Abstract: A material for introducing inorganic elements into water, the material including a carrier and a plurality of inorganic compounds that are sparingly soluble in water, wherein the carrier is an organic ion-exchanger having a porous structure in the air-dry state. The organic ion-exchanger reacts with the sparingly soluble compounds such that the sparingly soluble inorganic compounds are contained in pores of the organic ion-exchanger with a ratio of the ion-exchanger to the sparingly soluble inorganic compounds being 35-90:10-65 percent by weight.

Abstract: A method for water recovery from the atmosphere of a habitable pressurized module laden with water vapors released by the inhabitants of said pressurized module, comprising the steps of condensing vapor to produce a gas-liquid mixture, filtering said mixture, carrying out catalytic oxidation of undissociating organic compounds contained in the gas-liquid mixture into dissociating ones by means of a metal-carbon catalyst containing at least one metal of the platinum group, separating condensate from said mixture, sorption-purification of condensate by passing it through activated carbon and ionites followed by disinfection, mineralization and preservation of purified condensate. The system for realization of said method comprises a successively arranged means for condensation of water vapors, a filter, a catalytic oxidation reaction vessel, a condensate separation unit, a sorption purification unit and a water conditioning unit.
