[The use of nanofiltration for regenerating different types of water for sanitation and hygiene obtained in a hermetically sealed cabin].

Presented are results of evaluating transportability and selectivity of Russian OPMN-K membrane coil nanofilters used in a chamber experiment (project EPOKSI [correction of ECOPSI]-95) to clean washing water containing different detergents. OPMN-K nanofilters were potent to extract no less than 96 to 98% of permeate with the organic selectivity reaching 80 to 90%. The detergent-dependent dynamics of capacity and selectivity and data of analyses of producible permeates and concentrates are reported.
