Excerpt from The Surveyor and Municipal and County Engineer, Vol. 50: July 7 to December 29, 1916 As a flow of 25000 gallons per hour is necessary to keep the turbines working, it was thought advisable to install an arrangement. Whereby alumina could be added to the raw water on the Venturi principle described in the case of lime water. Governors driven by the turbine shafts were made to operate a tap controlling a subsidiary alumina solution supply. Whenever the turbines slowed down sufficiently for the balls to - loose their spread the tap was automatic al'y opened and rice L'eraa. Night consumption has ince increased sufficiently to render this arrangement unnecessary. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
