Description
Summary:My special object in this paper is to direct attention to certain observations I have recently made bearing upon death of filters and grade of particles as affecting both the quality of the work done and the capital outlay involved. To effect the necessary changes it is essential that the sewage in a fine film shall be brought into intimate contact with the nitrifying organisms in the presence of an adequate supply of oxygen. It follows as they are maintained in a healthy active condition, the greater the amount and the better the quality of the work done. How then should a filter bed be constructed, so that, within a given cubic space, it shall afford the largest possible surface for bacterical growth under healthy conditions ? Clearly, I suggest, by reducing the particles composing the filter to the smallest size which is found to be compatible with free aeration.
