Concentration of cranberry juice by osmotic distillation process
Journal of Food Engineering, 2015Abstract An osmotic distillation (OD) system was implemented to concentrate cranberry juice at laboratory scale. The experimental setup allows the circulation of cranberry juice ( Vaccinium macrocarpon Ait .) and an osmotic agent with flow rates varying from 0.5 to 1.5 L min −1 at temperatures between 30 and 40 °C. The osmotic agent selected in this

Separation and Purification Technology, 2007
Abstract In the current study osmotic membrane distillation (OMD) was applied to reconcentrate osmotic dehydration spent sucrose solutions. The OMD experiments were performed at constant temperature of 35 °C, using PTFE membrane. During the experiments sucrose solutions of different concentrations (30–60 °Brix) were partially dehydrated using 50% (w ...

Suppression of Osmotic Distillation in Gas Membrane Processes
Separation Science and Technology, 2008Suppression of osmotic distillation of water is important for the commercial scale application of gas membranes. We have equalized the water vapor pressure on either side of the membrane by increasing the temperature of the stream with the lower water vapor pressure. The experimentally determined temperature gradient is many times larger than predicted

A comprehensive review of membrane distillation and osmotic distillation in agro-food applications
2020Membrane 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,

Osmotic Membrane Distillation - A Brief Review
International Journal of Food Engineering, 2006In recent years, osmotic membrane distillation is gaining importance as an attractive/ complementary athermal membrane process. Osmotic membrane distillation is having potential to concentrate the biomolecules/liquids to a very high level under mild operating condition, without product damage.

New opportunities for osmotic membrane distillation
Membrane Technology, 2006This article discusses a potential large-scale application for osmotic membrane distillation — a relatively new membrane technology. More specifically, commercial opportunities for the technology are discussed using an example of NaCl brine re-concentration in the chlor-alkali industry.

Osmotic Distillation for the Recycle of Spacecraft Wastewater
40th International Conference on Environmental Systems, 2010The osmotic distillation (OD) system is being developed as spacecraft water treatment system capable of recycling urine and humidity condensate to potable standards. This technology uses osmotic distillation followed by reverse osmosis (RO). OD is an isothermal distillation process.

The problem of membrane characterization for the process of osmotic distillation [PDF]
Desalination, 2001 Abstract The membrane used in the process of osmotic distillation (OD) is often considered passive as it simply provides a support for the vapour—liquid interfaces where evaporation and condensation take place and does not introduce any selectivity. However, the membrane is a major component of the system, not only because it constitutes one of the ...
