There is a float in the hard-water boxwhich varies at the rate of How of the soda and lime solutions, ac-cording to the head and rate of flow from the box to the softening-tank. In order to provide soft water for making the lime watersolution, the scoop wheel seen revolves continuously, emptyingenough purified water into anadjacent box to supply thelime-water saturator. Thehme saturator is the cylinderin the middle of the appa-ratus. The soft water fromI he box supplied from tin.
