Summary:This work was aimed at studying the transport and selective characteristics of nanofiltration membrane of the OPMN-K type with respect to solutions contained catamine AB and amine oxide for development of promising systems of water regeneration as well as at evaluating the effect of the concentrations of solutions and working pressure of the regeneration unit on these characteristics. It is found that the selectivity of membrane with respect to the solutions contained the single constituents (catamine AB or amine oxide) considerably differed from the selectivity of membrane with respect to solution containing the mixture of catamine AB and amine oxide. Studies of this membrane give the satisfactory results in transport and selective characteristics of all tested solutions excluding the solution containing catamine AB with low concentrations. The obtained results indicate that nanofiltration may be considered as a perspective step of reclamation of sanitary-hygienic water in space flight environments.
