About the book: This book is intended for undergraduate (B.E/B. Tech) students of civil engineering and post graduate (M.E/M.Tech) students of environmental science and engineering, and beginners in design of wastewater treatment plants. Also, it will be useful to the established designers of wastewater treatment plants, decision makers of municipal corporations, field executives and pollution control board authorities. Wastewater treatment is a vast and interdisciplinary subject. Wastewater treatment plants are very complex hydro-technical facilities. The concept of planning and design of waste water treatment plants through concise book should be easily understandable to students, beginners in process and hydraulic design of wastewater treatment plants. Once the concepts are understood and reasonably enough confidence of process and hydraulic design of wastewater treatment process is gained then one can acquire specific details of design from different sources and can handle even planning and design of large capacity wastewater/sewage plants to different site conditions and layouts. The author felt to attempt and write a book-cum-design guide covering theory of the subject which is normally required to write examinations. Much stress is given on process and hydraulic design, treatment plant hydraulics, fundamentals of hydraulics and its application in wastewater treatment plant design, and hydraulic profiling of plants. The basic hydraulic concepts are same whether they are used for design of elements of sewage treatment plant or industrial waste water treatment. A pilot project on design of 125 MLD capacity sewage treatment plant has been exercised in order to integrate the process design, hydraulic concepts, control points in plant and hydraulics of various units/components that must operate compatibly to provide the desired flow profile. The recommendations of various Indian standards and manual on Sewerage and Sewage Treatment of CPHEO under Ministry of Urban Development, New Delhi have been followed. The SI units of measurement are used throughout the book and in design calculations. The book contain about 100 diagrams, tables, photos and three large diagrams of sewage treatment plant’s layout, hydraulic profiling of main flow path and return flow. Book features: · Provides enough subject theory and design of wastewater treatment plants in detail. · Theory and design considerations of Activated Sludge Process(ASP) and its modifications, advanced wastewater biological treatment processes like- Sequencing Batch Reactor(SBR), Moving Bed Bio-film Reactor(MBBR), Rotating Biological Contactor(RBC), Up-flow Anaerobic Sludge Blanket (UASB) process has been covered in detail. · It includes plant siting and layout development, support facilities, basics of hydraulics, plant hydraulics and pump hydraulics in depth which is required for hydraulic design and profiling of wastewater treatment plants. · A complete process and hydraulic design, and hydraulic profiling of 125 MLD sewage treatment plant. · Process design of Sequencing Batch Reactor (SBR) process. · Appendices: Tables and Nomograms, standard sizes of pipes of various materials, gates, pumps, aerators, air blowers, and table of constants required for hydraulic calculations.

An Applied Guide to Water and Effluent Treatment Plant Design is ideal for chemical, civil and environmental engineering students, graduates, and early career water engineers as well as more experienced practitioners who are transferring into the water sector. It brings together the design of process, wastewater, clean water, industrial effluent and sludge treatment plants, looking at the different treatment objectives within each sub-sector, selection and design of physical, chemical and biological treatment processes, and the professional hydraulic design methodologies. This book will show you how to carry out the key steps in the process design of all kinds of water and effluent treatment plants. It provides an essential refresher on the relevant underlying principles of engineering science, fluid mechanics, water chemistry and biology, together with a thorough description of the heuristics and rules of thumb commonly used by experienced practitioners. The water treatment plant designer will also find specific advice on plant layout, aesthetics, economic considerations and related issues such as odor control. The information contained in this book is usually provided on the job by mentors so it will remain a vital resource throughout your career. - Explains how to design water and effluent treatment plants that really work - Accessible introduction to, and overview of, the area that is written from a process engineering perspective - Covers new treatment technologies and the whole process, from treatment plant design, to commissioning

Hydraulic Design and Management of Wastewater Transport Systems is a manual resulting from the research project CAPWAT (CAPacity loss in wasteWATer pressure pipelines), which researched the mechanisms for the creation, stagnation and discharge of gas bubbles in wastewater pressure pipelines. During this six-year research programme, it was recognised that there is no hydraulic manual/guideline that focuses on the entire wastewater pressure pipeline system, the processes it includes, and the interaction between the pressure pipeline and the pumping station. This manual provides a compilation of all the hydraulic knowledge that is necessary for designing a wastewater transport system and to manage it operationally. The wastewater transport system is the link between the collection and treatment of the wastewater and the collection system includes, among others, the gravity flow sewage system from the house (or consumer) and service connection through street and main sewers up to the suction basins. The transport system, for which this manual was written, includes the suction basin, the sewage pumping station and the pressure pipelines. Wastewater transport systems are becoming more complex due to building larger sewage water treatment plants, wastewater being transported over greater distances and increasingly more (and smaller) pipelines connecting to the main sewers. The operation of the pumping stations is largely determined by how the entire system behaves. Insight into this operation is, therefore, crucial for proper design and management. The central point of the design is to create an independent and safe system with the necessary transport capacity at minimum societal costs. Predominantly, the management aspect focuses on guidelines to maintain the design principles regarding capacity and required energy.

Step-by-step procedures for planning, design, construction and operation: * Health and environment * Process improvements * Stormwater and combined sewer control and treatment * Effluent disposal and reuse * Biosolids disposal and reuse * On-site treatment and disposal of small flows * Wastewater treatment plants should be designed so that the effluent standards and reuse objectives, and biosolids regulations can be met with reasonable ease and cost. The design should incorporate flexibility for dealing with seasonal changes, as well as long-term changes in wastewater quality and future regulations. Good planning and design, therefore, must be based on five major steps: characterization of the raw wastewater quality and effluent, pre-design studies to develop alternative processes and selection of final process train, detailed design of the selected alternative, contraction, and operation and maintenance of the completed facility. Engineers, scientists, and financial analysts must utilize principles from a wide range of disciplines: engineering, chemistry, microbiology, geology, architecture, and economics to carry out the responsibilities of designing a wastewater treatment plant. The objective of this book is to present the technical and nontechnical issues that are most commonly addressed in the planning and design reports for wastewater treatment facilities prepared by practicing engineers. Topics discussed include facility planning, process description, process selection logic, mass balance calculations, design calculations, and concepts for equipment sizing. Theory, design, operation and maintenance, trouble shooting, equipment selection and specifications are integrated for each treatment process. Thus delineation of such information for use by students and practicing engineers is the main purpose of this book.
