Autotrophic Nitrogen Removal from Low Concentrated Effluents


Book Description

On a global scale, sewage represents the main point-source of water pollution and is also the predominant source of nitrogen contamination in urban regions. The present research is focused on the study of the main challenges that need to be addressed in order to achieve a successful inorganic nitrogen post-treatment of anaerobic effluents in the mainstream. The post-treatment is based on autotrophic nitrogen removal. The challenges are classified in terms of operational features and system configuration, namely: (i) the short-term effects of organic carbon source, the COD/N ratio and the temperature on the autotrophic nitrogen removal; the results from this study confirms that the Anammox activity is strongly influenced by temperature, in spite of the COD source and COD/N ratios applied. (ii) The long-term performance of the Anammox process under low nitrogen sludge loading rate (NSLR) and moderate to low temperatures; it demonstrates that NSLR affects nitrogen removal efficiency, granular size and biomass concentration of the bioreactor. (iii) The Anammox cultivation in a closed sponge-bed trickling filter (CSTF) and (iv) the autotrophic nitrogen removal over nitrite in a sponge-bed trickling filter (STF). Both types of Anammox sponge-bed trickling filters offer a plane technology with good nitrogen removal efficiency.




Assessing sanitary mixtures in East African cities


Book Description

It has been common for both scientists and policy makers to view sanitary provision as a dichotomy between a centralised and a decentralised approach. Moreover, sustainability assessment has also been characterized by a dualistic approach, between the techno-centric and the eco-centric. Such views are often simplistic and not in tandem with the existing multiple sanitary options and service providers in East African cities, which defy such classification. This book provides the theoretical and empirical basis for a third way of classifying and assessing the multiple technical and institutional options to sanitary provision. This novel assessment approach called 'modernised mixtures' is used in this book as a tool for conceptualising, assessing and improving sanitary provision in East African cities. The assessment is based on four social and technical dimensions and three sustainability criteria. This inclusive approach in assessing sanitary mixtures, benefits decision making among imperfect options.

Post Treatments of Anaerobically Treated Effluents


Book Description

The anaerobic process is considered to be a sustainable technology for organic waste treatment mainly due to its lower energy consumption and production of residual solids coupled with the prospect of energy recovery from the biogas generated. However, the anaerobic process cannot be seen as providing the ‘complete’ solution as its treated effluents would typically not meet the desired discharge limits in terms of residual carbon, nutrients and pathogens. This has given impetus to subsequent post treatment in order to meet the environmental legislations and protect the receiving water bodies and environment. This book discusses anaerobic treatment from the perspective of organic wastes and wastewaters (municipal and industrial) followed by various post-treatment options for anaerobic effluent polishing and resource recovery. Coverage will also be from the perspective of future trends and thoughts on anaerobic technologies being able to support meeting the increasingly stringent disposal standards. The resource recovery angle is particularly interesting as this can arguably help achieve the circular economy. It is intended the information can be used to identify appropriate solutions for anaerobic effluent treatment and possible alternative approaches to the commonly applied post-treatment techniques. The succeeding discussion is intended to lead on to identification of opportunities for further research and development. This book can be used as a standard reference book and textbook in universities for Master and Doctoral students. The academic community relevant to the subject, namely faculty, researchers, scientists, and practicing engineers, will find the book both informative and as a useful source of successful case studies.




Biomass Wastes for Sustainable Industrial Applications


Book Description

In this edited volume, Verma and Dubey collate important discussions from international researchers to address major innovations in the sustainable industrial applications of biomass wastes, including processing fundamentals, extraction, purification, properties, and industrial applications. The amount of biomass waste is rising quickly, and such waste offers numerous advantages for sustainable development, particularly for environmentally friendly industrial use. This book therefore addresses this situation by providing a comprehensive overview of the sustainable industrial uses of biomass wastes. To enable ease of use and to facilitate readers’ ability to implement this information in real-world contexts, the book is divided into three sections. First, the introduction discusses biomass wastes and their classification, processing, sustainability, and more as well as the production of bioproducts. The second part addresses classification in more detail in contexts, including forestry, agriculture, animal, industrial, municipal, and food processing wastes. Last, the third section addresses applications in areas such as electricity generation; lubrication, adhesion, and anticorrosion; green energy storage; catalysis; and more. Through this approach, readers will gain a comprehensive understanding of the challenges and opportunities of biomass wastes and will be able to apply their knowledge in a range of contexts, whether in further research or in industrial and other real-world scenarios. This book is a vital resource for a broad readership, including students, academics, research professionals, research enterprises, R&D, and defence research laboratories. Especially, those researching and working in fields such as chemical engineering, material science and engineering, nanotechnology, energy, and environmental engineering will benefit greatly from the discussions within.
