Available in PDF, EPUB and Kindle. Book excerpt: This report reviews existing and newly developed analytical methods for sewage sludge analysis. ft had been stressed earlier that knowledge of the form of metals in waste and environmental samples is of great importance. As a result of this the development of simple equipment and analytical methods to initiate metal speciation has been stressed. Procedures developed earlier and used provisionally have been studied in depth. The mercury method is now acceptable as recorded. The As/Se procedure has been modified as a result of further investigation. Nonflame atomic absorption methods have been developed for silver and vanadium. It is demonstrated that using atomic absorption spectroscopy as a detector does not guarantee a quick solution to metal speciation problems. Sludges can be dry-ashed at 450°C without fear of Joss of cadmium, lead or appreciable amounts of zinc. When aluminum is to be determined, dry-ashing should not be used. Data also make it clear that incineration at temperatures usually employed will release large amounts of arsenic, cadmium, lead, mercury and zinc. A number of sewage sludges were analyzed, and the results are tabulated.

This book was released on 1996-02-26 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the practice of reclaiming treated municipal wastewater for agricultural irrigation and using sewage sludge as a soil amendment and fertilizer in the United States. It describes and evaluates treatment technologies and practices; effects on soils, crop production, and ground water; public health concerns from pathogens and toxic chemicals; existing regulations and guidelines; and some of the economic, liability, and institutional issues. The recommendations and findings are aimed at authorities at the federal, state, and local levels, public utilities, and the food processing industry.

Available in PDF, EPUB and Kindle. Book excerpt: Sludge Treatment and Disposal is the sixth volume in the series Biological Wastewater Treatment. The book covers in a clear and informative way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described. About the series: The series is based on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other titles in the series are: Volume 1: Waste Stabilisation Ponds; Volume 2: Basic Principles of Wastewater Treatment; Volume 3: Waste Stabilization Ponds; Volume 4: Anaerobic Reactors; Volume 5: Activated Sludge and Aerobic Biofilm Reactors
Download or read book Wastewater written by Pay Drechsel and published by Springer. This book was released on 2015-03-11 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The books provides a timely analysis in support of a paradigm shift in the field of wastewater management, from ‘treatment for disposal’ to ‘treatment for reuse’ by offering a variety of value propositions for water, nutrient and energy recovery which can support cost savings, cost recovery, and profits, in a sector that traditionally relies on public funding. The book provides new insights into the economics of wastewater use, applicable to developed and developing countries striving to transform wastewater from an unpleasant liability to a valuable asset and recasting urbanization from a daunting challenge into a resource recovery opportunity. “It requires business thinking to transform septage and sewage into valuable products. A must read for water scholars, policy makers, practitioners, and entrepreneurs". Guy Hutton, Senior Economist, Water and Sanitation Program, Water Global Practice, World Bank “This book provides compelling evidence and real solutions for the new ‘resource from waste’ approach that is transforming sanitation, boosting livelihoods, and strengthening urban resilience”. Christopher Scott, Professor and Distinguished Scholar, University of Arizona “This book shows how innovative business thinking and partnerships around resource recovery and reuse fit well within an inclusive green economy and climate change adaptation and mitigation strategies”. Akiça Bahri, Coordinator of the African Water Facility, Tunisia, and award-winning researcher

Available in PDF, EPUB and Kindle. Book excerpt: Lysimeter experiments in which crops were grown on agricultural soils treated with anaerobically digested sewage sludges (from plants where phosphorus removal was being practised using metal salts) were initiated in 1972 and 1973. Alum, iron and lime treated fluid sludges were added to loamy sand and silt loam soils vegetated with orchard grass. Similarly, alum, iron and lime treated air-dried sludges were added to sand and clay soils and wheat crops were grown. The high application rates of fluid and air-dried sludges ranged From 32 to 76 and 47 to 144 tons dry wt/ha/yr, respectively. The metal loadings approximated the recommended maxima for Ontario agricultural land. The lower rates were one-third and two-thirds of the high rates. The results of these experiments are presented and compared to results from field and greenhouse studies. There was no evidence that the aluminum, iron or lime in the digested sludges was detrimental to crop production or plant tissue quality. Orchard grass yields from the f1uid sludge experiment appeared to be related to nitrogen avai1abi1ity. Ìn general t land application of sewage sludges at rates sufficient to supply the crop uptake of N and P would limit soil heavy metal loadings to acceptable levels for the sludges used in these lysimeter studies.
