Excerpt from Sewage Works Analyses

Through the courtesy of Mr. F. Scudder, the author has also been able to include descriptions of some of the more important processes employed in the laboratory of the Mersey and Irwell Joint Committee.
In general, it may be said that the Joint Committee"s methods are designed for cases where samples from different works have to be critically examined, the Manchester methods for the analysis of a large number of samples of sewage and effluents of the same general character.
The successful application of modern bacterial processes will necessitate careful chemical control.
