Human activity is strictly linked with the production of waste, i.e., materials and substances that are undesired and cannot be used further. On the one hand these substances are natural to the environment, eliminated from further technological process by their uselessness (e.g. mining waste), or represent new products such as anthropogenic waste, being the by-product of industrial and agricultural activities. A separate group comprises municipal waste that is not linked with production but results from human dwelling. Utilisation actions aiming at neutralising and/or removal of waste are focused on substances that due to their existing or potential chemical activity may negatively influence the biosphere. Non-active substances represent alien elements in the natural environment, but due to their passive character, their utilisation is concentrated on non-conflicting storage. Active pollutants influencing the natural environment penetrate it as gaseous emanations, fluids (sewage and effluents) and solids. This book addresses this very important issue and covers the topic of restriction of emission and removal of hazardous gaseous emanations that should be conducted in places where they are formed. Imperfection of the applied technology or its lack results in atmospheric pollution. This problem can be of local (around industrial plants, e.g. chemical works, food processing plants, around farmsteads and stock farms), country or global range (emission of CO2, nitrogen compounds, gases hazardous to the ozone layer).

Wastewater treatment plants usually generate millions of tons of sewage sludge every year. Sewage sludge results from the accumulation of solids from chemical coagulation, flocculation and sedimentation during wastewater treatment. Worldwide, sludge production is steadily increasing, driven by the increasing percentage of households connected to central treatment plants, the increasing tightening of pollution limits on the effluent discharged, as well as the availability of technologies capable of achieving higher efficiency of wastewater treatment. Sewage sludge contains undesirable hazardous substances such as trace elements, pesticides and endocrine disruptors, pathogens and other microbiological pollutants. Therefore, sludge has to be properly treated and disposed of to prevent environmental contamination and health risk. Sludge processing is intended to improve dewatering characteristics, eliminate disease-causing bacteria, reduce smell and decrease the quantity of organic solids. In this way, the end product can be treated further or disposed of with less handling problems and environmental consequences. This new important book gathers the latest research from around the globe on this issue.

Sewage is mainly a liquid waste containing some solids, produced by humans. It typically consists of washing water, faeces, urine, laundry waste and other material which goes down drains and toilets from households and industry. Sewage sludge is an end product of the wastewater treatment process. This material can be a wonderful source of nutrients for the soil. This book provides current studies and research on the treatment and use of sewage. Using this material as a fertiliser can benefit the environment by turning wastes into valuable resources. These sludges would otherwise have to be disposed of by landfilling, lagooning, incineration, or ocean dumping. On the other hand, heavy metals sometimes found in sewage sludge may present environmental problems as there is filtration of metals towards the aquifers which get contaminated. This book addresses these concerns as well as benefits.

R6,426 Discovery Miles 64 260 Ships in 12 - 19 working days

Approximately 15,000 combined sewer overflow events (CSOs) occur annually. During peak storm events they can release about 1.2 trillion gallons of waste and up to 95% of a municipality's raw sewage into surface waters. Although many cities have initiated programs, the CSO problem remains largely unsolved and continues to be a major area of responsibility for environmental professionals, engineers, and public works officials.

Sponsored by the EPA, written by internationally recognized experts, and subjected to extensive peer review, Management of Combined Sewer Overflows provides the latest information on the subject from analysis of contaminants to long-term CSO control plans. Coverage includes:

" CSO analysis and characterization of contaminants
" Analysis and characterization of receiving-water impacts
" Methods of control such as storage, treatment, disinfection, and systems optimization
" Regulations and compliance
" Systems retrofits and upgrades
" Long-term CSO control plans
" Research and design needs

Abatement or prevention of pollution stormwater runoff and CSOs is one of the most challenging areas in the environmental engineering field. The facts of life - from an engineering standpoint - are difficult to face in terms of design and cost. And operational problems can be just as foreboding. A reference for anyone combating urban wet-weather-induced water pollution, Management of Combined Sewer Overflows covers the gamut of engineering requirements, from pollution problem assessment and associated tools, to management and control planning and design.

A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application. The time is right for a reference that discusses the technology and its application in wastewater purification.

Wastewater Purification: Aerobic Granulation in Sequencing Batch Reactors discusses state-of-the-art research and application of this environmental biotechnology tailored to enhanced wastewater purification. The seventeen chapters provide a systematic and comprehensive understanding of aerobic granulation in SBR by incorporating fundamental principles of aerobic granulation withthe basis of process operation under various conditions. The book clearly explains what aerobic granules are and how they form. It elucidates key factors that influence aerobic granulation and addresses common problems encountered and their solutions.

This is the first book-length exploration of aerobic granulation. Other books that cover it are smaller, less comprehensive, less in depth, and less up to date. This book provides first-hand information derived from the authors' research and presents a newly-developed theory for aerobic granulation that offers a deep understanding into the essence of current aerobic granulation technology. Using this book as a platform, the technology can bedeveloped further and quickly applied in the wastewater treatment industry.
