SolarSpring Publications: Techno-economic comparison of membrane distillation and MVC in a zero liquid discharge application

Abstract Membrane distillation (MD) is a thermally driven membrane process for the separation of vapour from a liquid stream through a hydrophobic, microporous membrane. However, a commercial breakthrough on a large scale has not been achieved so far.Specific developments on MD technology are required to adapt the technology for applications […]

SolarSpring Publications: Air gap membrane distillation for hypersaline brine concentration

Operational analysis of a full-scale module – New strategies for wetting mitigation Abstract Membrane distillation (MD) is a thermal separation process which possesses a hydrophobic, microporous membrane as vapor space. A high potential application for MD is the concentration of hypersaline brines, such as e.g. reverse osmosis retentateor other saline effluents to be concentrated to a near saturation level with […]
