Heat and mass transfer analysis in air gap membrane distillation process for desalination

Bhausaheb L. Pangarkar and Mukund G. Sane

Abstract

The air gap membrane distillation (AGMD) process was applied for water desalination. The main objective of the present work was to study the heat and mass transfer mechanism of the process. The experiments were performed on a flat sheet module using aqueous NaCl solutions as a feed. The membrane employed was hydrophobic PTFE of pore size 0.22

Key Words
