Pages : 3
Book Description
The purpose of this technical note is to discuss the mechanisms and rates of zebra mussel-assisted corrosion of ferrous metal surfaces. This information allows facility managers to better gauge the impact of the zebra mussel. This technical note replaces the earlier Technical Note ZMR-2-07, which should be discarded.

Aquatic Sciences and Fisheries Abstracts
Author: Microbicides for the Protection of Materials
Author: W. PaulusPublisher: Springer Science & Business Media
ISBN: 9780412534508
Category : Technology & Engineering
Languages : en
Pages : 526
Book Description
This book is chiefly intended for those who are using microbicides for the protection of materials. Another purpose is to inform teachers and students working on biodeterioration and to show today's technical standard to those engaged in R&D activities in the microbicide field. When trying to classify, or to subclassify, material-protecting microbicides according to their mode of action, e.g. as membrane-active and electrophilic active ingredients, it turned out that a clear assignment was not always possible. For that reason the author has resorted to chemistry's principle of classifying according to groups of substances (e.g. alcohols, aldehydes, ketones, acids, esters, amides, etc.), thus providing the first necessary information about the micro bicides' properties. The description of the various groups of substances includes, whenever possible, an outline of the mode and mechanism of action of the active ingredients involved. The effective use of microbicides presupposes knowledge of their character istics. That is why the microbicides' chemico-physical properties, their toxicity, ecotoxicity, effectiveness, and effective spectrum are described in greater detail. As mentioned before, the characteristics of microbicides play an important role. They have to be suited to the intended application to avoid detrimental effects on the properties and the quality of the material to be protected; also production processes in which microbicides are used to avoid disturbances by microbial action must not be disturbed by the presence of those microbicides.
Quagga and Zebra Mussels
Author: Thomas F. NalepaPublisher: CRC Press
ISBN: 143985436X
Category : Nature
Languages : en
Pages : 820
Book Description
The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.
Operational and Environmental Consequences of Large Industrial Cooling Water Systems
Author: Sanjeevi RajagopalPublisher: Springer Science & Business Media
ISBN: 1461416973
Category : Technology & Engineering
Languages : en
Pages : 491
Book Description
The use of water for industrial purposes is of foremost importance. It is used as a coolant and industrial activities dealing with power generation, steel and iron, paper and pulp and oil require very large amounts of water. The industry, therefore, resorts to large scale abstraction of water from natural water bodies. This water is often treated with chemicals to combat operational problems like biofouling and corrosion. Such withdrawal and subsequent discharge of large amounts of water have the potential to impart significant impact on the recipient water body. The organisms drawn along with the cooling water, as well as those residing at the discharge zone, are subjected to a combination of mechanical, thermal and chemical stress on a continuous basis.

Book Description
Like most technical disciplines, environmental science and engineering is becoming increasingly specialized. As industry professionals focus on specific environmental subjects they become less familiar with environmental problems and solutions outside their area of expertise. This situation is compounded by the fact that many environmental science
