The problem of sewage disposal. Composition and character of 1–13 sewage. Action of bacteria. Soils and their value for sewage treatment. Three essential conditions for effective sewage purification. Rates of operation. Preliminary and final treatment.
In order to estimate the cost of installing a sewage-disposal plant and of treating continuously the sewage from any residence, certain fundamental assumptions are always necess...
12. CHAPTER VIt has been shown that the selection of the type of plant best suited to solve the sewage-disposal problem at any given place depends on several factors and can be safely made o...
9. CHAPTER IIAs has been stated, a most effective preliminary step in the treatment of sewage is to pass it through a properly designed settling tank in order that the grosser solids and sus...
11. CHAPTER IVThe disposal of sewage by the method of sub-surface irrigation, sometimes known as the Waring system, consists in its distribution by means of open jointed tiling over a compara...
8. CHAPTER IThe problem of sewage disposal for a single house differs from the corresponding problem for a city chiefly in two ways: first, because in the city it is becoming, if it has not...
13. CHAPTER VIFor many years it has seemed to thoughtful persons that permitting sewage, either from single houses or from larger communities, to be turned into streams was a mistaken policy...
10. CHAPTER IIIIt was explained in Chapter I that one of the essentials of successful sewage purification is an intermittent application of the sewage to the beds in which bacteria are to act....
