Excerpt from Water Purification and Sewage Disposal Since the recognition of their significance in the promotion of the public health, methods of water purification and sewage disposal have earned a steadily increasing importance. Consequently, these branches of industry have enjoyed the most zealous atten tion of the scientist and of the engineer. I have endeavoured in the present monograph to give a survey, short perhaps, but as complete as possible, of the present position in regard to Water Purification and Sewage Disposal. Owing to the wide range of this subject particular processes could only be treated shortly in the space at disposal. One chapter, which is very fully treated in the present volume, though slightly elsewhere, is the disposal of industrial sewage. Many of the processes of purification are of quite recent date, and fresh experience is being obtained daily and reported upon in the most diverse publications. I have endeavoured to collect such information. In the translation some small changes and additions have been made in the chapters on sand filtration, the removal of manganese, and Travis and Emscher wells.

Excerpt from Sewage Purification and Disposal By an avoidance of technical terms and the presenta tion of the text in a simple manner, it was hoped to make sewage purification and disposal valuable, not only in the class room and for engineers and architects, but like wise to engineering and architectural students, municipal officials, sewage disposal committees, and everybody else interested in the subject.

Excerpt from Sewage Disposal There appears to be no room for doubt but that the treatment of sewage on intermittent sand filters will, in the vast majority of instances, yield the highest degree of purification of all the known methods of sewage treatment. In England the natural soil is not uniformly favor able to this form of treatment, and except in the northern and eastern sections, the same is true in this country. It has become necessary, therefore, to pay particular attention to the perfection of numerous forms of preparatory treatment, whereby higher rates are made possible in the case of intermittent sand filtration, and other subsidiary processes, there by reducing the cost of the plant by reducing the acreage required. It has also become necessary to study more carefully the applicability of certain of the more recently devised methods of sewage treatment, where in coarse-grain material, Such as is locally available, can be made use of.

Excerpt from Sewage Treatment, Purification, and Utilization The importance of the Sewage question may, perhaps, be fairly gauged by the number of patents of which it has been the subject, and its still unsettled state may be concluded from their varied and contradictory character. Freezing and heating, concentration and dilution, electrisation and magnetising, the addition of oxidisers and deoxidisers, of ferments and preventives of fermentation recommended, if not actually tried, show the want of any distinct and generally recognised principle. I have, therefore, thought it my duty to lay before the public in plain language and in a concise form the result of my experience in treating sewage and waste waters. That experience dates back to the year 1868, and except in 1870 my attention has during the whole of that time been almost exclusively directed to this question. I have worked with sewage in every quantity, from a few ounces in a beaker or a hydrometer-jar to a daily flow of ten million gallons. I have had opportunities for examining almost every known process, irrigation, filtration, aeration as well as precipitation in its many variations.

Excerpt from Sewerage and Sewage Disposal Having had occasion in my own practice to in vestigate the information which of recent years has become available to engineers, through the researches of chemists and biologists, in relation to Water Supply, Sewerage and Sewage Disposal, I have thought that a concise summary of the most important data would be useful. I have confined this book as far as possible within the limits of data in connection with works of Sewerage and Sewage Disposal, although in dealing with River Pollution and Filtration of Impure Water, the allied subjects of Water Pollution and Sewage Purification necessarily overlap. In fact, the functions of micro-organisms, which affect the consideration of both, must be well understood by engineers who have to advise in.

Excerpt from The Design, Construction and Maintenance of Sewage Disposal Works: Being a Practical Guide to Modern Methods of Sewage Purification Sewage disposal works comprise all the artificial means employed for facilitating the purification of sewage; and although such Works may be designed for the applica tion of many different mechanical, chemical, and biological processes, the ultimate aim and object of them all is to separate the organic matters contained in the sewage from the water in which they are dissolved or suspended, and to render them innocuous by decomposition and oxidation, while at the same time restoring the water itself to a state of Comparative purity, so that. It may not injuriously affect any stream, river, or tidal estuary through which it may pass on its way back to the sea.
