Osmotic distillation and quality evaluation of sucrose, apple and orange juices in hollow fiber membrane contactor

Fabrication and Characterization of Polyetherimide Hollow Fiber Membrane Contactor for Carbon Dioxide Stripping from Monoethanolamine Solution

In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...

Concentration of Colourful Wild Berry Fruit Juices by Membrane Osmotic Distillation via Cascade Model Systems

Fresh juices of colourful wild berries: cornelian cherry, blackthorn, white beam and elderberry are considered as valuable, highly nutritive beverages and characterized by the high level of vitamins and antioxidant capacity. The concentration process of these juices by membrane osmotic distillation was studied, where only water vapour is eliminated, while the heat sensitive, valuable compounds ...

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...
