Abstract

The scarcity of potable water has become an increasingly urgent global challenge. One of the key technologies for freshwater treatment is reverse osmosis (RO). However, the widely used single-stage reverse osmosis configuration produces a high volume of concentrate, which is typically discarded, thereby increasing raw water demand and reducing overall system efficiency. This study aims to enhance the efficiency of the reverse osmosis system through the application of a triple-stage configuration, where the concentrate generated in the initial stages is recycled and reprocessed. The main focus of this research is to evaluate the improvement in permeate production while calculating the recovery rate efficiency of the triple-stage system compared to the single-stage system. The findings show that the triple-stage configuration significantly reduces concentrate production, increases permeate output, and achieves a higher recovery rate efficiency. Compared to the single-stage system, the triple-stage system demonstrates optimal utilization of raw water resources. These results provide a strategic contribution to the development of more sustainable and environmentally friendly water treatment technologies, offering a practical solution to address the global water crisis.
