Suppression of Osmotic Distillation in Gas Membrane Processes
Separation Science and Technology, 2008Abstract 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.

Concentration and temperature polarization effects during osmotic membrane distillation
Journal of Membrane Science, 2008Abstract Pineapple juice is one of the popular fruit juice due to its pleasant aroma and flavor. Concentration of clarified pineapple juice was carried out by osmotic membrane distillation in a plate and frame membrane module. Concentration and temperature polarization effects are found to have significant role on flux reduction during osmotic ...

Pomegranate juice concentration using osmotic distillation with membrane contactor
Separation and Purification Technology, 2019Abstract This study aims at evaluating the effect of fouling on the performance of polypropylene hollow fiber membrane contactor with feed-in-shell flow configuration for the concentration of pomegranate juice through osmotic distillation (OD). The juice was concentrated to 52.0 ± 0.3°Brix, reaching a maximum flux of 1.053 kg.m−2.h−1 at a temperature

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 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 ...

Modelling of water transport in osmotic distillation using asymmetric membrane
Journal of Membrane Science, 2000Abstract Several models commonly employed to represent the mass transfer in osmotic distillation (OD) systems are applied to the results of pure water OD experiments carried out with two commercial asymmetric porous membranes. Molecular and Knudsen diffusion mechanisms are tested to model the vapour transport across the membrane.

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.

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.
