Abstract

"It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering."

Abstract

"Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. &#xD;&#xD;Biological Wastewater Treatment addresses this deficiency. &#xD;&#xD;It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. &#xD;The book forms part of an internet-based curriculum in biological wastewater treatment which also includes&#xD;o summarized lecture handouts of the topics covered in book&#xD;o filmed lectures by the author professors&#xD;o tutorial exercises for students self-learning &#xD;Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence."&#xD;

Abstract

The use of trace elements to promote biogas production features prominently on the agenda for many biogas-producing companies. However, the application of the technique is often characterized by trial-and-error methodology due to the ambiguous and scarce basic knowledge on the impact of trace elements in anaerobic biotechnologies under different process conditions. This book describes and defines the broad landscape in the research area of trace elements in anaerobic biotechnologies, from the level of advanced chemistry and single microbial cells, through to engineering and bioreactor technology and to the fate of trace elements in the environment. The book results from the EU COST Action on ‘The ecological roles of trace metals in anaerobic biotechnologies’. Trace elements in anaerobic biotechnologies is a critical, exceptionally complex and technical challenge. The challenging chemistry underpinning the availability of trace elements for biological uptake is very poorly understood, despite the importance of trace elements for successful anaerobic operations across the bioeconomy. This book discusses and places a common understanding of this challenge, with a strong focus on technological tools and solutions. The group of contributors brings together chemists with engineers, biologists, environmental scientists and mathematical modellers, as well as industry representatives, to show an up-to-date vision of the fate of trace elements on anaerobic biotechnologies.&#xD;

Abstract

The FISH Handbook for Biological Wastewater Treatment provides all the required information for the user to be able to identify and quantify important microorganisms in activated sludge and biofilms by using fluorescence in situ hybridization (FISH) and epifluorescence microscopy. It has for some years been clear that most microorganisms in biological wastewater systems cannot be reliably identified and quantified by conventional microscopy or by traditional culture-dependent methods such as plate counts. Therefore, molecular biological methods are vital and must be introduced instead of, or in addition to, conventional methods. At present, FISH is the most widely used and best tested of these methods. This handbook presents all relevant information from the literature and, based on the extensive experience of the authors, advice and recommendations are given for reliable FISH identification and quantification.

Abstract

Biofouling of Spiral Wound Membrane Systems gives a complete and comprehensive overview of all aspects of biofouling, bridging the gap between microbiology, hydraulics and membrane technology. High quality drinking water can be produced with membrane filtration processes like reverse osmosis (RO) and nanofiltration (NF). As the global demand for fresh clean water is increasing, these membrane technologies are increasingly important. Most past and present methods to control biofouling have not been very successful. An overview of several potential complementary approaches to solve biofouling is given and an integrated approach for biofouling control is proposed.

Abstract

In many countries, especially in developing countries, many people lack access to water and sanitation services and this inadequate service is the main cause of diseases in these countries. Application of appropriate wastewater treatment technologies, which are effective, low cost, simple to operate, proven technologies, is a key component in any strategy aimed at increasing the coverage of wastewater treatment. Sustainable Treatment and Reuse of Municipal Wastewater presents the concepts of appropriate technology for wastewater treatment and the issues of strategy and policy for increasing wastewater treatment coverage. The book focuses on the resolution of wastewater treatment and disposal problems in developing countries, however the concepts presented are valid and applicable anywhere and plants based on combined unit processes of appropriate technology can also be used in developed countries and provide to them the benefits described.

Abstract

"The Third African Sanitation and Hygiene Conference was held in Kigali, Rwanda in July 2011. It was hosted by the Government of the Republic of Rwanda, and the African Minister s Council on Water. The meeting attracted extraordinary interest: over 1000 people registered and nearly 900 people attended from a total of 67 countries, including representatives of 42 African countries. The content of AfricaSan 3 was aligned with the needs of countries as defined in country preparation meetings which took place in advance. AfricaSan 3 looked to address the country needs and to commitments and country action planning. Different groups (ministers, civil society, local government, utilities, and donors) committed to actions to support the goals of AfricaSan. The goal of the AfricaSan process is to support countries to achieve the Millennium Development Goal, (MDG) for sanitation and hygiene. &#xD;&#xD;Sanitation and Hygiene in Africa: Where do We Stand? takes stock of progress made by African countries through the AfricaSan process since 2008 and the progress needed to meet the MDG on sanitation by 2015 and beyond. This book addresses priorities which have been identified by African countries as the key elements which need to be addressed in order to accelerate progress. &#xD;&#xD;-- Reviews progress on implementing the eThekwini Declaration to meet the MDG for sanitation and progress generally in Africa. It analyses what is needed to accelerate the rate of access to sanitation in Africa. &#xD;-- Shares advances in the evidence base on sanitation and hygiene in Africa to be able to assist decision-makers to overcome key blockages in implementing large-scale sanitation and hygiene programs. &#xD;-- Raises the profile of sanitation and hygiene as a determinant of sustainable development in order to strengthen leadership and advocacy for sustained sanitation and behavior changes. &#xD;&#xD;This book is essential reading for government staff from Ministries responsible for sanitation, sector stakeholders working in NGOs, CSOs and agencies with a focus on sanitation and hygiene and water and sanitation specialists. It is also suitable for Masters courses in water and sanitation and for researchers and the donor community."
