Membrane-Based Salinity Gradient Processes for Desalination Handbook Two Swansea University chemical engineering academics have written a handbook which reviews current state-of-the-art developments in salinity gradient processes in desalination, one of the most promising technologies to improve energy efficiency in desalination. The impending crisis posed by water stress and poor sanitation represents one of the greatest human challenges for the 21st century, and membrane technology has emerged as a serious contender to confront the crisis on a global scale. Seawater desalination is poised to become one of the main alternative freshwater resources as almost 60% of the worldâs population live less than 36 miles from a seacoast.
