Management of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focused on the development of an innovative sludge treatment unit that is based on the microwave irradiation technology. The technology provides a rapid and efficient option for sludge treatment in isolated conditions such as slum, emergency, and similar situations. The microwave based technology forms part of the eSOS (emergency sanitation operation system) concept that promotes an integrated sanitation approach in which all components of the entire sanitation chain are planned holistically. Besides, the study addresses the deficiencies associated with the poor choice of emergency sanitation technology options by proposing a methodology that is based on compensatory multi-criteria analysis. This study contributes in providing solutions towards improved sanitation in complex scenarios, especially the management of faecal sludge in emergency and slum conditions.

Recently, research efforts aiming to improve energy efficiency of wastewater treatment processes for large centralized wastewater treatment plants (WWTPs) have been increasing. Global warming impacts, energy sustainability, and biosolids generation are among several key drivers towards the establishment of energy-efficient WWTPs. WWTPs have been recognized as major contributors of greenhouse gas emissions as these are significant energy consumers in the industrialized world. The quantity of biosolids or excess waste activated sludge produced by WWTP will increase in the future due to population growth and this pose environmental concerns and solid waste disposal issues. Due to limited capacity of landfill sites, more stringent environmental legislation, and air pollution from incineration sites, there is a need to rethink the conventional way of dealing with wastewater and the sludge production that comes with it. This book provides an overview of advanced biological, physical and chemical treatment with the aim of reducing the volume of sewage sludge. Provides a comprehensive list of processes aiming at reducing the volume of sewage sludge and increasing biogas production from waste activated sludge. Includes clear process flowsheet showing how the process is modified compared to the conventional waste activated sludge process. Provides current technologies applied on full scale plant as well as methods still under investigation at laboratory scale. Offers data from pilot scale experience of these processes

Efficient particle separation in order to meet stringent regulatory standards represent one of the biggest challenges facing the process industry operators today. Emerging environmental problems such as climate change, population growth and natural resource depletion make it more compelling to undertake research into alternative phase separation techniques and optimization of existing ones. Meeting this challenge requires innovative, revolutionary and integrated approach in the design and optimization of various unit processes in fine particle separation. Flocculation is widely used as an effective phase separation technique across many process industries such as water and wastewater treatment and in minerals processing. In this work, a new pre-treatment technique was developed using a patented bench scale reactor unit as a technical proof of concept. Furthermore, the book provides a valuable insight into the hydrodynamics and fluid-particle interactions within the agglomeration units.The relatively high solids content of the stable pellets (approximately 30%) and very low residual turbidity of the post-sedimentation supernatant (7 NTU) clearly demonstrate the potential of this technique. In addition to significantly improving the subsequent solid-liquid separation efficiency, this study also showed that the effluent can be recycled back into the sewer network or utilized for non-portable reuse. The findings obtained from this research will be extremely useful in the scaling up and optimization of the reactor system.

Este livro destina-se a engenheiros e técnicos responsáveis por projetos e operação de estações de tratamento de água e tem o intento de ser uma fonte de informação prática - mais do que teórica - no tema de tratamento e disposição dos resíduos de uma estação de tratamento de água. A respeito, o professor Francisco Gross comenta:'Esta nova obra do engenheiro Carlos Richter constitui um excelente documento, de grande valor didático, onde se encara a temática do tratamento e disposição final dos lodos gerados em estações de água potável de forma rigorosa e prática. De fato, em virtude da notável experiência e formação do autor, se logra conjugar no livro aspectos teóricos vinculados à modelação dos distintos fenômenos analisados, assim como antecedentes práticos de operações reais realizadas com esta temática tão particular.'
