Hybrid Applications of Pressure Retarded Osmosis (PRO), Reversed Electrodialysis (RED), and Capacity Mixing (CapMix) with Seawater Reverse Osmosis Process (SWRO)
Exploitation of sustainable and environment-friendly energy resources is highly required to resolve energy shortage. Recently, salinity gradient power (SGP) is considered as a feasible candidate with high potential to substitute fossil fuels due to its benefits: less periodic, abundance, and no emission of carbon dioxide. In this presentation, SGP processes such as pressure retarded osmosis (PRO) Reversed Electrodialysis (RED), and Capacity Mixing (CapMix) were reviewed with its mechanism, limitations, and available applications. For instance, in a PRO system, water permeates through semi-permeable membrane from feed solution to draw solution, and energy is generated by depressurizing the permeated flow through hydro turbine. Models for understanding of its mechanism and for improving of its performance were overviewed. In addition, applications of seawater reverse osmosis (SWRO), wastewater treatment (WWT), and PRO hybrid process were introduced to develop new water-energy nexus processes. The SWRO-PRO hybrid process and SWRO-PRO-WWP hybrid process can contribute on opening an insight to reduce the total energy consumption in SWRO plant as well as to apply the SGP energy to other engineering fields.
