At the right, on this page, there is an interesting view, whichpresents a sectional diagramatic view of one of the Kennicottsofteners to illustrate the method of operation. The construc-tion shown in this view is that used in the smaller softeners ofthe installation on the Pittsburg & Lake Erie, although it doesnot differ in principle from the large softener at McKees arrangement of the baffle plates outside of the settling coneand of the lime-saturator tank within, as well as the other im-. SECTIONAL VIEW OF A TYPICAL KENNICOTT WATERSOFTENER, SHOWING CLEARLY ITS INTERNALCONSTRUCTION. 1 10 hours per day Iwith the presentmodeof treatment,1,974 lbs. of solidmatter are precip-itated. Water is supplied to this softener from a well 45 ft. deep bytwo direct-connected motor-driven centrifugal pumps, whichare operated at speeds of from 840 to 1,200 rev. per min. Eachpump has a capacity of 1,000 gals, per min., one pump onlybeing worked at one time. They lift the water about 85 ft. ata cost Of about (6-10 cent) per 1,000 gals.—for powerand labor. At the present time the amount of scale-formingimpurities in the water is reduced from the raw water condi-tion of about 24 grains per gallon to less than 5 grains per gal-lon after treatment.
