Channeled coolant plate: a new method to enhance freshwater production from an air gap membrane distillation (AGMD) desalination unit

Air gap membrane distillation (AGMD) desalination process incorporates phase change and transport of vapor from saline water through a hydrophobic membrane and an air gap due to difference in vapor pressure across the membrane and a coolant plate. In this study, an attempt was made to observe the...
