Chemistry of Effluent Treatment. 148 pages - £14.OO
Ed. George Kakabadse,
Applied Science Pub.
This book consists essentially of the eleven papers given at a symposium in 1978. The legal requirements in the UK for discharges of industrial effluents into sewers, rivers and tidal waters are described, followed by considerations of the pros and cons of treatment of effluents by manufacturers of disposal by discharge to a public sewer. The treatment of effluetns by chemical or biological methods are compared. To produce effluents better than those obtained by conventional treatment processes, tertiary treatment is required and the tertiary treatment processes available are described in two chapters, one of which includes an account of ion exchange, carbon adsorption and flocculation processes. One type of effluent is dealt with specifically: this is the class of effluent containing metals. Processes for recovering these are described so as to save metal and obtain re-usable process water. An account is also given of the promising results obtained to produce livestock feeds from sewage sludge. Instrumentation and on line process and monitoring are the subjects of the final chapters. The subjects are well presented in concise terms understandable to the representatives of industry and water authorities attending the symposium. What seems to be missing is a good account of the enormous variety of industrial effluents produced in the area where the symposium was held, their chemical composition and how they respond to the various processes described in the book.
