This paper presents a complete dynamic modeling of a membrane distillation process. The model contains two consistent dynamic models. A 2D advection-diffusion equation for modeling the whole process and a modified heat equation for modeling the membrane itself. The complete model describes the temperature diffusion phenomenon across the feed, membrane, permeate containers and boundary layers of...

Membrane Distillation (MD) is a membrane-based operation able to give 100% theoretical ions rejection and to efficiently work with high concentrated brines. Both features make MD of interest for the purification of wastewater, the production of ultra-pure water and the concentration of brines produced in desalination. MD, also integrated with other membrane operations, can be a valuable way to ...

Hybrid separation systems have recently been hailed as one of the inost promising alternatives to conventional capital and energy intensive separation processes. Hybrid separation systems are able to effectively separate inixtures commonly encountered in the fine chemical and pharmaceutical industries that are difficult or impossible to separate by conventional distillation processes due to aze...

In recent decades, membrane-based processes have been extensively applied to a wide range of industrial processes, including gas separation, food industry, drug purification, and wastewater treatment. Membrane distillation is thermally driven separation process, in which only vapour molecules transfer through microporous hydrophobic membrane. At the operational level, performance membrane negat...

The number of published papers about membrane distillation (MD) has been growing exponentially and many evaluation and performance criteria are used to measure it; but, there is no established tradition or evaluation standard for them. This makes the evaluations difficult to compare, or even incomplete. This paper presents therefore a comprehensive critical review and clarification of the major...
