Aeration of Water.
An important experiment in water- purification has recently been carried out at Philadelphia, under the superintendence of tha chief engineer to the water-supply department of that city. It ha 3 been known for some time that the purifying action of air upon water is much increased if the two be mingled under pressure, but the fact existed simply as the result of a laboratory experiment. To try the practicability of the principle on a bi# scale, a large turbine waa converted into an air-pump, and was made to deliver a measured voiume of air to a water-main. On analysis of the water before and afti'r the experiment, it was found that the quantity of free oxygen in the water had increased by seventeen per cent. The amount of oxygen indioftted represents the excess of whti* was required to purify the organic mattei combined in the water previous to its itcn.tio.ri. Th« lediiU of the experiment ia considered highly safe factory.
