A Comprehensive Review of Membrane Distillation and Osmotic Distillation in Agro-Food Applications

Authors

Abstract:

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 sensorial attributes of processed foods, in agreement with the increased expectations of consumers and producers. This review will provide an overview of the current status and recent developments in the use of MD and OD in agro-food applications. Theoretical aspects and specific applications in the field of fruit juice concentration, milk and dairy industry, wine dealcoholization and agro-food waste processing, are presented and discussed. The integration of these processes with other membrane operations within the logic of the process intensification strategy is also evaluated in order to overcome specific challenges for a sustainable industrial development.

A Review on Applications of Membrane Distillation (MD) Process for Wastewater Treatment

The growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. Various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (MD) process, as a promising separation technology, has recently gained more attention. The MD process is a non-isothermal membrane-based separati...

Membrane Distillation: Principles, Applications and Perspectives

Membrane Distillation (MD) is a membrane-based operation able to give 100% theoretical ions rejection and to efficiently work with high concentrated brines. Both features make MD of interest for the purification of wastewater, the production of ultra-pure water and the concentration of brines produced in desalination. MD, also integrated with other membrane operations, can be a valuable way to ...

The long-term studies of osmotic membrane distillation

The results of osmotic membrane distillation carried out for 2.5 years were presented in this work. The influence of the process conditions, such as temperature and brine concentration on the permeate flux, was investigated. The saturated NaCl solutions and distilled water were used as a stripping solution and feed, respectively. A continuous regeneration of stripping solution was conducted usi...

Critical review of membrane distillation performance criteria

The number of published papers about membrane distillation (MD) has been growing exponentially and many evaluation and performance criteria are used to measure it; but, there is no established tradition or evaluation standard for them. This makes the evaluations difficult to compare, or even incomplete. This paper presents therefore a comprehensive critical review and clarification of the major...

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 ...
