Membrane distillation

Membrane distillation (MD) has gained significant regard from industrial and academic perspective in recent years, thus the frequency of publications related to the field has greatly accelerated. New perspectives have boosted the research activities related to deeper understanding of heat and mass tra

Theoretical and experimental studies of direct contact membrane distillation (DCMD) using commercially flat sheet hydrophobic polyvinylidene fluoride (PVDF) membrane were investigated to remove boron from simulated and natural seawater. Mass transfer mechanism and theoretical flux were determined using

Direct contact membrane distillation (DCMD) module was operated with three flat sheet commercial membranes (PTFE/PP 1.0, PTFE/PP 0.45, and PTFE/PE 0.45) under various operating conditions. High flux was observed when the PTFE/PP 1.0 membrane was used and there was no membrane wetting when the feed con

• We developed a portable solar-driven desalination system for producing potable water. • A stand-alone system which utilizes solar energy by combining PV/thermal collectors. • The system uses Vacuum-Multi Effect Membrane Distillation (V-MEMD) process. • We also reported some small-scale test result

Membrane distillation (MD) is a hybrid thermal-membrane desalination process that uses low-grade waste heat and hydrophobic membrane to produce high quality distillate. The MD process can treat highly saline brines that other conventional desalination processes cannot treat. These unique features of

In many places world wide drinkable water is already a scarce good and its lack will rise dramatically in the future. Missing energy sources and no grid connections complicates the use of standard desalination techniques in these places. Fraunhofer ISE develops solar thermally driven compact desalin

The possibility of olive mill wastewaters (OMW) treatment and concentration by membrane distillation has been investigated. The objective is to obtain pure water and a concentrate containing high amounts of polyphenols, which can be extracted later. Two types of commercial membranes, polytetrafluoro

This paper deals with the MEDESOL (Seawater Desalination by Innovative Solar-Powered Membrane Distillation System) project, partially supported by the European Commission under the Horizontal Programme “Global Change and Ecosystems (Global 4)”. Despite the advantages of solar membrane distillation (

Nowadays, more than 110 cities of China confront the serious problem of fresh water shortage, and more than 70% of the rivers and lakes are contaminated to some extent. About 38 million people are depending on brackish water for life. Desalination of seawater and brackish water is one of the ways to

In this study the applicability of membrane distillation (MD) was investigated to produce black-currant juice concentrate. For the experiments enzyme treated, pre-filtered by microfiltration and pre-concentrated by reverse osmosis fruit juice was applied. The measurements were carried out in a hollo
