The generation of wastes as a result of human activities has been continuously speeding up since the beginning of the industrial revolution. Hence, both optimized waste water treatment technologies and modern tools to assess the effects of pollution sources are necessary to prevent the contamination of aquatic ecosystems The book offers an interdisciplinary collection of topics concerning waste water treatment technologies, water quality monitoring and evaluation of waste water impact on natural environments.

Many things have changed, but many things have stayed the same since the first
was published. One thing that has stayed
the same is that this is still the most exciting technical area in the remediation field
today. Also, many new important technologies have emerged over the past 5 years,
and full-scale installations of existing technologies have broadened our knowledge
base. The purpose of this book is to provide the reader with a single source that
consolidates all of this information on the various
This volume covers the technologies that are applied to the treatment and
purification of water. Those who are generally familiar with this field will
immediately embrace the subject as a treatise on solid-liquid separations. However,
the subject is much broader, in that the technologies discussed are not just restricted
to pollution control hardware that rely only upon physical methods of treating and
On average, one ton of hazardous waste per person is generated annually
by industries in the United States. Before the Resource Conservation and
Recovery Act of 1984, hazardous wastes were improperly disposed of into
the environment without any regulation. As a result, remediation of these
contaminated sites and management of the ongoing hazardous waste sources
are two major tasks to be achieved by treatment technologies.
In order to maintain economic development and minimize future regional and
international conflicts, the United States will need sustainable supplies of high-quality fresh water. Solutions to local water scarcity issues will likely require a combination of approaches, including demand management, improved water storage capacity, water
quality protection, and advancements in supply-enhancing water treatment technologies. Desalination technologies can create new sources of freshwater from otherwise impaired waters such as seawater or brackish water.
Handbook of Water and Wastewater Treatment Plant
, the intent of the author is twofold. The Þrst
intent is to consolidate the information and experience in
waterworks and wastewater treatment plant operations
that have evolved as a result of technological advances in
the Þeld, and as a result of the concepts and policies
promulgated by the environmental laws and the subsequent
The steady increase in industrialization, urbanization and enormous population
growth are leading to production of huge quantities of wastewaters that may frequently
cause environmental hazards. Raw or treated waste water is very oft en discharged
to freshwaters and results in changing ecological performance and biological diversity
of these systems. About 70% of water supplied ends up as wastewater and several natural
water reservoirs are being contaminated by untreated sewage/industrial effl uents.
This makes waste water treatment and waste water reduction very important issues....
The detection of pharmaceutical residues remained elusive until instruments such as liquid chromatography and mass spectrometry became commonplace in environmental laboratories. The documentation of the occurrence of pharmaceutical residues and endocrine disrupting chemicals in water resources has raused questions about their long-term effects in the ecosystem and their potential effects on human health.
AD HOC NETWORKS: Technologies and Protocols is a concise in-depth treatment of various constituent components of ad hoc network protocols. It reviews issues related to medium access control, scalable routing, group communications, use of directional/smart antennas, network security, and power management among other topics. The authors examine various technologies that may aid ad hoc networking including the presence of an ability to tune transmission power levels or the deployment of sophisticated smart antennae. ...
The first edition of the Steel Heat Treatment Handbook was initially released in 1997. The objective of that book was to provide the reader with well-referenced information on the subjects covered with sufficient depth and breadth to serve as either an advanced undergraduate or graduate level text on heat treatment or as a continuing handbook reference for the designer or practicing engineer.
Environmental considerations: treatment of exhaust gases from film-coating processes
Graham C.Cole SUMMARY Solvents such as acetone, methylene chloride, chloroform, ethanol and methanol must be prevented from entering the environment. Two options are available: convert all the processes to aqueous-based formulations or recover all the solvent by the use of an appropriate system. Recovery is expensive and is generally the reason for pharmaceutical companies to convert coating formulations to aqueous systems or formulate aqueous coating for all new products.
This book is targeted to graduate students and researchers at the cutting edge of investigations into the fundamental nature of multiphase flows. It is intended as a reference book for the basic methods used in the treatment of multiphase flows. The subject of multiphase flows encompasses a vast field whose broad spectrum presents a problem for the experimental and analytical methodologies that might be appropriate for the reader's interests.
Modified release coatings
John E.Hogan SUMMARY Relevant aspects of the composition and performance of modified release coatings are considered in this chapter. Initially, the basic characteristics of multiparticulate systems are described and comparisons are made with the performance of whole tablets intended for modified release. The properties and effects of the polymers and plasticizers which are used in modified release coatings are illustrated with examples from the literature. This further develops the basic treatment of these materials provided in Chapter 2.
This book examines the practices used or considered for
biological treatment of waterlwastewater and hazardous wastes.
The technologies described involve conventional treatment
processes, their variations, as well as recent research. The book
is intended for those seeking an overview of the field, and covers
the major topics. The book is divided into five principal sections,
and references are provided for those who wish to dig deeper.
A new technology for production of 4BS pastes for the positive (lead dioxide) plates of lead-acid batteries has been developed based on an Eirich Evactherm1 mixer. The basic principle of this new technology is that 4BS crystals with dimensions between 20 and 25 mm are formed ®rst from a semi-suspension at a temperature higher than 908C and then the excess water is removed from the semi-suspension under vacuum until the desired paste density is obtained. During the vacuum treatment the temperature of the paste decreases and small 4BS and PbO crystals are formed. ...
This recent technology separates the corn kernel into its components
without the soaking step. Depending on the process—several companies
currently offer similar technologies—the feedstock may be misted with
water before being separated into bran, germ, and the high-starch
endosperm portion of the kernel (BioFuels Journal, 2005d,e).
The advantages of dry fractionation over processes that require a soak step
are threefold: lower costs because less energy is required for drying the feed
coproduct, lower emissions, and greater coproduct output because the mash
is more highly concentrated.

Breast cancer remains a leading cause of cancer death among women
in the United States. More than 180,000 new cases of invasive breast
cancer are diagnosed each year, and more than 40,000 women die of the
disease. Recent years, however, have seen improvements in survival
attributed to better treatment and earlier diagnosis. Research efforts have
been directed toward better treatment, preventive strategies, and early
What have been the impacts of the GGDP-generated maize technologies? In the absence of reliable baseline data, it was not
possible to calculate quantitative measures of project impact. Based on farmers’ qualitative judgments, however, it is clear that
adoption of the GGDP-generated technologies has been associated with significant farm-level productivity gains (measured
in terms of maize yields) and noticeable increases in the income earned from sales of maize. Impacts on the nutritional status
of rural households, however, appear to have been less pronounced.
