Experimental comparison of direct contact membrane distillation (DCMD) with vacuum membrane distillation (VMD)

Desalination and Water Treatment, 2013
Abstract Membrane distillation (MD) is a thermally driven membrane process using porous hydrophobic membranes. MD has been investigated as an alternative desalination technology due to its advantages over multi-stage flash (MSF) and reverse osmosis (RO).

Analysis and Experimental Study on Water Vapor Partial Pressure in the Membrane Distillation Process

Membranes, 2022
In membrane distillation, the vapor pressure difference is the driving force of mass transfer. The vapor pressure is generally assumed by the saturation pressure and calculated by the Antoine equation.

Modelling of vacuum membrane distillation [PDF]

Journal of Membrane Science, 2013
Abstract A new method of measuring the properties of hollow fibre membranes for modelling purposes was developed. Measuring the gas permeability as a function of membrane length and extrapolating to zero length provided enough membrane material information for modelling the flux.

The Potential of Membrane Contactors in the Pre-Treatment and Post-Treatment Lines of a Reverse Osmosis Desalination Plant

Separations, 2023
The flexibility of membrane contactors (MCs) is highlighted for a reverse osmosis (RO) desalination plant. MCs are applied as pre-treatment for the oxygen removal and the pH reduction of seawater, also as post-treatment for the pH increase of the RO ...
