Heat Recovery Characteristics of Membrane Distillation.

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...

Improving Nanofiber Membrane Characteristics and Membrane Distillation Performance of Heat-Pressed Membranes via Annealing Post-Treatment

Electrospun membranes are gaining interest for use in membrane distillation (MD) due to their high porosity and interconnected pore structure; however, they are still susceptible to wetting during MD operation because of their relatively low liquid entry pressure (LEP). In this study, post-treatment had been applied to improve the LEP, as well as its permeation and salt rejection efficiency. Th...

Desalination by Membrane Distillation

Hybrid membrane-distillation processes

This work focuses on modelling, simulation and process analysis of hybrid membrane separations namely on distillation and pervaporation. Such hybrid process can be applied for the separation of multicomponent azeotropic mixtures without the use of entrainer. Its application is illustrated by the separation of a non-ideal ternary mixture of acetone, isopropanol and water. The extended abstract d...

Fluorosilaned-TiO2/PVDF Membrane Distillation with Improved Wetting Resistance for Water Recovery from High Solid Loading Wastewater

Membrane distillation (MD) has emerged as an important technology for applications in industries such as seawater desalination and wastewater treatment due to its low energy requirement and theoretically low fouling propensity. However, the main obstacle to obtain high separating efciency in MD lies on the availability of porous hydrophobic membrane that can withstand p...
