Abstract
THE subject of industrial water supply and stream pollution was discussed at the joint meeting of the Institution of Chemical Engineers and the American Institute of Chemical Engineers, which was held on July 17, in Leeds. Messrs. F. P. Veitch and L. C. Benedict, of the Bureau of Chemistry (U.S.A.), contributed a valuable paper on the composition and disposal of wool-scouring waste liquors, in which they described current methods of recovering wool-grease and fertilising material from them, as well as recent work done by the Bureau which indicates the superior advantages of extracting with naphtha and subsequent scouring with soap and water. They estimate that the wool-scouring liquors annually produced in the United States contain, in millions of pounds weight, grease 60-70, potash salts 40-48, nitrogenous matter 15, and dirt 60-90, the total value of which is about 5 million dollars. The authors are convinced that wholesale economic recovery of the valuable ingredients is possible.
