Coagulation and Flocculation in Water and Wastewater Treatment


Book Description

Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated since the 1st Edition it has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. A thorough gamut of treatment scenarios is attempted, including turbidity, color and organics removal, including the technical aspects of enhanced coagulation. The effects of temperature and ionic content are described as well as the removal of specific substances such as arsenic and phosphorus. Chemical phosphorus removal is dealt with in detail, Rapid mixing for efficient coagulant utilization, and flocculation are dealt with in specific chapters. Water treatment plant waste sludge disposal is dealt with in considerable detail, in an Appendix devoted to this subject. Invaluble for water scientists, engineers and students of this field, Coagulation and Flocculation in Water and Wastewater Treatment is a convenient reference handbook in the form of numerous examples and appended information.










Basic Water and Wastewater Treatment


Book Description

Basic Water and Wastewater Treatment discusses the water cycle, flow measurement, physical treatment processes, chemical treatment processes, biological treatment process, and sludge handling and treatment. The book also describes the use of the BASIC computer program to calculate problems involving water pollutants. Flow measurements involve the use of a gauging structure, velocity measurements of a known cross-section, or dilution gauging. To evaluate, in quantitative terms, the effects of a certain pollutant discharged and received by a body of water, the investigator can employ a tool in chemical dilution gauging—the mass balance analysis. Many microorganisms, organic and inorganic compounds degrade in a natural process of self-purification; their decay can be modeled as an exponential function. One standard of water treatment facility or wastewater treatment plant cannot be built to deal with all the various components of water pollution. The book cites relevant standards such as the EC Directive 80/778/EEC: "Quality of Water Intended for Human Consumption" in the EU; the "Safe Drinking Water Act" in the U.S.A.; and the "Guidelines for Drinking Water Quality" issued by the World Health Organization. The book describes water quality parameters, water supply sources, and wastewater collection, including its treatment and disposal.
