Scaling Reduction in Carbon Nanotube-Immobilized Membrane during Membrane Distillation

A scaling mitigation approach during direct contact membrane distillation

Membrane scaling during the treatment of aqueous solutions containing sparingly soluble salts by direct contact membrane distillation (DCMD) was investigated. The results reveal that membrane scaling caused by CaSO4 was more severe than that by CaCO3 or silicate. However, under the experimental condition used in this study and at feed and distillate temperature of 20 C and 40 C, respectively, C...

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...
