Book Synopsis D 1252 - 58 T Tentative Method of Test for Chemical Oxygen Demand (Dichromate Oxygen Demand) of Industrial Waste Water by : Committee D-19
Download or read book D 1252 - 58 T Tentative Method of Test for Chemical Oxygen Demand (Dichromate Oxygen Demand) of Industrial Waste Water written by Committee D-19 and published by . This book was released on 1960 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: (A) This method describes a procedure for determining the quantity of oxygen which an industrial waste water will consume from a dichromate solution under specified conditions. (b) This method for chemical oxygen demand is recommended as a supplement to the biochemical oxygen demand (BOD) test, but not as a substitute for it (Note 1). Note 1.--In spite of weaknesses inherent in a biological assay, the biochemical oxygen demand (BOD) is the only test which indicates directly the quantity of oxygen that will be utilized by natural agencies in stabilizing or ganic matter. However, the test for chemical oxygen demand (COD) may be used in evaluating the treatment and control of industrial waste water, and may be correlated with the BOD. Since these tests, COD and BOD, are not uniformly effective in oxidizing organic chemical compounds, there is no inherent constant relationship between the results of these tests for all industrial waste waters. If the basic composition of an industrial waste water continues to be relatively uniform, a fairly constant correlation may be expected between these paramenters. (c) This method can be applied to individual concentrated industrial wastes and to the combined effluents from a chemical plant. Ferrous iron, nitrites, sulfites, sulfides, halides, etc., are oxidized as well as organic constituents. Chlorides are quantitatively oxidized by this method, with 1 ppm of chloride as Cl- exerting the equivalent of 0l226 ppm chemical oxygen demand. Therefore, small amounts of organic matter cannot be reliably determined in the presence of a high chloride content, such as would be found in sea water. Furthermore, low results may be obtained under certain conditions, since not all organic compounds are completely oxidized (see Section 10).

Book Synopsis Decentralised Sanitation and Reuse by : Piet Lens
Download or read book Decentralised Sanitation and Reuse written by Piet Lens and published by IWA Publishing. This book was released on 2001-03-01 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adopting a multi-disciplinary approach, Decentralised Sanitation and Reuse places public sanitation in a global context and provides a definitive discussion of current state-of-the-art sanitation technologies. It shows how these technologies can be implemented to integrate domestic waste and wastewater treatment in order to maximize resource recycling in domestic practice. Decentralised Sanitation and Reuse presents technical solutions for on-site collection and transport of concentrated waste streams, and focuses on the compromise between reliability and minimal water wastage. A whole range of available sustainable technologies, both low and high-tech, to treat concentrated (black water) and diluted (grey water) streams are addressed in detail from the fundamental scientific and engineering points of view. Sociological, economic and, particularly, environmental and public health aspects are essential issues within this book. The necessity of new infrastructure implementation and the resulting challenges for a good number of economic branches are illustrated with examples from architecture and town planning. Decentralised Sanitation and Reuse will be an invaluable resource for a wide academic and professional readership active in the fields of environmental protection and public sanitation.
