Energy and Resources Recovery from Reverse Osmosis Desalination Concentrate
The overarching goal of this research project is to develop technologies for beneficial salinity management. Specifically, the project focuses on the energy and resources recovery from reverse osmosis (RO) desalination concentration, which can reduce the cost associated with desalination operation and minimize the environmental impact associated with the disposal of desalination concentrate. Th...
متن کاملRecent Advances in Osmotic Energy Generation via Pressure-Retarded Osmosis (PRO): A Review
Global energy consumption has been highly dependent on fossil fuels which cause severe climate change and, therefore, the exploration of new technologies to produce effective renewable energy plays an important role in the world. Pressure-retarded osmosis (PRO) is one of the promising candidates to reduce the reliance on fossil fuels by harnessing energy from the salinity gradient between seawa...
متن کاملComparison of energy efficiency and power density in pressure retarded osmosis and reverse electrodialysis.
Pressure retarded osmosis (PRO) and reverse electrodialysis (RED) are emerging membrane-based technologies that can convert chemical energy in salinity gradients to useful work. The two processes have intrinsically different working principles: controlled mixing in PRO is achieved by water permeation across salt-rejecting membranes, whereas RED is driven by ion flux across charged membranes. Th...
متن کاملThe Effect of Osmotic Dehydration on Reverse Osmosis Membrane Performance
Akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. The extent of consequent changes (in appearance; decrease in linear dimension, water flux and salt rejection) are dependent on the salt concentration. These observations are correlated with the expected morphological changes taking place duri...
متن کاملInfluence of natural organic matter fouling and osmotic backwash on pressure retarded osmosis energy production from natural salinity gradients.
Pressure retarded osmosis (PRO) has the potential to produce clean, renewable energy from natural salinity gradients. However, membrane fouling can lead to diminished water flux productivity, thus reducing the extractable energy. This study investigates organic fouling and osmotic backwash cleaning in PRO and the resulting impact on projected power generation. Fabricated thin-film composite mem...
