Abstract

The aim of this study is to determine the effect of Silver and electrical current in preventing the growth of bacteria in drinking water to keep water safe. Silver in the form of thin discs was immersed in drinking water samples at various intervals; 2, 4 and 8 days at room temperature (20 ±2 o C). The total number of bacteria isolates in water samples were significantly reduced with time. Furthermore, no bacteria were isolated when we used electrical current with silver, however,  the result of Plasma atomic emission spectrometer(PAES) analysis showed that the concentration of Ag+  ions which may be released with treatment is between 0.001- 0.0001 µg/ml. Thus, the treatment of drinking water with silver discs is confirmed to be effective in realizing both its antibacterial and bioactive properties.
