During water desalination, membrane distillation (MD) is challenged by the inefficiency of water thermal separation from dissolved solutes, due to its dependence on membrane porosity and thermal conductivity. For instance, ...
(Phys.org) -- As the world population increases and fresh water sources become scarcer, many people will likely rely on technologies that convert salt water to fresh water to meet their most basic needs. Currently, the most ...
(Phys.org) -- Although oceans and seas contain about 97% of Earth’s water, currently only a fraction of a percent of the world’s potable water supply comes from desalinated salt water. In order to increase our use ...
(Phys.org) -- As a rising global population and increasing standard of living drive demand for freshwater, many researchers are developing new techniques to desalinate salt water. Among them is a team of scientists from The ...
A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains ...
