DIVISION I.—CHEMICAL AND GENERAL.
I.—Introductory Summary.
II.—Experimental Bacterial Treatment of Crude Sewage at the Northern
Outfall Works (Barking).
1. Primary and Secondary Treatment in beds of Kentish Ragstone and
Coke, 5 feet in depth.
2. Primary and Secondary Treatment in beds of Coke, 10 feet in depth.
3. The Bacterial Treatment of the Sedimented Chemical Effluent in the
one-acre Coke-bed, 6 feet in depth.
III.—Further Experiments on Crude Sewage—Bacterial Treatment at the
Southern Outfall (Crossness).
1. Intermittent Treatment of Crude Sewage by single contact in a Coke-
bed, 13 feet in depth.
2. Experiment on the Bacterial Treatment of Rapidly Sedimented Crude
Sewage.
3. Appended Report on the 13-foot Coke-bed. Feeding with Sedimented
Sewage, and increased number of fillings per twenty-four hours.
January 20th to July 28th, 1900.
4. Liquid capacity of a Coke-bed, as it is affected by the size of the Coke
fragments.
IV.—Tabulation of the Results of the Chemical Examination of the
Bacterially-treated Crude Sewage and Effluents.
1. Barking results.
2. Crossness results.
