Biological Waste Treatment [antikvár]

PREFACE This book is the outgrowth of a course entitled "Bio-oxidation of Organic Wastes—Theory and Design" initiated at Manhattan College in 1955. The objective of the course was to present the fundamentáis of bio-oxidation which would serve as a framework for the analysis, design and opération of biological waste treatment facilities. This book reflects the authors' approach to the solution of waste treatment problems. It is not intended as a scientific treatise on the physics, chemistry and biology of waste treatment but rather as an engineering text applying principies of the aforementioned fields to the design and opération of waste treatment facilities. The authors have employed scientific principies which have been mathematically formulated and empirical relationships where necessary. Although this text is primarily intended to serve as a guide for the practising engineer, it should also serve as a useful reference for gradúate students in sanitary engineering. Due to the rapid expansion of the science and technology of waste treatment it is assumed that many of the concepts described in this book will be further developed and refined by the competent re-searchers from whose work the authors freely drew. The authors acknowledge the reproduction of many figures and tables taken from the publications: Sewage and Industrial Wastes; Water and Sewage Works ; Transactions of the American Society of Civil Engineers and Proceedings of the Purdue Industrial Waste Conférence. Reproductions from the manufacturers of waste treatment equipment are acknowledged in the text. A word of appréciation is due to the secretaries of the Civil Engineering Department, Berenice Maguire and Ruth Minihan, and to the many students who assisted in the préparation of this manuscript.
