FIELD: chemistry.SUBSTANCE: invention relates to systems for UV-decontamination of sewage and drinkable water. System of UV-decontamination contains UV-irradiators, placed in symmetrical with respect to longitudinal axis (3) tubular envelopes (42), device for contactless purification of tubular membranes (42), including at least one decontaminating ring (1), embracing tubular envelope (42), and at least one drive (35, 46) of decontamination ring (1) travel towards axis (3). Purifying ring (1) is located at a distance (d) from tubular envelope (42) surface. Holes (6), directed towards tubular envelope (42), and means for supply of liquid into said holes (6) under high pressure are made in purifying ring (1).EFFECT: invention makes it possible to purify surfaces of tubular envelopes by contactless method.11 cl, 5 dwg |
