Excerpt from Sewage and the Bacterial: Purification of Sewage
The rapid development in modern ideas of sewage purification by bacterial processes necessitates a careful review of the methods of disposal at present sanctioned. The important reports published by the London County Council, Manchester, Leeds, and other towns in this country, as well as those of commissions appointed by sanitary authorities in the United States and on the Continent, and the frequent discussions and papers in the technical press, lead me to the view that a resume would be acceptable to a wide class of readers in this country.
The Royal Commission at present engaged on this subject will, no doubt, carefully weigh the evidence which is being placed before it, and we may confidently expect that its conclusions will be in accord with those obtained from the experiments which have now been carried out on sufficiently large a scale to establish the safety of embarking on the treatment of sewage on bacterial lines for even the largest centres of population.
The theoretical basis of the bacterial changes, so far as they have been at present studied, must underlie all the practical schemes which may in the future be put forward, and it has been my endeavour in the following pages to deal with the subject from this point of view.
I have to thank many friends and firms for information and the loan of blocks, and also my assistant, Mr. C. G. Stewart, for helping me in preparing the work for the press.
