(2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series The principal intention of this series is to help readers formulate answers to the last two questions above The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution control.” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken Prerequisite to such planning is an understanding of the performance, potential, and limitations of the various methods of pollution abatement available for environmental scientists and engineers In this series of handbooks, we will review at a tutorial level a broad spectrum of engineering systems (processes, operations, and methods) currently being utilized, or of potential utility, for pollution abatement We believe that the unified interdisciplinary approach presented in these handbooks is a logical step in the evolution of environmental engineering Treatment of the various engineering systems presented will show how an engineering formulation of the subject flows naturally from the fundamental principles and theories of chemistry, microbiology, physics, and mathematics This emphasis on fundamental science recognizes that engineering practice has in recent years become more firmly based on scientific principles rather than on its earlier dependency on empirical accumulation of facts It is not intended, though, to neglect empiricism where such data lead quickly to the most economic design; certain engineering systems are not readily amenable to fundamental scientific analysis, and in these instances we have resorted to less science in favor of more art and empiricism Since an environmental engineer must understand science within the context of application, we first present the development of the scientific basis of a particular subject, followed by exposition of the pertinent design concepts and v vi Preface operations, and detailed explanations of their applications to environmental quality control or remediation Throughout the series, methods of practical design and calculation are illustrated by numerical examples These examples clearly demonstrate how organized, analytical reasoning leads to the most direct and clear solutions Wherever possible, pertinent cost data have been provided Our treatment of pollution-abatement engineering is offered in the belief that the trained engineer should more firmly understand fundamental principles, be more aware of the similarities and/or differences among many of the engineering systems, and exhibit greater flexibility and originality in the definition and innovative solution of environmental pollution problems In short, the environmental engineer should by conviction and practice be more readily adaptable to change and progress Coverage of the unusually broad field of environmental engineering has demanded an expertise that could only be provided through multiple authorships Each author (or group of authors) was permitted to employ, within reasonable limits, the customary personal style in organizing and presenting a particular subject area; consequently, it has been difficult to treat all subject material in a homogeneous manner Moreover, owing to limitations of space, some of the authors’ favored topics could not be treated in great detail, and many less important topics had to be merely mentioned or commented on briefly All authors have provided an excellent list of references at the end of each chapter for the benefit of interested readers As each chapter is meant to be self-contained, some mild repetition among the various texts was unavoidable In each case, all omissions or repetitions are the responsibility of the editors and not the individual authors With the current trend toward metrication, the question of using a consistent system of units has been a problem Wherever possible, the authors have used the British system (fps) along with the metric equivalent (mks, cgs, or SIU) or vice versa The editors sincerely hope that this duplicity of units’ usage will prove to be useful rather than being disruptive to the readers The goals of the Handbook of Environmental Engineering series are: (1) to cover entire environmental fields, including air and noise pollution control, solid waste processing and resource recovery, physicochemical treatment processes, biological treatment processes, biosolids management, water resources, natural control processes, radioactive waste disposal and thermal pollution control; and (2) to employ a multimedia approach to environmental pollution control since air, water, soil and energy are all interrelated As can be seen from the above handbook coverage, the organization of the handbook series has been based on the three basic forms in which pollutants and waste are manifested: gas, solid, and liquid In addition, noise pollution control is included in the handbook series This particular book Volume Advanced Physicochemical Treatment Technologies is a sister book to Volume Physicochemical Treatment Processes and Volume Advanced Physicochemical Treatment Processes Volumes and have already included the subjects of screening, comminution, equalization, neu- Preface vii tralization, mixing, coagulation, flocculation, chemical precipitation, recarbonation, softening, oxidation, halogenation, chlorination, disinfection, ozonation, electrolysis, sedimentation, dissolved air flotation, filtration, polymeric adsorption, granular activated carbon adsorption, membrane processes, sludge treatment processes, potable water aeration, air stripping, dispersed air flotation, powdered activated carbon adsorption, diatomaceous earth precoat filtration, microscreening, membrane filtration, ion exchange, fluoridation, defluoridation, ultraviolet radiation disinfection, chloramination, dechlorination, advanced oxidation processes, chemical reduction/oxidation, oil water separation, evaporation and solvent extraction This book, Volume 5, includes the subjects of pressurized ozonation, electrochemical processes, irradiation, nonthermal plasma, thermal distillation, electrodialysis, reverse osmosis, biosorption, emerging adsorption, emerging ion exchange, emerging flotation, fine pore aeration, endocrine disruptors, small filtration systems, chemical feeding systems, wet air oxidation, and lime calcination All three books have been designed to serve as comprehensive physicochemical treatment textbooks as well as wide-ranging reference books We hope and expect that the books will prove of equal high value to advanced undergraduate and graduate students, to designers of water and wastewater treatment systems, and to scientists and researchers The editors welcome comments from readers in all of these categories The editors are pleased to acknowledge the encouragement and support received from their colleagues and the publisher during the conceptual stages of this endeavor We wish to thank the contributing authors for their time and effort, and for having patiently borne our reviews and numerous queries and comments We are very grateful to our respective families for their patience and understanding during some rather trying times Lawrence K Wang, Lenox, MA Yung-Tse Hung, Cleveland, OH Nazih K Shammas, Lenox, MA Contents Preface v Contributors xvii Pressurized Ozonation Lawrence K Wang and Nazih K Shammas 1 Introduction
