Sewage Treatment Purification And Utilization PDF Download

Excerpt from Sewage Treatment, Purification, and Utilization The importance of the Sewage question may, perhaps, be fairly gauged by the number of patents of which it has been the subject, and its still unsettled state may be concluded from their varied and contradictory character. Freezing and heating, concentration and dilution, electrisation and magnetising, the addition of oxidisers and deoxidisers, of ferments and preventives of fermentation recommended, if not actually tried, show the want of any distinct and generally recognised principle. I have, therefore, thought it my duty to lay before the public in plain language and in a concise form the result of my experience in treating sewage and waste waters. That experience dates back to the year 1868, and except in 1870 my attention has during the whole of that time been almost exclusively directed to this question. I have worked with sewage in every quantity, from a few ounces in a beaker or a hydrometer-jar to a daily flow of ten million gallons. I have had opportunities for examining almost every known process, irrigation, filtration, aeration as well as precipitation in its many variations.
