This book was released on 2004-03-01 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was undertaken in response to needs by the wastewater treatment industry to better understand the generation of odors from biosolids produced by wastewater treatment plants (WWTPs). Its primary objective is to begin to establish relationships between WWTP process parameters and biosolids odors, so that more effective techniques for minimizing biosolids odors can be developed. The project consisted of a detailed field study involving extensive sampling and analyses at 11 WWTPs across North America with capacities from 13 to 350 million gallons per day (mgd). Biosolids samples were collected from the WWTPs at a number of sampling points, which were chosen to represent a complete snapshot of biosolids generation and handling at each WWTP. The sampling points started with influent wastewater, proceeded through primary and secondary clarification, and continued through digestion, dewatering, and onsite storage of dewatered biosolids cake. Laboratory-scale anaerobic storage tests were conducted to simulate odor development of biosolids in storage, prior to their beneficial reuse or disposal. A battery of analyses were performed on the biosolids samples by the participating utility laboratories, commercial laboratories, and specialized university laboratories. The analytical data were evaluated and compared with process and operation parameters at each participating WWTP.

Book Synopsis Biosolids Applied to Land by : National Research Council
Download or read book Biosolids Applied to Land written by National Research Council and published by National Academies Press. This book was released on 2002-11-01 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1993 regulation (Part 503 Rule) governing the land application of biosolids was established to protect public health and the environment from reasonably anticipated adverse effects. Included in the regulation are chemical pollutant limits, operational standards designed to reduce pathogens and the attraction of disease vectors, and management practices. This report from the Board on Environmental Studies and Toxicology evaluates the technical methods and approaches used by EPA to establish those standards and practices, focusing specifically on human health protection. The report examines improvements in risk-assessment practices and advances in the scientific database since promulgation of the regulation, and makes recommendations for addressing public health concerns, uncertainties, and data gaps about the technical basis of the biosolids standards.

Book Synopsis Biological Phosphorus Removal by : P. M. J. Janssen
Download or read book Biological Phosphorus Removal written by P. M. J. Janssen and published by IWA Publishing. This book was released on 2002-05-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological phosphorus (bio-P) removal has become a reliable and well-understood process within wastewater treatment, despite being one of the most complex processes in the activated sludge process. Extended fundamental and full-scale research has been carried out into the bio-P process and the state-of-the-art is described in this report. A summarising historical overview gives insight into the establishment of the appropriate microbiological and biochemical basis of the process and the development of bio-P configurations in practice. Aspects of the bio-P process that have a direct influence on the efficiency of phosphorus removal are subjected to an in-depth investigation. This report presents guidelines for design and dimensioning in order to introduce and/or optimise the bio-P process in practice. Twelve bio-P installations are extensively described and the operational results and experiences are related to existing bio-P knowledge and guidelines. Based on a number of parameters, a comparison is made between the described bio-P plants. A steady state model is verified with extensive periods of practical experience of the plants. The bio-P model, which is provided on CD-ROM (available for download here), offers a reliable insight into the bio-P process, coupled with sensitivity analyses regarding wastewater characteristics and process parameters for the anaerobic volume and the P-ortho concentration in the final effluent. The report ends with a systematic approach to the design of the bio-P process, based on the background of the bio-P process itself, much practical experience and the analysis of operational bio-P plants. Also presented is a systematic approach to tackle operational aspects of the bio-P process in order to generate an acceptable low P effluent concentration. This optimisation of the bio-P process operation is supported by a decision diagram. Biological Phosphorus Removal will be an invaluable source of information for all those concerned with wastewater treatment, including plant managers, process designers, consultants and researchers.

Book Synopsis Odours in Wastewater Treatment by : Richard M. Stuetz
Download or read book Odours in Wastewater Treatment written by Richard M. Stuetz and published by IWA Publishing. This book was released on 2001-03-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment works have the potential to generate unpleasant odours, which can results in annoyance and consequently have a detrimental effect on a local population. As a result 'odour control and prevention' has become an important consideration both in the management of existing facilities and in the design and gaining of planning consent for new works. Odours in Wastewater Treatment provides readers with a detailed discussion on the basic principles involved in the formation of volatile compounds in wastewater treatment. Accounts are given of recent developments in the sampling and measurement of odours, practical examples in the prediction and dispersion of odorous emissions are offered and an overview of the technologies currently used to contain and treat odorous compounds presented.

This book was released on 2017 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Odor nuisance has been a challenge to management of wastewater treatment plants (WWTPs) and endanger the relationship between these facilities and neighbors. A systematic methodology was developed to investigate and understand odor nuisances from WWTPs, and provide practical solutions to solve these problems. The study of this methodology includes the incorporation of both chemical and sensorial methods, optimization of sampling techniques, development of analytical methods for specific odorants, and understanding the masking effect of odorous mixtures. Both sensorial and chemical methods should be applied to investigate odor nuisance from wastewater facilities. Using chemical analysis alone is not able to clarify the problem because there is a gap between the method reporting limit (MRL) and odor threshold concentration (OTC) of odorants. Sensorial methods, such as odor profile method (OPM) and Detection/Threshold (D/T) method should be used to bridge the gap. The OPM can determine the major odors presented and their intensities, and then narrow the major potential odorants to a manageable group. D/T determines the total odor and if there is an odor nuisance problem, while the OPM can define the odors and their intensities. The losses of volatiles and odorants in sampling bags have been reported in literature. Thus, the proper choice of sampling bags is needed for both sensorial and chemical analysis. The stability of wastewater odorants samples in sampling bags of Tedlar (polyvinyl fluoride film) and Teflon FEP (fluorinated ethylene propylene film) was evaluated and compared. Quick losses of indole and skatole were found in Tedlar bag, with less than 5% left after 15 minutes due to adsorption on the bag wall, while skatole and indole showed over 75% recovery over 6 hours in Teflon bags. Thus, Teflon bags are required for the analysis of skatole and indole, which needs to occur within 6 hours of sample collection. Teflon bags also are preferred for both chemical and sensory analysis due their lower background of chemical and odorant contamination. Sensory- gas chromatography (Sensory GC) and GC-mass spectroscopy (GC/MS) with the OPM can identify primary odor causing chemicals that are causing the odor nuisance. GC-MS was applied to investigate the chemical sources of fecal and musty odorants identified by the OPM. Skatole and indole were found to be the primary chemicals leading to fecal odor, due to its odor concentration/ OTC (C/OTC) ratio that ranged from 2.8 to 22.5. 2-Methylisoborneol (MIB) and 2-isopropyl-3-methoxypyrazine (IPMP), that have been reported to cause musty odor in drinking water supplies, were identified as principal contributors to the musty nuisance odor at the WWTPs odor sources. The present ability of WWTP odor control treatment of these fecal odorants by different air pollution control methods was evaluated at different locations at two WWTPs by the OPM and indole and skatole chemical analysis. Chemical scrubbing and biofiltration performed best in removing fecal odors among current control technologies. The C/OTC ratio is a simple method to prioritize the odorants and employ both chemical and sensorial results to help eliminate them. The OTC of the nine "most detectable" odor characteristics by the OPM and D/T method and the odorants associated with these odors by the GC-MS and GC-Sensory Analyses at two WWTPs were determined based on Weber-Fechner curve. The Weber-Fechner Curve relates the Log of the Odor Intensity of each chemical causing the odor versus the Log of the Concentration of each odorant. The OTC of 2-isopropyl-3-methoxypyrazine (0.02 ng/L in air), methyl mercaptan (0.2 ng/L in air), 2-methylisoborneol (0.1 ng/L in air), and skatole (0.3 ng/L in air) were quite low. As dilution occurred, the intensities of both the fecal and the sulfur odors decreased. At the greater dilutions, musty odors appeared and the fecal and sulfur odors became undetectable. This is a masking of the odor, which is called "peeling the onion" effect. This masking effect was successfully evaluated in this study. Thus, this thesis for the first time identified and quantified the fecal odorants (indole and skatole), the musty odorants ( IPMP and MIB) that cause odor nuisances from WWTPs, Analytical methodologies using the correct sampling bags were defined for the OPM and chemical analysis of these odorants. Also this thesis developed knowledge of the odor masking effect by odorous mixtures that are not sensorially observed at the WWTP, but could be observed off-site as an odor nuisance.
