FIELD: technological processes.
SUBSTANCE: invention is related to technology of hydrogen isotopes separation, namely, detritisation of waste water by method of chemical isotopic exchange of hydrogen with water on heterogeneous catalysts. Method includes isotopic exchange between water and hydrogen in multi-stage counterflow separating column, which comprises lower unit of flows circulation or electrolytic cell. Separating column comprises serially connected contact devices of membrane type, which are installed in horizontal plane.
EFFECT: reduced hydraulic resistance of column and its improved throughput efficiency.
