Solar thermal powered desalination: membrane versus distillation technologies

Multiple Effect Distillation (MED) is generally considered to be the desalination technology most suited to integration with concentrating solar thermal collectors on a medium to large scale. However the cost and energy requirement of Reverse Osmosis (RO) have fallen significantly in recent years, so that solar thermal powered RO deserves consideration. We compare commercial desalination proces...

On Designing of Membrane Thickness and Thermal Conductivity for Large Scale Membrane Distillation Modules

Membrane distillation has the potential to concentrate solutions to their saturation level, thus offering the possibility to recover valuable salts from the solutions. The process performance and stability, however, is strongly dependent upon the features of membranes applied. In addition, several other parameters, membrane thickness and thermal conductivity significantly affect the process per...

Recent Progress on Improving the Sustainability of Membrane Fabrication

Although the membrane process is recognized as a green technology and is considered as a key player in the process intensification movement, it is not widely known that the fabrication of membrane itself generates significant amount of waste. With the growing membrane market, more efforts must be placed on improving the sustainability of membrane fabrication such as replacing toxic organic solv...

Membrane Distillation for Water Recovery and Its Fouling Phenomena

The total volume of water on Earth is circa 300 million cubic miles, with close to 98.0% being salt water and the remaining 2.0% fresh water. It has been increasingly more challenging to harvest fresh water from surface water, seawater and even from wastewater due to the combination of factors, viz. burgeoning population growth, rapid industrialization and climate change. Recently, membrane dis...
