Variation of Flux in Membrane Distillation

Simplified flux prediction in direct-contact membrane distillation using a membrane structural parameter

• Membrane structural parameters were evaluated for use in predicting water flux. • Membrane constant containing non-coupled membrane properties was introduced. • Membrane constant requires simple measurements and inexpensive analytical equipment. • Membrane constant correlates well with experimental water flux. • Comprehensive collection of MD membrane properties and water fluxes made availabl...

A Comprehensive Review of Membrane Distillation and Osmotic Distillation in Agro-Food Applications

Membrane distillation (MD) and osmotic distillation (OD) are emerging athermal processing techniques of great interest in agro-food production where the most part of products is sensitive to thermal treatments. With respect to conventional methods, MD and OD are competitive alternatives, able to work in an environmental-friendly and cost-efficient way, for preserving the nutritional and sensori...

The Application of Membrane Distillation for Broth Separation in Membrane Bioreactors

The possibility of applying membrane distillation to support the fermentation process was investigated. The capillary polypropylene membranes were assembled in the membrane modules. The studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. The performance o...

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...
