Insufficiency of development level of questions for the creation of mathematical models of process contact-membrane distillation (CMD) has led to the fact that their development is an urgent task, which solution is devoted work.

The task of the optimization of static operating modes of the installation of the process of contact membrane distillation was considered. The target-factorial analysis of control of the process was made. An approach to the optimization of the installation was offered. There was set the specific cost of the process as the optimality criterion. The numerical analysis of the function of the purpose showed an existence of the isolated local minimum and allowed to determine an optimum of the solution supply speed and the thickness of the membrane.
