DOWNLOAD EBOOKWater is the most basic need of mankind. Drinking water is considered the most essential use of water in life. Therefore it must be free of pathogens, toxins and carcinogens. Absolutley pure water does not exist in nature. Surface water absorbs particles, carbon dioxide and other gases and mixes with silt and inorganic matters from the environment. When treated and untreated domestic and industrial waste is discharged into natural bodies of water the situation becomes even more complex. Thus human waste, drinking water and communicable diseases are directly related. Water contamination is measured by the level of pollutants present in a sample. Regular analytical estimation of wastewater is the answer. This manual emphasizes the importance of water purity for drinking and domestic purposes, different types of water and their utilization in various activities, the water quality requirements and criteria of International and Governmental Agencies, and simple estimation procedures and the significance of each analytical test. Quality Assessment of Water and Wastewater describes methods for ascertaining the quality and contamination levels of waters from a range of sources like ground, surface, potable water supplies, marine, beaches, swimming pools and other recreational facilities, and domestic and industrial wastewater. It includes important derivatives used in the preparation of standard solutions, data analysis, interpretation and units of expressions of the results. It also discusses all major pollutants - their origins and impact on the environment and health - with the basic chemistry of their analysis and complete methodology explained systematically.

DOWNLOAD EBOOKA thorough analysis of public policy and the Clean Water Act'seffect on water quality in the U.S. Using water quality data and historical records from the past 60years, this book presents the measured impact of the 1972 CleanWater Act on domestic waterways-ecologically, politically, andeconomically. Municipal Wastewater Treatment supports thehypothesis that the Act's regulation of wastewater treatmentprocesses at publicly owned treatment works (POTW) and industrialfacilities has achieved significant success. The authors' case ispresented in: * Background information on the history of water pollution controland water quality management * Chapters addressing long-term trends in biochemical oxygen demandloadings from municipal wastewater plants and the "worst-case"dissolved oxygen levels in waterways downstream of point sourcesbefore and after the Clean Water Act * Nine case study assessments of long-term trends of pollutantloading water quality and environmental resources associated withPOTW discharges Using long-term trends in dissolved oxygen as the key indicator ofwater quality improvements, this book provides a detailedretrospective analysis of the effectiveness of the water pollutioncontrol policies and regulations of the 1972 Clean Water Act. Thesuccesses of the Act that have been achieved over the past 30 yearsare placed in the historical context of the "Great SanitaryAwakening" of the 19th century and changes in public policies forwater supply and water pollution control that have evolved duringthe 20th century to protect public health and the intrinsic valueof aquatic resources. Case study sites include the ConnecticutRiver, Hudson-Raritan Estuary, Delaware Estuary, Potomac Estuary,Upper Chattahoochee River, Ohio River, Upper Mississippi River, andWillamette River. Complete with end-of-chapter summaries and conclusions, MunicipalWastewater Treatment: Evaluating Improvements in National WaterQuality is an essential book for engineers, scientists, regulators,and consultants involved in water quality management and wastewatertreatment, as well as students of environmental engineering,environmental science, and public policy.

DOWNLOAD EBOOKHigh-Risk Pollutants in Wastewater presents the basic knowledge regarding the diversity, concentrations, and health and environmental impacts of HRPs in municipal wastewater. The book summarizes information on the types (e.g. heavy metals, toxic organics and pathogens) and toxicities of HRPs in wastewater. In addition, it describes ecological and health hazards arising from the living things’ direct/indirect contacts with the HRPs during their full lifecycles (generation, disposal, discharge and reuse) in wastewater or water environments. Sections cover the concepts of appropriate technology for HRP hazard/risk assessment and wastewater treatment/reuse and the issues of strategy and policy for increasing risk control coverage. Finally, the book focuses on the resolution of water quality monitoring, wastewater treatment and disposal problems in both developed and developing countries. Presents information on HRPs and their risk assessment and control technologies Provides basic knowledge regarding the diversity, concentrations, and health and environmental impacts of HRPs in municipal wastewater Summarizes information on the types (e.g. heavy metals, toxic organics and pathogens) and toxicities of HRPs in wastewater

DOWNLOAD EBOOKIn this compilation, the authors open with an address of alternative advanced technologies that effectively meet the desired level of removal of recalcitrant contaminants from water. They discuss the advantages and disadvantages of different state of the art technologies, assess the need for further development, as well as estimate the potential for large scale applications based on technological advancement and availability. Next, the book delves into the origin of chitin, which can be traced back to 1811 when it was first discovered in mushrooms by Henri Braconnot while he was Professor of Natural History and Director of the Botanical Gardens at the Academy of Science in France. Twenty years later, chitin was isolated in insects. In 1878, Ledderhose determined that chitin was constructed of glucosamine and acetic acid. The subsequent chapter presents results of an experiment analyzing the concentration of dissolved substances as a major factor that determines the efficiency of membrane separation for wastewater treatment. The results show that selectivity of different types of semi-permeable membranes in a wide range of concentrations can be predicted with sufficient accuracy. Another paper deals with aerobic treatment, i.e. the activated sludge method and the anaerobic process. Activated sludge is the most widely used method to bring about stabilization in wastewater having organic matter constituents. The possibilities of function are analysed in this sludge system, and a short outline is given about the humans plans in the future with connection of the biological waste water treatment. The closing paper discusses the treatment of wastewater from surfactants, as its application has increased markedly both in everyday life and in many industrial branches. Water containing surfactants is fatal for the environment and has a toxic impact on the human body, causing cancerogenic, mutagenic and allergenic effects. Thus, there is a great need for reliable water treatment in chemically developed countries.

DOWNLOAD EBOOKClean water is one of the most important natural resources on earth. Wastewater, which is spent water, is also a valuable natural resource. However, wastewater may contain many contaminants and cannot be released back into the environment until the contaminants are removed. Untreated wastewater and inadequately treated wastewater may have a detrimental effect on the environment and has a harmful effect on human health. Water quality engineering addresses the sources, transport and treatment of chemical and microbiological contaminants that affect water. Objectives for the treatment of wastewater are that the treated wastewater can meet national effluent standards for the protection of the environment and the protection of public health. This book, which is based on the Special Issue, includes contributions on advanced technologies applied to the treatment of municipal and industrial wastewater and sludge. The book deals with recent advances in municipal wastewater, industrial wastewater, and sludge treatment technologies, health effects of municipal wastewater, risk management, energy efficient wastewater treatment, water sustainability, water reuse and resource recovery.
