Excerpt from Pure Air, Ozone and Water: A Practical Treatise of Their Utilisation, and Value in Oil, Grease, Soap, Paint, Glue and Other Industries As the necessity of the obtainment of a supply of pure air and water is essential to the life and growth of all organic matter, so in like manner is it important that those industries dealing with such substances should receive a similar treatment in the course of their manufacture into the various compounds for which they are employed. A practical treatise, therefore, of the purification of air and water, also the generation of ozone, and their utilisation in oil, grease, soap, paint and glue manufacture, and the benefits derivable therefrom, must necessarily prove of intrinsic value to those trades, likewise to other industries requiring similar commodities. The value of pure air for oxidation, purification, etc., is well known, but its practical utilisation by means of cheap methods have not until recent years been fully realised.
