Excerpt from Conference of Municipal and Private Owned Water Plants of Indiana With the State Board of Health at Indianapolis, July 8 and 9, 1908There is another word which may be said here, and this is more of a foreword than otherwise, and that is in regard to those dis solved inorganic matters, the salts in solution which give water its hardness. It seems to me that this matter is one which is certain to receive much more attention in the future than it has in the past. It is well known that hard waters are not well adapted to boiler uses, the salts being deposited upon the heating surfaces in the form of scale, rendering frequent cleaning necessary, and im pairing to a certain extent the efficiency of the boiler as a steam generator. It is also well known that hard water is not so satis factory for domestic use as soft water, the hard water requiring much more soap to make it effective in cleaning work, but if the necessary expenditure for soap in any given city as between hard and soft water were tabluated, it is probable that both the sum total in each case and also the difference would be surprising.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
