Abstract
The recent advances and progress in pressure retarded osmosis-membrane distillation (PRO-MD) hybrid systems in terms of osmotic heat engines, newly devised configurations, and current drive to use various feed water types such as reclaimed water, treated wastewater effluent, and rain water are presented in this chapter. This review is a short review because research on PRO-MD systems is limited and the progress in this area has only been recorded recently. Newly reported performance values are also provided. A hybrid system that combines a multistage vacuum MD with PRO has shown capability to continuously produce the distillate and a very concentrated brine that can be used as the draw solution in PRO. Closed loop systems have also shown improved performance indices related to power density and energy efficiency in recent studies. More recently, PRO-MD hybridized with reverse osmosis (RO) in MD-PRO-RO systems have shown the potential to offer more sustainable osmotic power recovery and lower environmental footprints.
