Industrial Waste Treatment
Serious treatment of industrial wastes did not really begin in the United States until the 1930s, and then only in a few industries with easy and obvious remedies, such as screening feathers from poultry processing effluents and even the lagooning of certain papermill wastes. The extent of treatment grew during the next 70 years of the twentieth century. It broadened during this period to include many types of industries. The complexity of treatment also increased as environmental restrictions became greater. Growth was enhanced also by progress in industrial waste treatment research findings. rnThe goal of effective industrial waste treatment is directed towards the removal of all contaminants that adversely impact the water as well as air and land environments. One should keep this goal in mind at all times regardless of the presence or absence of governmental or economic constraints.rnWaste treatment findings and practices are presented largely in Part A of this book. Many of these carry over into the twenty first century. In fact, one can discover twentieth century industries that were practicing the twenty first century advanced treatment methods. Treatment decisions have always been affected by regulatory and economic constraints regardless of scientific knowledge. And they probably always will until we are able to include the cost of these constraints in industrial production decisions.rnTwenty first century thinking, if not actual practice, is presented in Part B. Keeping in mind that many older techniques are still being carried over into this century. In addition, as expected, the twenty first century environmental engineer is benefiting from the massive industrial waste research and treatments utilized during the twentieth century. The reader realizes that resources of our receiving environments (air, water, and land) are finite. And as such these resources must be protected with greater intensity and utilized much more economically than previously. rnKey features:rn• Provides a working plan for implementing new industrial complexes that incorporate the solutions to product waste generation from the very onset of product design to its final disposal.rn• Offers the reader a multitude of actual and potential systems of environmentally balanced industrial complexes necessary to deal practically, fully and economically with our present industrial waste dilemma.rn• Detailed explanation of how to facilitate long term, comprehensive, cost effective solutions that avoid such mistakes of the past such as love canal.rnWritten by a world leading environmental engineer, Nemerow illustrates in detail the efforts of the 20th century environmentalists to solve the industrial waste problems in order to protect us against environmentally dangerous situations. Industrial waste treatment focuses on why treatment techniques eventually are not entirely satisfactory and effective in ameliorating the pollution existing in our environment. As a consequence, the 21st century environmentalists are resorting to a new system of direct reuse of waste by adjacent industries in order to avoid waste treatment costs and at the same time produce new products at lower costs. Nemerow presents historical justification leading up to the new, 21st century thinking and action. rnNelson L. Nemerow has published over 210 technical papers and 23 textbooks on industrial waste treatment and steam pollution. Nemerow retired from teaching, after serving 50 years as an environmental engineering professor. Before retiring, he worked as a consultant in the and was the advisor to the United Nations Industrial Development Organization in Vienna and the World Health Organization.rn
