This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 edition. Excerpt: ...with typical installations with which the author is familiar, or respecting which authentic information is available. The English plants considered are those at Manchester, Salford, Worcester, and Stamford, while the following American plants are mentioned: Milwaukee, Houston, and the 1ll. State Water Survey. A summary of the progress of the method is given, together with intimations of what may be expected in the future. 297 The activated sludge process. S. Barwise. Surveyor 52, 40. Describes the principles involved in this method of sewage treatment, and speculates as to the various methods of applying these in the future; for example, in the form of a new percolating filter. 298 Activated sludge treatment at Worcester. (Eng.) Editorial. Surveyor 52, 45-6. Remarks on the paper of Mr. T. Caink (Ref.

Caink describes the incident of large quantities of tarry matter entering the tanks, and interfering seriously with the purification. The O absorption in the sewage rose from 30 or 40 p. p. m. to 140, and in the effluent from 8 p. p. m. to 84. The latter contained only 28 p. p. m. of suspended matter, however, and was stable for 5 days. Antiseptics of this or any other kind should be kept from the sewers, as they operate injuriously against any system of bacterial purification. Mr. W. H. Duckworth said that personally he believed there was a great future for the activated sludge process from several points of view, and agreed with Mr. Caink...
