A Practical Manual On Sea Water Distillation
With A Description Of The Necessary Machinery For The Process

6 SEA WATER DISTILLATION. rial purposes (when filtration and absence of aeration are not only unnecessary but indeed objectionable), such as the feeding of water-tu be boilers, the manufacture of mineral waters—i.e., in connection with mineral water making machinery, making ice, and in connection with accumulators and storage batteries at electrical gener- ating stations, laundries, &c. These are the principal uses for distilled water. 13. The distilled water is made, not only from sea water, but also from any water that has saline matter dissolved in quantities that make the quality of such water objectionable for the use it is required. General Object of this Book. 14. The object of this work, being intended to give some practical information regarding the distillation of sea water and impure water, it is now proposed to de- scribe in detail the various parts of a distilling apparatus, first as ordinarily in use in steam ships—that is, not only in H.M. service, but on liners and yachts—and then to describe the types of distilling machinery mostly used on land, where the conditions of working are somewhat different from those prevailing on steam ships.
