention described here achieves the reduction in the SEC, a reduction in the OPD, and an increase in the potable water recovery via a novel multistage hybrid RO-NF process technology.
