Understanding Membrane Distillation and Osmotic Distillation [PDF]
, 2017 This book addresses principles and practical applications of membrane distillation and osmotic distillation, separation technologies which are gaining increasing attention due to their advantages over conventional concentration processes. Addresses membrane and osmotic distillation, two closely related and novel processes that offer several advantages ...

Mass transfer in osmotic membrane distillation [PDF]
Journal of Membrane Science, 2006 Osmotic membrane distillation is a novel athermal membrane process that facilitates the maximum concentration of liquid foods under mild operating conditions. In the present study, the effect of various process parameters such as type, concentration and flow rate of the osmotic agent; type (polypropylene membranes) and pore size (0.05 and 0.2 μm) of ...

Suppression of Osmotic Distillation in Gas Membrane Processes [PDF]
Separation Science and Technology, 2008 Suppression 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

Osmotic MD and other membrane distillation variants
Journal of Membrane Science, 2005A literature survey concerning the osmotic membrane distillation was presented. This process is discussed and compared with other types of membrane distillation, particularly with direct-contact membrane distillation. A critical evaluation of the process principles and parameters was included in this literature review.

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.

Acoustic field-assisted osmotic membrane distillation [PDF]
Desalination, 2002 Abstract Osmotic membrane distillation (OMD) is a novel membrane process that facilitates the concentration of aqueous solutions under mild operating conditions. The main drawback of OMD, like any other membrane process, is relatively low flux. In the present work acoustic field has been applied for the enhancement of transmembrane flux.

Membrane osmotic distillation and its mathematical simulation
Desalination, 2001Abstract A membrane distillation process with brine circulated in the cold side was developed. This process combines the ordinary membrane distillation (MD) with the osmotic distillation (OD), and is therefore called membrane osmotic distillation (MOD). Comparisons of MOD with MD and OD were carried out.

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 ...

The heat and mass transfer phenomena in osmotic membrane distillation
Desalination, 2002Abstract This paper presents an experimental procedure to analyse the heat and mass transfer phenomena involved in osmotic membrane distillation and to measure the related parameters. Use is made of a module containing a few membrane sheets in co-current flow configuration.
