Theoretical and experimental approaches of liquid entry pressure determination in membrane distillation processes [PDF]
, 2014 Membrane distillation (MD) is a thermally driven separation process that employs a hydrophobic membrane as a barrier for the liquid phase, allowing only vapor phase to pass through the membrane pores. Wetting of membrane pores by liquid streams (i.e. the
