This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Anaerobic-anoxic-oxic (A2/O) is one of the most widely used processes in municipal wastewater treatment plants for simultaneous biological nitrogen and phosphorus removal. The A2/O process has many advantages, such as simple configuration and short hydraulic retention time (HRT), etc. In addition, it is easy to operate. Therefore, A2/O will be continuously chosen as the main option in all kinds of newly designed and built wastewater treatment plants. Though the A2/O process has been used widely, it has some inherent contradictions which are difficult to overcome. For example, the contradiction between substrate competition and SRT makes the high nitrogen and phosphorus removal unable to be achieved simultaneously. As a result, the removal efficiency of the system cannot be further improved. In the past 10 years in China, the wastewater quality very obviously changed with the improvement of living conditions. At present, municipal wastewater with a low C/N ratio is rather common in most countries in the world. The lack of a carbon source will make the inherent contradictions of the A2/O process becomes serious. Therefore, the conventional design parameters of the A2/O process are needed to adjust or the configuration of the A2/O process should change to fit the change of the wastewater quality. According to this, this book systematically describes how to improve the nitrogen and phosphorus removal efficiency of municipal wastewater with low C/N ratio, and effectively utilize the carbon resource in the influent of wastewater. This publication is useful for students, researchers and engineers whose major focus is municipal and the environment"--

Available in PDF, EPUB and Kindle. Book excerpt: Water, energy, and food are basic requirements for life, and this book presents solutions for obtaining these from sewage wastewater treatment plants. It describes the optimal recovery of value-added products from municipal sewage plants in developing countries, and explains how the plants’ operations can become both economical and sustainable. Further, it shows how the clean effluent that is obtained is then suitable for agricultural use in the production of bio-fertilizers, and graywater for irrigation, and how the recovered biogas could be used for energy and heating needs. Practical case studies from three separate sewage plants are presented to illustrate the processes involved.

Available in PDF, EPUB and Kindle. Book excerpt: Many water resource recovery facilities (WRRF) around the world utilize biological processes for effective removal of nitrogen (N) from municipal waste; since biologically available N has been recognized as a significant pollutant in wastewater, is toxic to aquatic life and contributes to eutrophication. Over the past 30 years, discoveries of novel N-cycling microorganisms and biological pathways have been especially influential to energy-conscious WRRF research. Today, most biological N removal processes rely on extensive aeration for nitrification and organic carbon for denitrification; however, the high cost and loss of energy generating carbon associated with this type of treatment has propelled engineers and scientists to develop novel biological N treatment strategies that employ many of the newly discovered microorganisms and pathways. While energy-saving strategies are promising and have been employed full-scale, the microorganisms involved in some of these micro-aerobic N-cycling engineered ecosystems remain elusive. We have shown at the pilot-scale (treating full-scale primary effluent) that we can slowly transform an existing high-oxygen N-cycling microbial community to low oxygen concentrations, without loss of effluent quality, and with improved N removal efficiency [9]. Separate work with a bench-scale Madison Micro-Aerobic/AnoXic (MAD MA-AX) bioreactor has also shown that we can achieve up to 90% N removal with minimal aeration to treat the reject water from a struvite harvesting process. In both cases, we describe the key microorganisms contributing to N removal and discuss the factors that may lead to adaptation to microaerobic conditions.

This book was released on 2001 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of this study is to develop an innovative technology to treat nutrients especially and phophorous in domestic wastewater. This process is called the Anaerobic-anoxic-aerobic (AAA). Biological nitrification-denitrification and phosphorus removal in a single reactor have been shown applicable to treat nutrients with some modifications in an aerobic zonem where 'cosmo-ball' media were intoduced to enhance growth. The vertical reactor with 'up flow' influent was operated using a continuos system with an anaerobic-anoxic-aerobic zone sequence. This experiment was operated at HRT total of hours where the anaerobic, anoxic and aerobic zone takes 1.5, 1.5 and 4 hours respectively. The experimental run was conducted in the Enviromental laboratory using raw samples from an Extended Aeration treatment plant at Serdang Raya, Sri Kembangan, Selangor. The results showed that nitrification-denitrification process could be achieved using this anaerobic-anoxic-aerobic (AAA) reactor with 63% NH4-N removal and 51% PO4 removal. Removal of BOD, COD, TSS, VSS were 84%, 78%, 85% and 83% respectively. The results obtained also shows that organic and pH significance effects on nutrient removal for a medium strength wastewater. The treatment of sewage effluent was also carried out in anaerobix-anoxic-aerobic reactor to study the kinetics parameters for nitrification and denitrification processes and the results obtained were: YN = 0.041 mg VSS/mg NH4, Kd = 0.0417 day-1, μm = 1.6470 day-1, KN = 0.8996 mg/l (kinetic parameter for denitrification). Meanwhile, parameters kinetic for denitrification were: YD = 0.017 mg VSS/mg NO3, Kd1 = 0.0014 day-1, μm1 = 0.00407 day -1, KD = 8.036 mg/l. It has been found that there reactor was succeded in removing nutrients from the sewage.

This book was released on 2015 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater is treated biologically with activated sludge to remove the nutrients phosphorous and nitrogen. In accomplishing wastewater treatment, selecting for nitritation in the aeration phase can optimize the nutrient removal process to conserve energy and carbon, while enhancing phosphorous and nitrogen removal. This thesis investigated the ability of sequencing batch reactors (SBRs), operated in a unique post-anoxic denitrification mode (process referred to as BIOPHO-PX; trademark under development by Dr. Coats), to remove nutrients while controlling aeration length and residual DO concentration at different solids retention times (SRTs), with the goal to induce and sustain nitritation. Phosphorus removal of 97% and nitrogen removal of 82% were achieved with this process configuration.
