Industrial Waste Treatment Handbook provides the most reliable methodology for identifying which waste types are produced from particular industrial processes and how they can be treated. There is a thorough explanation of the fundamental mechanisms by which pollutants become dissolved or become suspended in water or air. Building on this knowledge, the reader will learn how different treatment processes work, how they can be optimized, and the most efficient method for selecting candidate treatment processes. Utilizing the most up-to-date examples from recent work at one of the leading environmental and science consulting firms, this book also illustrates approaches to solve various environmental quality problems and the step-by-step design of facilities. * Practical applications to assist with the selection of appropriate treatment technology for target pollutants. * Includes case studies based on current work by experts in waste treatment, disposal, management, environmental law and data management. * Provides glossary and table of acronyms for easy reference.

Combined Sharon/Anammox Process IWA Publishing

Książki / Literatura obcojęzyczna

Wastewater treatment management, alongside many other industries, is seeking to attain a higher degree of sustainability for its processes by focusing on new technologies which minimise the consumption of resources or even recover them from the wastewater. Conventional removal of ammonium requires usually large amounts of energy for aeration and organic carbon for denitrification. This report focuses on making the nitrogen-removal process more sustainable. This can be achieved by a partial oxidation of ammonium to nitrite, after which the nitrate produced can be converted into nitrogen gas with the rest of ammonium under anoxic conditions. The treatment of nitrogen-rich water can be carried out beneficially by a combination of the Sharon process with the Anammox process. In this combined process less than 50 per cent of the aeration energy is needed, no COD is required and an insignificant amount of sludge is produced. In this Report the potential of using this technology for the treatment of water arising from sludge treatment at a municipal wastewater treatment plant (WWTP) is evaluated and the results of the operation of the system are described in detail. This reject water contains a significant fraction of the N-load towards the wastewater treatment plant. The results are used in an economic evaluation of a potential full scale installation. The Combined Sharon/Anammox Process Report will provide an invaluable source of information for all those concerned with the efficient and sustainable treatment of wastewater including plant managers, process designers, consultants and researchers.

Impact of UV Disinfection on Biological Stability - 2212827245

Impact of UV Disinfection on Biological Stability IWA Publishing

Inne 1

Interest in UV disinfection has increased significantly in recent years, due its ability to inactivate Cryptosporidium parvum. Although UV disinfection shows significant promise for inactivation of Cryptosporidium, very few investigations have examined the impact of UV disinfection on biological stability in distribution systems. Biologically stable water is defined as drinking water that does not promote the growth of microorganisms and is typically achieved either through the removal of substrate and/or by providing a secondary disinfectant. At present there is little information concerning potential synergies between UV treatment and secondary disinfectants for improving biological stability. The overall objective of the research was to evaluate the effect that UV disinfection has on biofilm growth in drinking water distribution systems. In addition, the project's sub-objectives were to (1) determine the potential synergistic effects between primary disinfection with UV treatment and secondary disinfection for controlling bacterial regrowth; (2) compare the effectiveness of chlorine dioxide, free chlorine, and monochloramine for limiting bacterial regrowth in the presence and absence of UV treatment; (3) characterize the chemical intermediates formed during UV/CI2 photocatalysis of natural organic matter; and (4) examine the potential impact of UV/CI2 treatment on the biodegradability of natural organic matter (NOM) for three drinking water utilities. The research was conducted in three phases: Phase 1 provided a direct comparison of chlorine---based disinfectants following UV disinfection; Phase 2 examined the biodegradability of humic material that had been photocatalyzed with UVICI2; and Phase 3 characterized the organic by--products produced following UVICI2 catalysis of post-filtered water obtained from three water utilities. Phases 1 and 2 were conducted at bench-scale using annular reactors (ARs) to monitor bacterial regrowth. Phase 3 was conducted at bench-scale with a batch biodegradation study to monitor bacterial growth, by-product production, and organic degradation. During Phase 3, post--filtered water was collected from three water utilities and determination of biodegradability was completed.

Overview of State Energy Reduction Programs and Guidelines for the Wastewater Sector IWA Publishing

Książki / Literatura obcojęzyczna

Approximately 35% of a wastewater treatment facilities' total cost to provide wastewater service is for energy use. Industry wide, about 0.6% of the electric energy produced in the United States is consumed by commercial sector wastewater treatment. Clearly, the wastewater sector and other wastewater treatment providers, such as industry and commercial establishments, need cost-effective solutions for energy management and efficiency in their wastewater treatment operations. The interrelated problems of rising energy costs and demand alongside climate change have brought the issue of energy efficiency into the forefront of most every wastewater treatment provider today. The Operations Optimization Challenge is the Water Environment Research Foundation's (WERF) program to build integrated, comprehensive, long-term research into process optimization, energy efficiency, energy and resource recovery, and minimization of the environmental footprint of wastewater collections and treatment. The primary goal of the Optimization Challenge is to develop approaches that allow the wastewater sector to attain a 20% or greater reduction in energy to achieve treatment goals. One of the goals of the Operations Optimization Challenge is to identify the approaches used by the most effective power utility or state energy efficiency programs. Using these most effective elements of these programs build upon success and promote energy efficiency at the facility by putting in place the framework for effective energy management at a higher level. Currently only four states have effective energy reduction programs with a long-term history of performance. This report is aimed at increasing the number of states or other agencies (interstate agencies as well as power providers) who can implement successful programs to assist the wastewater sector reduce nationwide energy demand. In support of this goal, this report: Provides suggested language for incorporating energy efficiency related concepts in design guidelines or standards. Evaluates the feasibility of establishing a national design standard for wastewater treatment facilities which incorporates energy efficiency related concepts in an outlined model standard. This includes results from a technical working session of selected wastewater regulatory and energy regulatory agencies that was focused on the issue of incorporating energy guidelines in their respective standards. Identifies reviews and analyzes successful state and utility sponsored wastewater-related energy programs and suggests a model framework based on the key elements of these programs.
