Abstract: To enhance the seawater desalination energy efficiency forward osmosis-reverse osmosis (FO-RO) hybrid system has recently been developed. In this process, the FO "pre-treatment" step is designed to dilute the seawater (SW) with reclaimed wastewater (WW) before the desalination step, thereby reducing the energy demand for the SWRO process. However, membrane fouling is a major issue that needs to be addressed. Proper selection of suitable WWs is necessary before proceeding with largescale FO-RO desalination plan…
