A.1.1 Manufacture Silver chloride is made by precipitating silver ions with chloride ions in aqueous solution, usually by reaction of silver nitrate solution (well soluble silver salt) with alkali chloride solutions or hydrochloric acid The sparingly soluble silver chloride precipitate is washed with water, filtered off and dried." A.1.2 Effect The silver ion is the effective component of the compounds in the preservation of drinking water These silver ions are electrically charged particles of silver on the scale of atoms They penetrate the cell wall of the bacteria and cause a blockage of the enzyme system by inhibiting vital conversions into micro-organisms Thiol and carboxyl groups in particular form comparatively stable compounds with the silver ions The bacterial cells are not (or only partly) destroyed by silver ions Depending on the ambient conditions, they are reactivated after a time (one month to six months) and can then proliferate Through the addition of silver ions, drinking water can be protected against re-growth for up to six months, depending on ambient factors and the substances in the water The basic precondition for the use of the compounds referred to is a water quality compliant with !EU Directive 98/83/EC [2]", a clean container and a reaction time of at least h Organic water ingredients (TOC) and chlorides can reduce the effect of the silver salts As the temperature rises, the !microbiocidal" effect becomes stronger in step with the increase in ionisation A.1.3 Application The products described can be used for the preservation of water for human consumption in intermittent application in water supply plants, including their pipeline networks, with a maximum annual outflow of 000 m³ (small-size plants) It is the same for the preservation of water for the preparation of foodstuffs, water which is kept in enclosed systems (e.g water supply systems in land-, water- and airborne vehicles) or, in exceptional cases, water which is stored for emergencies The term “intermittent use” in the context of this European Standard means the non-systematic use, and the use on demand of silver salts respectively for the preservation of water (drinking water): — in case of interruption of operation in small-size plants for a prolonged period of time or if, as a result of low consumption and lengthy storage periods it can be assumed that the water supplied for human consumption will not meet the microbiological requirements of drinking water; — in food processing plants the preservation of drinking water as required - water which needs to be protected against possible re-growth on account of its intended use; — in mobile systems in land, water and airborne vehicles which pick up drinking water at different locations as opposed to the permanent or systematic use in a public drinking water supply (large plants with fixed pipeline networks and continuous feed) 16 BS EN 15030:2012+A1:2015 EN 15030:2012+A1:2015 (E) The term “exceptional case” means, in the context of this European Standard, the use of silver salts for the preservation of water for emergencies e.g packed drinking water A.2 Use A.2.1 Form in which it is used a) The products described are not used in pure substance form b) They are mixed with sodium chloride and are available in the form of tablets, powder or an aqueous solution referred to generally as "silver chloro complex" ! c) Silver chloride is used as such or mixed with solid sodium chloride (in the form of tablets or powder) or dissolved in an aqueous solution of sodium chloride (NaCl) to improve the speed of dissolution since pure silver chloride is only slowly dissolving in water." !Sodium chloride used for preparing solutions of silver chloride should conform to EN 973 [4]." A.2.2 Treatment dose !This refers to concentration of the active silver ions: the concentration of silver ions in the treated water adjusts to 0,05 mg/l to 0,10 mg/l due to the formation of sparingly soluble silver chloride or carbonate, irrespective of the basic concentrate of the added commercial product."
