PENGGUNAAN KUAT ARUS LISTRIK DALAM PROSES STERILISASI AIR

Drinking water is water which through the treatment process or without any processing that appropriate health requirements. To complete drinking water needed, people also consume drinking water from water refill outlet. However, water refill outlet in Indonesia ever known produced bad quality of drinking water because there were Escherichia coli bacteria, which indicates that the drinking water is contaminated with pathogens that can cause gastrointestinal complaints such as diarrhea. The water filter that use in water refill outlet is less effective in killing Escherichia coli bacteria. To improve the filter performance, it required an electrical currents intensity exposure that can reduce the amount of bacteria in drinking water refill.
This research was conducted by using Total Plate Count (TPC) to determine the amount of bacteria in the water refill exposed and not exposed to electrical current intensity 3 ampere for 2 hours. Both samples were planted on EMB media for 24 hours at 37 ° C.
The results obtained for samples which is not exposed electrical currents intensity obtained in 1032 colony of Escherichia coli and which is exposed electrical current intensity can not be found colonies of bacteria with a sample volume of 10 ml. This suggests that electrical current intensity can inhibit the growth of Escherichia coli only at a certain volume.
