TLDR
In this article, the experimental results of counter current flow air gap membrane distillation experiments are presented and compared with predictive model calculations, and the results show that the previous developed predictive model, with membrane parameters determined from gas permeation experiments, describes correctly the dependence of water vapour flux on temperature level, temperature difference, air gap total pressure, hot water flow and membrane type.About:

Desalination by Membrane Distillation: A Parametric Study
Fawzi Banat,Jana Simandl +1 more
TL;DR: In this article, an air-gap module with built-in condensing surface was used for conducting experiments on polyvinylidene fluoride flat membrane sheets and the quality of the permeate, quantified by conductivity measurements, and the percolation flux were monitored as the feed temperature, feed flow rate, cooling temperature, and cooling water flow fate were varied.

The efficient use of energy in membrane distillation
TL;DR: In this paper, the transport processes in Membrane Distillation (MD) are described by reformulation of the conventional theories of heat and mass transfer, and a preliminary economic analysis shows that under some conditions MD is competitive with RO for production of distilled or potable water for industrial or arid-zone use.
