FIELD: chemistry.
SUBSTANCE: device contains a case (1) with a placed inside it hermetic reservoir with changing volume (14), consisting of an upper cylinder of the smaller diameter (5), a lower cylinder of the larger diameter (10) and a flexible envelope (9), placed between them. The upper part of the cylinder with the smaller diameter (5) contains a cavity (4) and a filter (2), above which a hole for the input of light water (3) is located. The volume of the cavity (4) by means of the central channel (7) is connected to the volume of the flexible envelope (9) and by channels (8) with the volume of the cylinder with the larger diameter (10), in which guides (11), rigidly connected to the lower part of the cylinder with the larger diameter (10) are located.
EFFECT: simple and reliable obtaining of tap water purified from heavy deuterium isotopes.
