Dynamic Operation of Batch Reverse Osmosis and Batch Pressure Retarded Osmosis
Industrial & Engineering Chemistry Research, 2020Optimal control theory is applied to dynamic operation of batch reverse osmosis (RO) for seawater desalination and batch pressure retarded osmosis (PRO) for power generation. It is proved that the water flux should be constant during the entire operation in order to minimize specific energy consumption (SEC) in RO or to maximize specific energy ...

Natural organic matter fouling in pressure retarded osmosis
Journal of Membrane Science, 2013Fouling is one of the major challenges to be solved in order to commercialise osmotic power generation by pressure retarded osmosis (PRO). This paper deals with natural organic matter (NOM) fouling. The impact of i.a. NOM concentration and ionic strength in the freshwater feed have been investigated for five different types of PRO membranes by ...

Dual Stage Pressure Retarded Osmosis: Potential and Applicability
Qatar Foundation Annual Research Conference Proceedings Volume 2018 Issue 1, 2018A dual stage PRO process has been proposed for power generation from a salinity gradient across a semi-permeable membrane. Both closed-loop and open-loop dual stage PRO system were evaluated using 2 M NaCl and Dead Sea as draw solutions, whereas the feed solution was either fresh water or seawater. The impact of feed salinity gradient resource and feed
