Settleability Problems and Loss of Solids in the Activated Sludge Process (Paperback): Michael H Gerardi Settleability Problems and Loss of Solids in the Activated Sludge Process (Paperback)
Michael H Gerardi
R1,520 R1,080 Discovery Miles 10 800 Save R440 (29%) Shipped within 7 - 13 working days

Volume II of the definitive series on the microbiology of wastewater treatment

The activated sludge process is the most versatile, commonly used wastewater treatment system in North America; however, many activated sludge processes frequently experience operational problems related to poor compaction or settleability of secondary solids and loss of secondary solids from the clarifier. Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, Settleability Problems and Loss of Solids in the Activated Sludge Process speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency.

Michael H. Gerardi’s hands-on guide addresses the most common plant operational problems, such as increased costs, loss of treatment efficiency, and permit violations. Using numerous tables and illustrations, Settleability Problems provides microscopic and analytical techniques for troubleshooting and identifying the conditions responsible for settleability problems and loss of solids. It includes pictures of wet mounts and smears of acceptable and unacceptable microscopic conditions of the activated sludge and presents corrective measures for operational problems. Chapters include:

  • Undesired Filamentous Growth
  • Nutrient-Deficient Floc Particles
  • Denitrification
  • Slug Discharge of Soluble cBOD
  • Viscous Bulking or Zoogloeal Growth
  • Production and Accumulation of Foam and Scum

The Wastewater Microbiology Series tackles the critical topics of cost-effective operation, permit compliance, process control, and troubleshooting through a microbiological perspective. Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.

Stormwater - A Resource for Scientists, Engineers, and Policy Makers (Paperback): William G. Wilson Stormwater - A Resource for Scientists, Engineers, and Policy Makers (Paperback)
William G. Wilson
R688 R635 Discovery Miles 6 350 Save R53 (8%) Shipped within 7 - 12 working days

As cities grow and climates change, precipitation increases, and with every great storm-from record-breaking Boston blizzards to floods in Houston-come buckets of stormwater and a deluge of problems. In Stormwater, William G. Wilson brings us the first expansive guide to stormwater science and management in urban environments, where rising runoff threatens both human and environmental health. As Wilson shows, rivers of runoff flowing from manmade surfaces-such as roads, sidewalks, and industrial sites-carry a glut of sediments and pollutants. Unlike soil, pavement does not filter or biodegrade these contaminants. Oil, pesticides, road salts, metals, automobile chemicals, and bacteria all pour into stormwater systems. Often this runoff discharges directly into waterways, uncontrolled and untreated, damaging valuable ecosystems. Detailing the harm that can be caused by this urban runoff, Wilson also outlines methods of control, from restored watersheds to green roofs and rain gardens, and, in so doing, gives hope in the face of an omnipresent threat. Illustrated throughout, Stormwater will be an essential resource for urban planners and scientists, policy makers, citizen activists, and environmental educators in the stormy decades to come.

The only step-by-step guide to an exciting new chemical management and waste minimization methodology

Over the past decade, a revolutionary new approach to chemical supply has emerged that dramatically reduces chemical waste and chemical costs while improving company performance. Known as Shared Savings Chemical Management, it has already yielded astonishing results for several major North American manufacturing firms and numerous other companies. The first complete guide to this innovative chemical management methodology, Chemical Management acquaints you with Shared Savings principles and shows you how to put them to work in your company.

Thomas Bierma and Francis Waterstraat Jr. explore the environmental, health and safety, purchasing, inventory, tracking, waste disposal, and other major problems inherent to traditional chemical supply programs, and clearly explain how and why a Shared Savings Chemical Management program helps minimize or completely eliminate those problems. With the help of fascinating case studies, they demonstrate how Shared Savings techniques are currently being applied in five extremely successful plants belonging to GM, Ford, Chrysler, and Navistar International. What’s more, they provide you with a complete, step-by-step blueprint for designing and implementing a Shared Savings program tailored to your company.

Chemical Management is an indispensable resource for manufacturing managers, purchasing managers, environmental managers, health and safety managers, and others charged with developing more effective chemical waste minimization strategies for their companies.

A landfill is a site for the disposal of waste materials by burial. Historically, landfills have been the most common methods of organised waste disposal and remain so in many places around the world. Landfills may include internal waste disposal sites as well as sites used by many producers. Many landfills are also used for other waste management purposes, such as the temporary storage, consolidation and transfer, or processing of waste material (sorting, treatment, or recycling). A landfill also may refer to ground that has been filled in with soil and rocks instead of waste materials, so that it can be used for a specific purpose, such as for building houses. Unless they are stabilised, these areas may experience severe shaking or liquefaction of the ground in a large earthquake. This book presents new research in a field which is demanding and beginning to receive society's attention.

Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste generally exhibits one or more of these characteristics: ignitability, corrosivity, reactivity or toxicity. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. One major type is radioactive waste. This book brings together the latest research in this diverse field.

Sewage and Landfill Leachate - Assessment and Remediation of Environmental Hazards (Hardcover): Marco Ragazzi Sewage and Landfill Leachate - Assessment and Remediation of Environmental Hazards (Hardcover)
Marco Ragazzi
R2,234 Discovery Miles 22 340 Shipped within 7 - 12 working days

This title includes a number of Open Access chapters. This new book provides a multiperspective look at research into many elements of remediating environmental hazards connected to sewage and landfill leachate. Sewage and landfill leachate treatments include various processes that are used to manage and dispose of the liquid portions of solid waste. Untreated leachate and sewage are hazards to the environment if they enter the water system. The goal of treatment is to reduce the contaminating load to the point that leachate and sewage liquids may be safely released into groundwater, streams, lakes, and the ocean. Around the world, however, huge volumes of contaminated water from sewage and landfill leachate is still pumped directly into water systems, especially in the world's developing nations. Aside from the damage to marine environments and fisheries that this causes, it also jeopardizes the world's vulnerable water resources. This compendium volume explores effective sewage management, which is essential for nutrient recycling and for maintaining ecosystem integrity. It looks at a range of technologies that are available for the treatment of sewage and landfill leachate. The editor, himself a respected and experienced researcher in this field, includes chapters that cover biological treatments, reverse osmosis, and chemical-physical processes. This volume offers important research that will help us both assess our existing treatment facilities, as well as build better, more effective ones for the future.

This work presents the findings of an extensive study on the state-of-the-art regarding the problem of food waste in Belarus, Estonia, Germany, Latvia, Lithuania, Poland and Sweden. The results show that the problem of food waste can be found at different levels in each country and that our knowledge of it is limited by the current lack of studies in the area. The problem is primarily due to food waste generated by the manufacturing sector, mostly in the form of unused or inefficiently used by-products, as well as on a share of food thrown away by households that is still suitable for human consumption. The main reduction/prevention method, applied across the countries, is food donation; the remaining methods are the same ones used for biodegradable waste in the respective countries. The findings gathered in this study show a number of potential measures/methods for sustainable food waste management, which may be considered in future works in order to reduce the amounts of food waste generated in each of the aforementioned countries.

R2,423 R2,062 Discovery Miles 20 620 Save R361 (15%) Shipped within 7 - 12 working days

This book explores state-of-art techniques based on methodological and modeling aspects of solid and hazardous waste management, specifically focusing on the recent trends in data acquisition and robust modeling of the results obtained. In addition to an in-depth description of the recent regulatory paradigm for solid waste disposal and revealing insights into solid waste management models, the book also addresses significant case history and remediation methodologies for sustainable development in emerging economies like India, China and Brazil. The main emphasis is on a suitable regulatory framework with site-specific baseline calibration and aimed at the robust modeling of contaminant transport and its remediation. This is based on instructive case history in various locations/regions worldwide. The focus on recent modeling and quantification methods is the backbone of the book. One of the major aspects discussed is the application of non-invasive methods for studies related to the Earth's interior, which are increasingly preferred over invasive techniques thanks to their economic utility, as well as robust techniques for the interpretation of geophysical data. The increasing demand for groundwater and energy resources, especially for rapidly emerging countries with large populations like India and China, has made it vital to derive safe utilization approaches for our resources, including suitable waste disposal and remediation methodologies that can be adopted for 'contaminated sites.'

The Superfund program is the principal federal effort for cleaning up hazardous waste sites and protecting public health and the environment from releases of hazardous substances. The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) established the program, and the Superfund Amendments and Reauthorisation Act of 1986 (SARA) amended it. This book includes data and other pertinent information about CERCLA and the Superfund program, followed by a glossary. EPA defines brownfields as abandoned, idled, or under-used industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. FY1997 was the first year brownfields became a separate budgetary line item, at $37.7 million. For FY2000 the appropriation was $91.7 million. In the FY2001 budget, the Administration requested and was appropriated $91.6 million. The 106th Congress extended the brownfields cleanup tax incentive to December 31, 2003, and expanded it to make all brownfields certified by a state environmental agency eligible for tax break. Other brownfields bills introduced in the Congress appeared to confirm the general direction EPA has taken. Two Superfund reauthorisation bills were reported in the House, each of which contained a title on brownfields. The history, background and operations of the brownfields are described.

R4,695 Discovery Miles 46 950 Shipped within 7 - 11 working days

Hitherto the disposal of munitions was mostly concerned with obsolete stocks, but the political developments in the states of the former Soviet Union have necessitated the disposal of vast quantities of current and obsolete stocks. Obviously, open burning/open detonation cannot be used on such a large scale, not least for environmental considerations. There are two main technical problems associated with the disposal of munitions on the scale required. First, the materials are not simple wastes or rubbish. Their handling, storage, packaging and transportation are subject to very rigid regulation, and justifiably so, for obvious reasons. Second, they are very valuable goods, for which a high price has been paid by the holding states' economic systems. Mere destruction would mean the irretrievable loss of the value invested. But therein lies the problem. Goods like steel or brass scrap can easily be reclaimed, but hypergols and other rocket fuels (for instance) represent a true chemical challenge, while, under certain conditions, explosives may be diverted to civilian use. This, in summary, is the problem that the present book deals with: the two-pronged attack involving demilitarization and recycling technologies.

Public concern over the environmental and health risks posed by underground storage tank (UST) systems has given rise to myriad codes, standards, and regulations in recent years. In many states, UST owners, operators, contractors, and inspectors must prove that they understand how to apply a vast and growing body of technical and legal specifications to their work.

Technology of Underground Liquid Storage Tank Systems is based on John Hartmann's celebrated training course at the University of Wisconsin-Madison—the longest-running, most well-attended course of its kind. It was written for busy engineers, contractors, owner/operators, and inspectors who need to come up to speed on both the technology and the regulatory requirements involved in designing, installing, and closing USTs.

This complete, practical guide covers all the bases, from site assessment to damage control, regulatory compliance and legal considerations to project management. Drawing upon his 35 years of experience as a UST contractor and consultant, as well as the experience of several other leading experts in the field, Mr. Hartmann provides careful, step-by-step guidance and a gold mine of practical advice on how to avoid most technical and legal snags commonly encountered in building, maintaining, or removing USTs.

The European Union initially demonstrated its interest in waste in the late 70s with the progamme on Waste Recycling Research and Development. At that time composting was only present as a coordination activity and it was only later that specific research programmes in the area were within Europe which was largely instrumental in setting up a series of European conferences, seminars and work- shops. Some of these have resulted in publications which have made significant contributions to developments in the understanding of composting and the use of composts. In particular the outputs from meetings in Oxford ( 1984), Udine (1986), Neresheim ( 1988) and Angers ( 1991) are worthy of note. Composting has seen significant changes since the 70s when the major thrust in Europe was using mixed municipal solid waste as a feed material. Many com- posting plants which were built to use this material were closed due to the poor quality of the compost which made it very difficult to market. As a result the main areas of interest, as far as the municipa1ities are concemed, are now with biowaste and source-separated organics. This interest is apparent from the many new plants which are being constructed across Europe, and the ready market which exists for the products. In parallel with the renewed interest of the municipalities other areas, such as agriculture and the wastewater treatment industries, are also developing their own schemes.
