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...
متن کاملPreliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement
The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
متن کاملHybrid 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...
متن کاملVacuum membrane distillation on a microfluidic chip.
A multilayered microfluidic chip used for vacuum membrane distillation is designed, fabricated and tested by rectification of a water-methanol mixture.
متن کاملEffect of Filtration and Particulate Fouling in Membrane Distillation
Fouling and scaling in membrane distillation (MD) is one of the significant barriers to its continued growth. Fouling in MD blocks the pores, causing a decline in permeate flux, and may eventually lead to wetting of a hydrophobic membrane by the saline feed, contaminating the permeate. Many previous studies on MD have observed that while MD is more fouling resistant than reverse osmosis (RO), i...
