MEMBRANE DISTILLATION

Review contains the analysis of membrane distillation (MD) studies. A critical analysis of theoretical and experimental studies of MD is pre sented. A special attention is given to mass transfer mechanism and to influence of various external factors upon peculiarities of the proce ss. The problems of design of modules and devices for the membrane dis tillation are thoroughly considered as well as some practical aspects of pure water obtaining, waste purification and different tecnological solutions concentration by MD. The analysis of advantages and disadva ntages of the MD compared with other membrane methods is given. Biblio graphy - 97 references.
