Water supply alone is a big issue, but so is the equally important aspect of water quality. Our water resources are difficult to manage because they come from a multitude of locations where a tremendous number of contaminants, often from human activities, are degrading these resources. Water quality objectives and the chemical, physical and biological processes are necessary for designing and managing modern drinking water and wastewater treatment plants. The principles of coagulation, flocculation, sedimentation, filtration, biological treatment, solids handling, disinfection and advanced treatment processes are present.
Principles of Water and Wastewater Treatment is the boo based on Water and Wastewater Process Technologies. The book outlines the principle unit operations that are involved in the separation, degradation and utilization of organic and inorganic matter during water and wastewater treatment. The book detailed on the subjects of chemistry, biology and engineering covered in Process Science and Engineering for Water and Wastewater Treatment and provides a descriptive introduction to unit operations that are further described with design and operational techniques. In this book, the material has been extensively updated and revised in response to regulatory requirements and growing public awareness, particularly in the areas of disinfection, membrane filtration, disposal of treatment plant residuals, and basic microbiology with an emphasis on human pathogens and diseases.
