Abstract: Membrane Materials for Desalination and Wastewater Reuse

Water scarcity is one of the greatest global crises of our time. Increasing water supply beyond what is available from the hydrological cycle can be achieved by seawater desalination and wastewater reuse. Highly effective, low-cost, robust membrane-based technologies for desalination and wastewater reuse are needed, with minimal impact on the environment. However, progress in current state-of-the-art water purification membranes has been limited. We will discuss the state-of-the art of existing membrane technologies for water purification and desalination, highlight their inherent limitations, and establish the critical needs for next-generation membranes. We will then critically analyze recent research efforts to (i) lower energy consumption for water desalination by improving membrane water permeability, (ii) reduce the cost of water desalination via increased water-salt selectivity, and (iii) enhance membrane solute-solute selectivity for applications other than water desalination.
