The device comprises: a UV meter (32) is connected to the chamber with ramp, in percentage compared to the intensity of the lamps emitted at the beginning of their lives; automatic cleaning device (34) is connected to the chamber with ramp by scraping to eliminate the deposits formed on the quartz sheaths surrounding the lamps; a three-way electrovalve (22) placed between the source (10) and the filter and another electrovalve (26) placed between the pump and the ramp (14, 20). The pump (12) is fitted to supply under high-pressure 45-110 bars. The filter (16 or 50, 52) retaining the particles having a dimension higher than 1 mu or a charged filter retaining the particles and colloidal substances having a dimension higher than 0.5 mu . The ultrafiltration filter (18) to retain the microorganisms having a dimension higher than 0.2 mu . The microorganisms of chamber having dimension is lower than 0.2 mu . The electrovalve placed in two positions, in which normal operation of the device and the circulation of the liquid supplied under pressure by the circuit pump, which is closed within the interiors to carry out the decontamination of the device by thermal shock. A reservoir with a float device (40) to maintain the maximum level of water, in which there is a heat resistant element to achieve a decontamination by thermal shock of the device at 70[deg]C for 10 minutes, when the pump was operated to circulation of water under a pressure of 5 bars. A proportioning pump supplying biocide or virucide products to prevent the formation of a biofilm in the pipes between the pump and the ramp and retaining the particles of size higher than 5 mu . Draining outlets for the ramp and pump. The pipes (11, 24, 28, 30) are connecting the copper element.
