Electricity to Purify Sewage.
“The sanitary condition of your city certainly demands attention,” said a traveling man in the Booge corridors last evening. “I understand diphtheria is almost epidemic in your city and this condition must in a large degree be due to decaying vegetable matter contaminating the atmosphere. From the sewers come poisonous germs of many kinds and right here is a great problem. Some years ago a scheme was advanced for the solution of the great sanitary problem by employing electricity for the purification of sewage. The process was exceedingly simple, but financial difficulties stood in the way of its being carried out. Electrodes were put into liquefied sewage and large quantities of oxygen generated ; the oxidizablc matter was thus brought into contact with the ozone and disinfection was effected in a very short time. Recently the question of applying this system to the waste product of factories, which are now allowed to contaminate the waters of a city was agitated, and now a medical scientist, I do not remember his name, proposes that it be employed for disinfecting the sewage of hospitals and such institutions in cities and towns where the public health demands that greater care be adopted in the prevention of the spread of infectious diseases.”
