This book was released on 2021-02-25 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotechnologies for wastewater treatment (EWWT) have been used as a cost-effective alternative to conventional wastewater treatment methods for improving the removal of organic carbon, nutrients and pathogenic microorganisms from wastewater. However, due to biochemical transformations of organic matter and nutrients EWWT are net sources of CO2, CH4 and N2O greenhouse gases (GHGs), which may be transferred into the atmosphere contributing to global warming. Greenhouse Gas Emissions from Ecotechnologies for Wastewater Treatment provides scientific information about greenhouse gas, such as CO2, CH4 and N2O, generation and emissions from different municipal EWWT. The main EWWT considered in this book are anaerobic ponds, facultative ponds, duckweed-based ponds, and a freshwater natural wetland perturbed by anthropogenic activities such as wastewater discharge and nutrients from agricultural run-off. The book includes a full literature review of recent publications about GHGs emissions from EWWT. It also introduces the calculation of GHGs flux using a static chamber technique. Besides, the book presents information on the influence of environmental factors such as temperature, pH, DO, and nutrients on GHG emissions produced in EWWT under tropical conditions. This book will be a useful reference for researches and students interested in the broader area of water and climate change subjects. The publication may also be of interest to policy makers concerned with climate change, water sector planning, and wastewater treatment.

This book provides a much-needed, comprehensive overview of the various types of wastewater and their ecotoxicological effects on the environment, humans, animals and plants as well as various emerging and eco-friendly approaches for their treatment. It provides insights into the ecological problems and challenges in the treatment and management of wastewaters generated by various sources.
Download or read book The Energy Greenhouse Gas Emissions and Cost Implications of Municipal Water Supply Wastewater Treatment written by Rodriguez-Winter Thelma and published by . This book was released on 2014 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of our drinking water and wastewater infrastructure are at the end of their useful life facing significant deterioration, causing leaks and water losses. These losses are a waste of both energy and water, considering both water and wastewater treatment systems are very energy intensive. In order to deal with the urban water infrastructure issues, EPA has listed out the following goals: asset management, water and energy efficiency, infrastructure financing, price of water services and alternative technologies assessment. This dissertation addresses two of EPA's goals, water and energy efficiency and alternative technologies assessment. Three approaches were taken to address these goals. In the first approach, the life cycle energy demand for water and wastewater studies were reviewed from literature to understand the energy requirements of these systems and propose a benchmark energy demand. System boundaries, data collection and reporting, type of LCA used, were identified as the factors that influence the total energy use and energy use reporting. Energy use data of water and wastewater treatment systems have been compiled to obtain ranges of 2.8 x 10-06 - 4.8 x 10-03 kWh per L and 2.8 x 10-09 to 1.32 x 10-02 kWh per L respectively. From the details obtained from literature, energy use ranges for specific processes related to water and wastewater could not be obtained due to lack of appropriate data reporting. Development of an appropriate data reporting procedure for water and wastewater treatment life cycle assessments is required to be able to collect, use and analyze this data. In the second approach, alternative technologies were assessed to reduce the energy requirements of the water and wastewater treatment systems. The quality of drinking water cannot be compromised; however, the use of potable water flushing toilets can be avoided to conserve energy and resources. In approach 2A Standard sanitation technology (Scenario 1) was compared with the following alternative technologies high efficiency toilets flushed with potable water (Scenario 2), standard toilets flushed with rainwater (Scenario 3), high efficiency toilets flushed with rainwater (Scenario 4), and composting toilets (Scenario 5). These technologies were compared on two University Buildings, based on cost, energy and carbon emissions using Economic Input Output Life Cycle Assessment (EIO-LCA). Based on all the three indicators, scenarios 4 and 5 were the most preferable scenarios. Life cycle assessments (LCAs) are done largely either using the economic input-output approach or process based approach. While both methods are commonly used, it is not well known how much the LCA results might change when one method is used instead of the other. In approach 2B the technologies from 2A were compared with the conventional sanitation technology using EIO-LCA and process based LCA. The results were overall higher from EIO-LCA except for potable water treatment. EIO-LCA was found better for modeling. The difference in magnitude for all products and processes involved is reported. More detailed documentation from both models is required for an explanation of the difference in magnitudes. There was no difference in the suggested ranking of scenarios from both the models. In approach three, composting toilets were studied in more depth. The composting toilets technology demonstrated potential for the most sustainable sanitation technology among all the five technologies compared. In approach 3A, the composting results however, were preliminary. A review of the available composting toilet technologies and the composting process was conducted to better understand the technology. The review, categorized the different types of composting toilets. Factors reported as affecting the composting process and their optimum values were identified as; aeration, moisture content (50-60 %), temperature (40-65oC), carbon to nitrogen ratio (25-35), pH (5.5-8.0) and porosity (35-50%). Barriers in implementing this technology were also identified. In approach 3B, Composting is an old technology and more popular only in rural areas that are disconnected from the urban water and wastewater infrastructure. The impact of using these technologies in urban areas on a large scale has not been evaluated before. In approach 3B, use of composting toilets with land application and back yard application of compost were modeled in GaBi for a tenth of the city and compared to the conventional sanitation system for the city of Toledo. Results show that composting toilets are beneficial if a tenth of the city shifts from conventional to composting technology.

This book was released on 2022-04-15 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increased commitment from the international community to reduce greenhouse gas (GHG) emissions from all sectors in accordance with the Paris Agreement, the water sector has never felt the pressure it is now under to transition to a low-carbon water management model. This requires reducing GHG emissions from grid-energy consumption (Scope 2 emissions), which is straightforward; however, it also requires reducing Scope 1 emissions, which include nitrous oxide and methane emissions, predominantly from wastewater handling and treatment. The pathways and factors leading to biological nitrous oxide and methane formation and emissions from wastewater are highly complex and site-specific. Good emission factors for estimating the Scope 1 emissions are lacking, water utilities have little experience in directly measuring these emissions, and the mathematical modelling of these emissions is challenging. Therefore, this book aims to help the water sector address the Scope 1 emissions by breaking down their pathways and influencing factors, and providing guidance on both the use of emission factors, and performing direct measurements of nitrous oxide and methane emissions from sewers and wastewater treatment plants. The book also dives into the mathematical modelling for predicting these emissions and provides guidance on the use of different mathematical models based upon your conditions, as well as an introduction to alternative modelling methods, including metabolic, data-driven, and AI methods. Finally, the book includes guidance on using the modelling tools for assessing different operating strategies and identifying promising mitigation actions. A must have book for anyone needing to understand, account for, and reduce water utility Scope 1 emissions.

Download or read book Estimation of Greenhouse Gas Emissions from Industrial Wastewater Treatment Plants written by Maziar Bani Shahabadi and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The outcome of Kyoto protocol and other National and International agreements influence the design and operation of wastewater treatment facilities by restricting their greenhouse gas (GHG) emissions. Wastewater treatment plants (WWTPs) are recognized as one of the larger minor sources of GHG emissions that produce CO 2, CH 4, and N 2 O during the treatment processes. The overall on-site and off-site greenhouse gas (GHG) emissions by WWTPs of food processing industry were estimated by using an elaborate mathematical model. Three different types of treatment systems were examined in this study which included aerobic, anaerobic, and hybrid anaerobic/aerobic processes. The overall on-site emissions were 1952, 1992, and 2435 kg CO 2 e/d while the off-site emissions were 1313, 4631, and 5205 kg CO 2 e/d for the aerobic, anaerobic and hybrid treatment systems respectively. The on-site biological processes made the highest contribution to GHG emissions in the aerobic treatment system while the highest emissions in anaerobic and hybrid treatment systems were obtained by off-site GHG emissions due to on-site material usage. Biogas recovery and reuse as fuel were shown to cover the total energy needs of the treatment plants for aeration, heating and electricity for all three types of operations, and considerably reduced GHG emissions by 512, 673, and 988 kg CO 2 e/d from a total of 3265, 6623, and 7640 kg CO 2 e/d for aerobic, anaerobic, and hybrid treatment systems, respectively. In the end, recommendations were given on feasible approaches to reduce GHG emissions from WWTPs.
