Practical application of "silver water"
The use of silver for the disinfection of water not only increases the arsenal of existing reagents, but is also one of the most effective methods of disinfection and canning of drinking water.
So, comparing the action of chlorine, a common disinfectant( and this is one of the worst poisons), with the action of silver, one can establish the following:
1) when interacting with organic substances and other impurities of water, both silver and chlorine are gradually inactivated,in contrast to chlorine, the activity of silver persists for a long time;
2) the introduction of chlorine into water, even in small amounts, worsens its taste and smell, irritates the mucous membranes, while silver, even at a relatively high concentration, does not change these water indices, and no irritating effect on the body occurs;
3) silver causes the death of vegetative forms of bacteria, delays the development of spores, inhibits the growth of blue-green algae, protozoa, fungi, etc.
Thus, silver, acting slower than chlorine and retaining bactericidal properties for a long time, can be successfully appliedin those cases when the use of chlorine is contraindicated. For example, on ships, in swimming pools, in the field, and so on, as well as in cases when chlorine, when interacting with impurities of water, gives toxic or strongly-smelling compounds. This method today
is applied in the USA, England, Switzerland, Germany, France, Czech Republic, Yugoslavia and other countries.
High bactericidal activity of electrolytic silver solution is recognized as highly effective
and is mainly used for canning of drinking water. This method will allow with a high degree of assurance to disinfect and preserve water on sea vessels for the whole time of flights. Today, such water is used by astronauts.
Silver in a dose of 0.2 mg / l was an excellent preservative of mineral water and soft drinks.
Silver behaves perfectly when preserving citrus and vegetable, fruit juices( 0.5 mg / l).Duration of storage increases from 7 days to a year. The use of electrolytic silver for the sterilization of grape and fruit juices requires fresh, clarified and filtered to juice juice. Then, 5-7.5 or 7.5-10 mg / l of silver is injected and the sterile bottles are placed in a thermostat for 10-120 days at a temperature of 30-32?C.
Application of silver ions leads to acceleration of aging processes of wines, improvement of their taste qualities and aroma.
Anodized silver perfectly disinfects dishes, cups, spoons, plates intended for general use, while conventional washing does not ensure complete destruction of microflora.
It is proved that silver does not destroy the vitamin C contained in milk and makes it possible to extend the shelf life of canned milk in winter to 4-5 days, in summer - up to a day.
A dose of silver of 6-8 mg / l, added to milk shortly after milking, stabilizes this product.
The concentration of silver 2,2-3,75 mg / l in water, used in the production of butter, leads to an increase in its preservation, taste. When immersing chicken eggs in electrolytic silver solutions for 1-2 hours at a concentration of 20 mg / l, very effective disinfection of the shell is achieved. Addition of "silver water" to the egg mass( 10 mg of silver per 2 liters of egg mass) leads to a significant decrease in bacteria in the production of melange and egg powder.
Electrolysis directly in milk( 5-6 mg / l) increases the shelf life for 2-3 days without changing the taste.
All brewing bacteria and mold fungi die in a very short time when water is treated with a 0.5-0.6 mg / l dose of silver. The most stable was beer sarcin, but it also perishes for an hour at a dose of 0.5 mg / l.
"Silver Water" is an excellent disinfectant of pipelines in beer plants. Acetic acid bacteria perish at silver doses of 0.025-0.05 mg / l with a contact time of 30 minutes.
Use "silver water" to fight the molding of meat in cold stores in a meat-packing plant.
Solutions of silver salts are used to stabilize and conserve blood used in the food industry.
Silver in a concentration of at least 10 mg / l disinfects gelatin during cooking. Electrolytic solution can be used to store some potions, infusions, eye and ear, for canning the prepared organs. The presence of silver in a dose of 4.0 mg / l stabilizes perishable infusions( for 5 or more days) for a long time.
Antimicrobial properties of silver are used to protect aviation fuel from microorganisms.
