Water Purification Classic Reprint

Excerpt from Water Purification In the following pages it is intended to treat only of the first division of this subject, since the second covers too broad a field to bring it Within the mom of this volume. Both the kind and the amount of impurities in a polluted water affect the methods which can be employed for its purification, and this is so peculiarly true of sewage that its treatment has become an art in itself. Those waters which are to be purified for drinking purposes demand that a degree Of purity shall be produced which is not possible and usually unnecessary in the case Of sewage. The purification of the latter is, as a rule, quite incomplete as compared with that required for a safe drinking water, and obviously the Object to be attained is quite difl'erent. In the case of waters to be treated for making them suitable for steam-boiler purposes, or for general industrial uses, a slightly different Object is sought. The softening of hard waters or the removal of compounds of iron or manganese may be an integral part of the purification of a public drinking water supply, in which case it is combined with those processes utilized for making a water hygienically safe. Of course it is quite possible to carry on purification for industrial purposes independently of the more refined methods used for drinking water, and frequently this course is pursued in connection with manufacturing plants.

Excerpt from The Filtration of Public Water-Supplies There are three principal methods of securing a good water supply for a large city. The first consists of damming a stream from an uninhabited or but sparsely inhabited watershed, thus forming an impounding reservoir. This method is extensively used in England and in the United States. In the latter most of the really good and large Supplies are so obtained. It is only applicable to places having suitable watersheds within a reason. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Water Purification Plants and Their Operation: Second Edition With these ends in view Chapter IV and parts of Chapter V have been entirely rewritten. It is difficult to adequately; cover the interpretation of tests in a limited space and in such a manner as to be available for non-technical men. The treat meflt may seem somewhat arbitrary, but it is believed that care ful reading of the articles on interpretation Will convince the trained bacteriologist that they are basically sound and err on the side of safety.

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.

The saving involved if these two decisions could be successfully carried out was of a very material kind.
