Book excerpt: En France, environ 15 millions de personnes sont concernées par l’assainissement autonome et chaque année, plus de 100 000 installations sont mises en place. Ces procédés se composent classiquement d’un prétraitement anaérobie réalisé par une fosse toutes eaux qui est suivi d'un traitement par infiltration dans le sol. Ce traitement met à profit le pouvoir épurateur des sols qui est principalement lié à la présence des micro-organismes. Le développement d'un biofilm dans les systèmes de traitements est fréquemment évoqué pour sa contribution à l’élimination des diverses pollutions ou encore pour sa participation au colmatage des massifs. L'objectif du travail de la thèse a consisté à comprendre et à représenter la dynamique du biofilm dans ses composantes favorables et défavorables au sein de systèmes filtrants utilisés en assainissement non collectif. Pour cela, 4 réacteurs expérimentaux de 0,3016 m3 de sol ont été conçus en respectant le plus possible les consignes décrites dans la norme XP P 16-603 relative à l'assainissement autonome. Ils ont été garnis d’une part d’un sol naturel (limon sablo-argileux) et d’autre part d’un sol sableux. Ils ont été alimentés en effluent septique à une charge nominale et à une surcharge ; 5 et 12 cm/j durant 416 jours pour les réacteurs de sable et 2 et 5 cm/j 246 jours pour les réacteurs de limon. Des études du comportement épuratoire et de l'hydrodynamique ont été réalisées à travers la détermination des rendements d'élimination et de l'évolution des temps de séjour. Parallèlement, le développement de biofilm à différentes profondeurs des massifs a été observé. La variation temporelle de la structure de la communauté bactérienne a été approchée par des empreintes métaboliques et génétiques. Les performances épuratoires et le comportement hydrodynamique obtenus sur les réacteurs garnis de sable ont été stables et en adéquation avec les données bibliographiques ce qui a permis de valider ces dispositifs expérimentaux pour des études d'assainissement autonome. En revanche, un des réacteurs garnis avec un limon sablo-argileux a présenté des dysfonctionnements. La mise en œuvre d'un sol naturel, très hétérogène reste délicate. Le développement du biofilm dans les massifs de sable a été observé essentiellement dans les premiers centimètres du massif filtrant et l'épaisseur (profondeur) de cette zone a été fonction de la charge. L'augmentation de la quantité de biofilm n'a pas eu d'impact significatif sur les performances épuratoires pendant la durée de l'étude. Quant à la participation du développement biofilm, elle ne semble pas prépondérante contrairement à l'accumulation de matière. Aussi, un modèle simplissime d'accumulation de matière a été proposé. Des empreintes métaboliques et moléculaires des communautés bactériennes ont montré le rôle "tampon" des massifs dans l'élimination des bactéries des systèmes de traitements. Aussi, il a été montré que les protozoaires participeraient à ce processus de façon importante.

Book excerpt: Infiltration systems are water treatment technologies where water vertically percolates through porous media while several biogeochemical processes occur. Biofilms are the main responsible for those biogeochemical processes due to their ability to colonize sediments as well as due to their role in transformation of organic matter and nutrients in aquatic ecosystems and subsurface environments. However, an excessive biofilm growth in sand filtration systems can significantly reduce their infiltration capacity (bio-clogging), thus constraining the processes that occur therein. Sediment grain size distribution influences the performance of these systems since it determines hydrological characteristics in subsurface sediments influencing biofilm growth as well as the process rates of biogeochemical processes in depth. Furthermore, sediment grain size can also influence the occurrence and depth-extension of bio-clogging. The main objective of this doctoral thesis is to study the influence of grain size distributions on biogeochemical processes and on bio-clogging in depth in sand infiltration systems used as potential tertiary treatments for the removal of organic matter and nutrients in water. To achieve this objective, two infiltration experiments have been carried out: (a) a laboratory-scale columns experiment using 5 sediment grain size distributions used as potential infiltration systems (Chapter I) and (b) an outdoor infiltration experiment in sediment tanks using two sediment grain size distributions (Chapter II and Chapter III). The results of this thesis show how sediment grain size distribution influences biofilm establishment and growth, biogeochemical rates as well as occurrence of bio-clogging in surface sediments and in depth. Accordingly, coarse sediments (coarse system) allow higher biomass in depth but they do not have the ability to remove dissolved phosphorous; however, due to high input loads they showed higher process rates. Grain size distribution of coarse sediment in the upper layer and fine sediment in the bottom layer (coarse-fine system) promotes the accumulation of biomass at the interface of the two sediment layers which results in a hot-spot of microbial activity. In addition, it promotes nutrient accumulation in sediments (dissolved phosphorous removal) possibly due to the fact that its flow velocities are smaller than those of a coarse system and therefore the contact time between the water and sediment increases by promoting the assimilation and adsorption of nutrients in the porous medium. Biomass establishment in fine sediments (fine system) results in greater bio-clogging due to lower initial porosity compared to systems with coarse sediment on the surface. This lower porosity results in less space available to colonize, and due to this, biofilm in the top layer of the monolayer fine system could reach the maturity state earlier than the bilayer coarse-fine system. That, together with the lower flows in the fine system, favours the detachment of biofilm in the top layer and its transport in depth. EPS accumulation in depth (due to live bacteria release or due to transport from upper sediment layers) is the main factor causing K variations in depth (potential to cause deep-clogging). Results also showed that mixed sediments of fine and coarse sands (mixture system) and the fine-coarse system achieve similar performance than fine system reaching similar biomasses between them and lower process rates than the other grain size distributions studied.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-18 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

Book excerpt: In the late 1970s and early 1980s, our nation began to grapple with the legacy of past disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive Envir- mental Response, Compensation, and Liability Act (CERCLA), commonly known as Sup- fund, it became the law of the land to remediate these sites. The U. S. Department of Defense (DoD), the nation’s largest industrial organization, also recognized that it too had a legacy of contaminated sites. Historic operations at Army, Navy, Air Force, and Marine Corps facilities, ranges, manufacturing sites, shipyards, and depots had resulted in widespread contamination of soil, groundwater, and sediment. While Superfund began in 1980 to focus on remediation of heavily contaminated sites largely abandoned or neglected by the private sector, the DoD had already initiated its Installation Restoration Program in the mid-1970s. In 1984, the DoD began the Defense Environmental Restoration Program (DERP) for contaminated site assessment and remediation. Two years later, the U. S. Congress codified the DERP and directed the Secretary of Defense to carry out a concurrent program of research, development, and demonstration of innovative remediation technologies. As chronicled in the 1994 National Research Council report, “Ranking Hazardous-Waste Sites for Remedial Action,” our early estimates on the cost and suitability of existing techn- ogies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

Book excerpt: Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.
