Electrochemical Removal of Microorganisms in Drinking Water
Abstract:
It is known that silver, even in small concentrations (hundred parts of
milligrams per liter), has the ability to destroy microorganisms, i.e.
it has strong bactericidal abilities. Cleansing vast amount of water
using bactericidal ability of silver is usually performed in
electrochemical way. The advantages of electrochemical disinfection
process like: (a) environmental compatibility, (b) versatility to kill a
wide variety of microorganisms under mild conditions, (c) no need for
adding chemical medicines and (d) the benefits of in-situ generation
greatly lower problems and dangers of usage gas chlorine in water
disinfection, which is greatest during transport and storing of this
disinfectant. Appliances for electrochemical disinfection of drinking
water eliminate these faults of conventional disinfection methods.
Medical researches show that excess of chlorine in water reacts with
organic matter, leading to mutations and cancer formation in digestion
organs and bladder. This paper represents research of succesful
microbiological disinfection of natural water that contains
Acinetobacter, Pseudomonas aeruginisa, Sulfate-reducing clostridium,
Streptococcus (F), Aeromonas, Citrobacter (F), Esherichia coli,
Enterobacter (F) and Bacillus by water-disinfection appliance. This
appliance can be used in water systems like water sorces, traps,
reservoires, pools etc. (certificate of Clinical Center of Serbia).
