Download or read book Emerging Organic Contaminants in Sludges written by Teresa Vicent and published by Springer. This book was released on 2013-04-17 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are a growing number of new chemicals in the environment that represent an ascertained or potential risk. Many of them can be found in sewage sludge and are the subject of this volume. Experts in the field highlight their occurrence and fate, risks of biosolid use, advanced chemical analysis methods, and degradation techniques with a special focus on biodegradation using fungi. In the final chapter conclusions and trends are offered as a point of departure for future studies. The double-disciplinary approach combining environmental analysis and engineering makes the book a valuable and comprehensive source of information for a broad audience, such as environmental chemists and engineers, biotechnologists, ecotoxicologists and professionals responsible for waste and water management.
Book Synopsis Wastewater Treatment by : Amy J. Forsgren
Download or read book Wastewater Treatment written by Amy J. Forsgren and published by CRC Press. This book was released on 2018-10-08 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the sources of water contamination by PAHs and their transportation and fate in natural aquatic systems. It then discusses, from the analytical chemist’s view, how to determine the presence of PAHs in water and wastewater, and the changes in PAH concentration during treatment processes. The text examines the removal of PAHs using membrane bioreactors and advanced sludge processes, highlighting results from both demonstration and full-scale plants. It also examines the presence of PAHs in conventional wastewater treatment plants, especially in sludge.

Book Synopsis A Modified ASTM Semi-Continuous Activated Sludge Test to Compare Nonionic Surfactant Biological Removal by : PA. Filler
Download or read book A Modified ASTM Semi-Continuous Activated Sludge Test to Compare Nonionic Surfactant Biological Removal written by PA. Filler and published by . This book was released on 1995 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Semi-Continuous Activated Sludge (SCAS) test of the ASTM "Standard Test Method for Biodegradability of Alkylbenzene Sulfonates" (D2667-89) was modified and used to compare the biological removal of new carbohydrate-based surfactants (CBS). The SCAS test was modified in three ways: the units were miniaturized, natural sewage replaced synthetic sewage, and analysis for dissolved organic carbon (DOC) replaced methylene blue active substance as the analytical method. The modified test distinguished between compounds that underwent minimal to complete biological removal by establishing a percent removal at a "steady state" (typically reached within two weeks). The method is inexpensive, easy, and efficiently compares biological removal of surfactants or other water-soluble compounds. This study shows that random substitution of hydroxyl hydrogens on glucose inhibits biological removal. In contrast specific regio-substitution at the 3-O or 1-O positions did not inhibit biological removal.

Book Synopsis Molecular-based Analysis and Monitoring of Microbial Groups in Activated Sludge to Advance the Knowledge of Biological Processes in Wastewater Treatment by : Phillip Bernard Gedalanga

This book was released on 2010 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment has often depended on the activated sludge process to remove chemical or biochemical oxygen demand, nitrogen, and/or phosphorus from influent wastes. Treatment efficiency is dependent on microorganisms that are responsible for the oxidation of different substrates in these waters. Currently, biomass estimations at the full-scale level are based on suspended solids concentrations of the mixed liquor in the activated sludge process. This research was conducted under the hypothesis that the substitution of biomass represented as suspended solids for microbial quantities enumerated using molecular methodologies will advance the knowledge of biological processes in wastewater treatment. The primary objective was to determine relationships among specific bacterial abundance and physicochemical parameters that improve the treatment efficiency of activated sludge. DNA amplification technologies allow direct quantification of bacteria, which is the basis for population assessment in this research. Data collection consisted of physicochemical and biological analysis from the activated sludge process in a full-scale wastewater treatment plant. A number of treatment quality parameters were related to the abundance of total bacteria, ammonia oxidizing bacteria, and nitrite oxidizing bacteria in a partially nitrifying wastewater treatment plant. This research identified the influence of temperature and dissolved oxygen as key factors in the mechanisms for substrate competition between specific microbial groups, especially under oxygen limited conditions. Furthermore, the removal of biochemical oxygen demand was highly influenced by the major oxygen consumers in the activated sludge, namely heterotrophic bacteria and ammonia-oxidizing bacteria. The refinement of existing protocols, especially in the calculation of microbial kinetic parameters using specific biomass instead of a suspended solids estimate, is novel. This research has improved the understanding of the complex relationships between different microbial groups within activated sludge. Direct quantification of ammonia-oxidizing bacteria indicated a negative correlation with biochemical oxygen demand, therefore treatment quality can be optimized through stringent monitoring of this microbial group. Furthermore, insights into the interrelationships within nitrite-oxidizing bacteria have been gained via competition for substrate and variations in both environmental and plant operating parameters. The predominant nitrite-oxidizing bacterium was determined to be an important component of nitrite accumulation events. Ecophysiological factors were reaffirmed as the major source of population influence between total, ammonia oxidizing, and nitrite oxidizing bacteria in a full-scale wastewater treatment plant. Quantitative analysis of these populations elucidated operational adjustments that can be used to modify cell abundance and impact treatment efficiency. These results will be used for an improved microbial characterization of activate sludge and such determinations can positively influence wastewater treatment operations and efficiencies.
