Show Hac terla by electricity the disease producing bacteria may be killed by a current of electricity as has been shown by experiments with bottles of water containing them by passing tho current from a battery through a loop of wire suspended in tha water it was found that a small voltage was sufficient to deprive the most active bacteria of life the consumption bacillus died under two and a quarter volts while other more hardy species could not survive more than three volts a half unfortunately this electrical method would be too expensive and troublesome for the householder to pursue it is suggested therefore that cities or water companies shall perform the entire task delivering the water to consumer in a condition guaranteed harmless according to the plan proposed the killing of the microbe is to be accomplished at tho reservoir nothing could be easier than to apply the energy of a battery by a current at one place in the supply pipes as to kill with absolute certainty every microbe that passed through in the water A dynamo with a capacity of 1000 volts would do the perfectly for the biggest possible p slaying all the bacteria going through and rendering innocuous all tho millions of gallons daily that a metropolis consumes all that is necessary is that a length of the pipe shall be biada of insulated material and through holes in its sides will be inserted wires representing the poles of the battery positive on one side and negative on the other set the dynamo going and the current springs through the water filling it with powerful electric waves necessarily fatal to all living organisms floating in the stream new york telegram |
