This book was released on 2005-01-01 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of cationic pollutant metals in municipal wastewater effluent is a concern because stringent discharge requirements cannot always be met with conventional treatment methods. Attempts to improve metal removal are often unsuccessful because a significant fraction of the cationic metals are complexed by the synthetic chelating agent ethylenediamine tetraacetic acid (EDTA). To identify practical approaches for improving metal removal, an analytical method for measuring metal-EDTA complexes was used to survey metal speciation at a series of wastewater treatment plants. Following these analyses, bench-scale experiments were conducted. The survey data indicated that pollutant metal-EDTA complexes account for a significant fraction of the dissolved metals in wastewater. The bench-scale studies indicated that ferric chloride addition improves the removal of copper and zinc by approximately 20%. To test the results of the bench-scale experiments, a full-scale experiment was conducted by interrupting chemical addition at a municipal wastewater treatment plant that normally adds ferric chloride during primary treatment. Results indicated that ferric chloride addition had a slight impact on metal speciation but no effect on metals removal. The lack of an effect was attributed to changes in metal speciation that occurred during primary treatment irrespective of ferric chloride addition.

This book was released on 2006-10-15 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated since the 1st Edition it has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. A thorough gamut of treatment scenarios is attempted, including turbidity, color and organics removal, including the technical aspects of enhanced coagulation. The effects of temperature and ionic content are described as well as the removal of specific substances such as arsenic and phosphorus. Chemical phosphorus removal is dealt with in detail, Rapid mixing for efficient coagulant utilization, and flocculation are dealt with in specific chapters. Water treatment plant waste sludge disposal is dealt with in considerable detail, in an Appendix devoted to this subject. Invaluble for water scientists, engineers and students of this field, Coagulation and Flocculation in Water and Wastewater Treatment is a convenient reference handbook in the form of numerous examples and appended information.

This book was released on 2005-03-11 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems 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 c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Book Synopsis Life Cycle Assessment and Water Management-related Issues by : Joaquim Comas Matas
Download or read book Life Cycle Assessment and Water Management-related Issues written by Joaquim Comas Matas and published by Documenta Universitaria. This book was released on 2012-09-03 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life Cycle Assessment is a scientific methodology to assess the environmental impact of a product, system or service along its life-cycle. This starts with the extraction of raw materials; follows with the manufacturing, distribution and use stages; and ends with the treatment of waste or byproducts. All this information allows us to avoid transfer of burdens between life cycle stages, geographical regions or environmental impact categories. For example, reducing the amount of material to manufacture a product (i.e. a washing machine, a car or a wastewater treatment plant) while not increasing energy consumption during its use or consumption.\nIn September 2012, from the 3rd to the 7th, the Laboratory of Environmental and Chemical Engineering (LEQUIA) and the Institute of the Environment of the University of Girona organized the 12th International Summer School for the Environment (ISSE) focused on “Life Cycle Assessment and Water issues”. It was framed within the European project Ecotech-Sudoe (www.ecotechsudoe.eu). Following the Lisbon Strategy, the research project Ecotech-Sudoe aims to merge sustainability and competitiveness. Ecotechnologies are powerful tools to achieve this, while providing the same level of service but with lower environmental and social impacts. They are based on emerging and promising research areas, such as social and environmental LCA (Life Cycle Analysis), ecodesign, and industrial and territorial ecology. \n\n\n
