Hollow fiber membrane-based air gap membrane distillation
Membrane Distillation (MD) is a thermally-driven separation process. In this research, desalination of 1 % NaCl solution is achieved by one type of MD namely, Air Gap Membrane Distillation (AGMD). The characteristics of AGMD are evaluated by using a hollow-fiber-set-based compact device. Hot brine …

Conversion of Saline Water to Fresh Water Using Air Gap Membrane Distillation (AGMD)
Membrane distillation (MD) is a combination of evaporation of water from saline solution and diffusion of vapour through a hydrophobic membrane. The driving force is the vapour pressure difference created by temperature difference across the membrane. With development of hydrophobic membranes at a …

Investigations on Air-cooled Air Gap Membrane Distillation and Radial Waveguides for Desalination
This thesis presents investigations on air-cooled air gap membrane distillation for desalination and the application of radial waveguides based on total internal reflection for solar thermal desalination. Using an air-cooled design for an air gap membrane distillation (AGMD) process may result in …

Visualization and measurement of filmwise and dropwise air gap membrane distillation at varied module inclination angle and gap spacer Orientation
… water desalination technologies such as air gap membrane distillation (AGMD). While the system is dominated by heat and mass transfer resistances in the air gap specifically, very little is known about the impact of variations in the air gap, including air gap spacers and module tilting. …

Theoretical and experimental investigation of membrane distillation
Invented in the 1960s, membrane distillation is an emerging technology for water treatment attracting more attention since 1980s. There are four configurations of membrane distillations including air gap membrane distillation (AGMD), direct contact membrane distillation (DCMD), sweep gas membrane …

Development of energy efficient membrane distillation systems
Membrane distillation (MD) has shown potential as a means of desalination and water purification. As a thermally driven membrane technology which runs at relatively low pressure, which can withstand high salinity feed streams, and which is potentially more resistant to fouling, MD could be used for …
