Vapour Transport Mechanism in Osmotic Distillation Process

International Journal of Food Engineering, 2009
Osmotic distillation experiments were carried out using pure water as feed in order to investigate the mass transfer mechanism in the membrane. In the experiment, the hollow fibre modules with packing density of 30.6 and 61.2% were employed. The Dusty gas model was used to estimate the transport of vapour through the membrane. The results revealed that

Membrane osmotic distillation and its mathematical simulation

Desalination, 2001
Abstract 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.

Osmotic distillation applying potassium pyrophosphate as brine

Journal of Food Engineering, 2018
Abstract Potassium pyrophosphate was applied as stripping solution in osmotic distillation of fruit juices. The permeate ranged between 0.56 and 1.45 kg/m2h, being more sensitive to the variation of the feed temperature. After pre-saturating the experimental apparatus, no significant effect on the degradation of ascorbic acid was found and the losses

Concentration of clarified kiwifruit juice by osmotic distillation

Journal of Food Engineering, 2007
This study was undertaken in order to evaluate the potential of the osmotic distillation (OD) process for concentrating clarified kiwifruit juice on laboratory scale, taking into account the impact on the product quality especially in terms of ascorbic acid content and total antioxidant activity (TAA). The performance of the OD process in terms of flux

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

2020
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,

Coupled Phenomena Membrane Distillation and Osmotic Distillation through a Porous Hydrophobic Membrane

Separation Science and Technology, 1995
Abstract Water transport in the vapor phase through a porous hydrophobic membrane has been studied in different experimental situations. Pure water and/or different aqueous solutions of sodium chloride, ranging from 0.5 to 5 mol/L, were employed on both sides of the membrane.

Concentration of cranberry juice by osmotic distillation process

Journal of Food Engineering, 2015
Abstract 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

Application of osmotic membrane distillation for reconcentration of sugar solutions from osmotic dehydration

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, 2008
Abstract 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.

Osmotic Distillation for the Recycle of Spacecraft Wastewater

40th International Conference on Environmental Systems, 2010
The 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.
