METHOD FOR REVERSE OSMOSIS TREATMENT OF SANITARY AND HYGIENIC WATER IN CLOSED CIRCUIT IN GRAVITY-FREE ENVIRONMENT Russian patent published in 2017 - IPC C02F1/44 

FIELD: aviation.

SUBSTANCE: method of reverse osmosis treatment of sanitary and hygienic water from a detergent and impurities in gravity-free environment is based on the use of membrane technology, in which the source water is supplied to the receiving source water tank, from where it is pumped to the reverse osmosis filter element, wherein it is possible to return the concentrate to the circulation circuit, contaminated water circulating in a circuit with constant volume tank is simultaneously filtered through the reverse osmosis membrane, and circulation circuit of purified water source is made up with gradual increase of concentration up to the maximum allowable degree of purification and providing clean water recovery ratio, determined by the ratio of these concentrations.

EFFECT: increased degree of water extraction during continuous process of regeneration in gravity-free environment, ensuring a long service life.
