Activation of the Processes of Scavenging in the Revitalization Water Systems using Electrochemical Principles 2001-01-2247

One of the vital issues being solved at development of self-contained ecosystems (of space stations, ground-level and underwater complexes) to provide the crew with the water from products of habitability.
To solve this problem the revitalization water systems, using electrochemical principles, servicing module of 3 persons and capable of independent operation during 3 months, have been designed.
The results of the mass exchange research are summarized by way of driving forces activity ratio that takes into account a variable input impurity concentration, as well as the ratio of phasal interaction that relates to the speed of inflow and of the electric current.
Given below are the ways offered to activate the processes of removing impurities from water:
  • by creation of variable electric field ensuring the interaction between OHions and eliminated components in the field of maximum current,
  • by sectioning the welding rod with different current density and separation of the areas of the fallout of bound ions with appropriate solubility product.
The above ways allow to reduce the power consumption of the system by 20 %.
This is the survey of a general mathematical model of the revitalization water systems using electrochemical principles and including differential equations of the mass exchange, momentum and temperature.
