Book excerpt: 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.
