Reverse osmosis (RO) is now the most ubiquitous technology for desalination, with numerous seawater ROplants being built in water-stressed countries to complement existing water resources. Despite the developmentof highly permeable RO membranes, energy consumption remains a major contributor to total cost. Forward osmosis(FO) is receiving much attention as a potentially lower energy alternative to RO. However, the draw solution(DS) recovery step in FO requires significant energy consumption. The present study is a modellingapproach, simulating FO and RO desalination under various process conditions and process flow schemesusing the Aspen Plus environment. Results suggest that there is practically no difference in specific energy consumption(SEC) between standalone RO, and FO with nanofiltration (NF) DS recovery; this can be generalised forany pressure-driven membrane process used for the DS recovery stage in a hybrid FO process. Furthermore, evenif any or all of the membranes considered, FO, RO or NF, were perfect (i.e. had infinite permeance and 100%rejection), it would not change the SEC significantly. Hence, any advantage possessed by the FO with NF recoveryprocess derives from the lower fouling propensity of FO, which may reduce or eliminate the need for pretreatmentand chemical cleaning
