Silver and its Salts for the Disinfection and
the Preservation of Water for Potable use

ARGOX WLTM
Already at beginning of the century the bactericide and bacteriostatic properties of the silver and its hydrosoluble salts have been applied to the waters treatment for human consumption. For this purpose have been employed solutions of silver salts and colloidal silver, whose bactericide action has been verified in particular on pathogenic germs (Salmonella) and on indicator germs of fecal pollution (Coli). Afterwards the silver has been added to the water exclusively by an electrolytical process (Electro-Katadyn system); however the ionic silver action is the same for all treatment methods. The ionic silver doesn’t modify neither the aspect, the colour, the odour, the taste of the water and the products prepared with it (reconstituted milk, ORS solution for the oral rehydration), nor forms toxic or critical compounds with components and impurities of the water, on the contrary for the chlorine. To the normal dosing concentration for the waters (CH: 100 ppb, EC: 80 ppb) the silver doesn’t cause neither any toxic effect on the human organism, nor any cancerous or mutagenic action. Doesn’t exist any contraindication for the silver employment in the potable water treatments.
The ARGOX WLTM solution has been developed in especially for WSE (water supplying in emergency situations), in order to guarantee the long-lasting conservation of the potable water into reservoirs (civil protection refugee camps etc.) or into foodgrade sterile plastic bags, which permits the constitution of water storage and the same must substitute the individual supply with too much chlorinated water or derived from non-hygienical containers.
The ARGOX WLTM solution is directly added to the water coming from the distribution net or from treatment installations by the usual dosing pumps. The dosing system of the solution is especially more accurate than electrolytical one, which depends notoriously from the electrodes state and from the amperage performance. The potable water added with ionic silver and packed into plastic bags or contained into reservoirs is a water suitable to the long-lasting conservation. It is advisable that the storage of the bags is taking place in a cool environment and protected from the direct sunlight; in such conditions the water can constitute stock to renew every 5 years.

Available as a concentrate in 5 Liter plastic-containers containing 10 g of silver. With one container 100’000 liters of potable water can be preserved.
