This book was released on 2010-03-10 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to be a follow up of the WERF III (Adams, et al., 2007) odor study. It was found in the WERF III study that iron and aluminum appeared to play important roles in odor generation so some additional data was sought to determine the role these play in determining odor. In this portion of the study, the impact of iron and aluminum in sludges on both digestion and odors was investigated. Three distinct locations for the iron and/or aluminum were studied. First, the impact of iron and aluminum in the raw sludges on digestion and odors was evaluated. Second, the impact of the addition of iron or aluminum for chemical phosphorus removal in the activated sludge process was studied. Third, the direct addition of iron to the feed to an anaerobic digester was evaluated. All studies were conducted in the lab using a variety of sludges collected from seven wastewater utilities. In addition to digestion and odors, data were collected for sludge dewatering properties as indicated by the polymer conditioning requirements and dewatered cake solids. Both the iron and aluminum content in raw sludges being fed to anaerobic digesters impact the digestability, dewatering and TVOSC generation. A reasonable correlation between the iron content in the raw sludge and volatile solids reduction by anaerobic digestion was found. More iron resulted in higher volatile solids reduction except for the two plants that either received chemical sludge in the influent that contained iron and/or aluminum (Plant E) or had iron added in the treatment process (Plant F). This finding is important in that it provides for the prediction of digester performance based on the influent iron content. Aluminum appeared to also influence digestion, reducing the digestability of sludges. However, in this study, it was difficult to separate both the effects of iron and aluminum. Iron also had a major impact on dewatering. There was a distinct relationship between the iron content of the raw sludge and polymer dose requirements. As the iron increased, the polymer dose increased following digestion. As suggested in the WERF III report, iron appeared to play a role in TVOSC production from dewatered sludge cakes. As the iron content increased, the TVOSC generation increased. As a result, iron increases both the volatile solids reduction and TVOSC generation. The implication of this is that sludges that digest better also generate higher TVOSC. This has important implications for the regulations governing vector attraction based on volatile solids reduction. These regulations need to be changed or dropped from the regulations. Some of the data in this study shows a result that is contradictory to conventions thought. That is: as the volatile solids destruction increases, the TVOSC generation will also increase.

Download or read book Coagulation and Flocculation in Water and Wastewater Treatment written by John Bratby and published by IWA Publishing. 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.

Book excerpt: This encyclopedia is composed of an eight-volume set that provides an overview of the field of environmental analysis. The contents are divided into major content areas including air pollution control, environmental law, and environmental sampling. Thevolumes are organized alphabetically with each article signed by the author(s). The individual articles begin with a summary of the topic heading and then divide the text into subtopics indicated by boldface headings.The articles are written clearly, however, the authors assume a basic knowledge of chemistry and math on the part of the reader. For example, the acid mine drainage article refers to the Arrhenius equation, but does not clarify this statement in the text. Each article contains graphs as well as pictures to illustrate points made in the text. The articles are long and provide a detailed explanation of each topic. The authors also provide a bibliography at the end of each article.Special features of the encyclopedia include a list of contributors, a table of conversion factors and a list of abbreviations and acronyms. The preface outlines the general contents of the encyclopedia. The preface also includes sections that suggest the target audience and recommended usages for the set. The final volume of the set contains an alphabetic index to the topics contained in the volumes.

This book was released on 2005-06 with total page 1014 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 outlines water supply infrastructure. The requirements for supplying water to a home, a city or a factory can be very different. Experts in these fields explain the nuances of the details involved in maintaining adequate quantity and quality for these different consumers. Waste water management can be of even greater concern, yet its management can follow similar paths when compared to sophisticated water supply treatment. Both the physics and chemistry of these fields are fully covered. Volume 2 deals with the big picture of regional water supplies, how they become contaminated, how they can be protected and how they can best serve the surrounding populations and industries. Significant focus is placed upon the natural chemistry of available water supplies and its biological impacts. Case studies from regions around the world offer an excellent picture of the world's water resources.
