PWD - PuriWater Device - NO POWER, NO CHEMICALS, STOP LEGIONELLA Dear All, I would like to present the PWD System a PATENTED device (MADE IN ITALY); consists of a combination of mineral alloys which, in contact with water, exerts a chemical reaction of oxidation-reduction, and thus performs a triple action: Providing antibacterial action against E. coli, pseudomonas and Legionella, as well as limescale and chlorine The device is fully recyclable and offers a performance life of approximately 12 months. The PWD has many advantages and different fields of application, from the pools to the containers of drinking water. The operation of the device PWD, consists in a redox process with exchange of electrons where the external part-cathode (silver) gives up electrons to the inner part-anode (brass); this is oxidized while the external part (silver) is reduced. N.B. During the exchange the silver does not precipitate in the water, but rather goes to oxidize on the inside brass. DON’T REALEASE ANYTHING IN THE WATER The application fields of PWD can be summarized: - Water wells purification - Wastewater treatment - Swimming pools and ponds - Treatment of any type of container of water storage (tanks, water containers in campers, boats, etc.) - Dental surgeries, veterinary and livestock, aquariums, fish farms - Retail containers for extemporaneous jugs to use family - Treatment and prevention of Legionella infection to the water network of hospitals, hotels, campgrounds and pools This device is a low-cost solution in all the places where the water must be stored.
