Abstract

This article concerns the questions of complex experimental-theoretic researches of complicated chemical-engineering procedure of electrochemical system of reclamation of working polyphase medium. The work is aimed at creation of methods of design calculations for electrochemical system of water reclamation for space purpose and methods of operation for structure working environment and ways for process and intensification of mass transfer applied to water reclamation systems for complexes supporting the life activity at space station. There were defined the optimal ranges of amper density 0,001 — 0,005 A/cm2, the volume in and out channel, of mixing basin and consumption of working blend in range of Reynolds' s numbers 1—10 also the numbers of electro dialysis cells which provide the required level of working environment purification. The experimental researches have proved the chosen option of operating-technologic characteristics.

Keywords:
