Theory and practice of biological wastewater treatment

The analysis of numerous compounds having carcinogenic or toxic properties is described, with references given to their properties as determined by biological test procedures. The identification in surface waters discharged from industrial processes is recorded. With the growing interest in the reuse of treated effluents for potable and other uses it is important to monitor the composition of effluents, receiving waters and reclaimed water. Descriptions of systems for identifying groups of compounds in such waters and determining specific chemicals by manual automated and computerized techniques, a combination of microwave plasma detection and gas chromatography is given for the quantitative determination of micropollutants in water as well as the use of uV spectral analysis for such purposes. Applications of the use of ion-exchange materials in analysis, ion selective electrodes for continuous analysis, the determination of fluoride, cadmium, copper and mercury, the use of chemiluminescence in analysis, the examination of sediments and the size analysis of particles are the subject of separate papers. The book contains an enormous amount of information, especially on the analysis of hazardous or potentially hazardous organic compounds present in low concentration and for this reason the individual articles and the numerous literature references make it a valuable source book. Unfortunately, many of the compounds referred to in the text are not listed in the index. This would have greatly increased the editorial work but would have added t o t h e v a l u e o f t h e book as a work o f r e f e r e n c e . A n a l y s t s , r e s e a r c h w o r k e r s and t h o s e involved in setting enviromnental standards will find the book of use. S.H.JENKINS

D.L.Ford describes the process of oxygen transfer and the equipment used for the purpose, adding a useful appendix on the determination of the alpha factor. In a chapter on aerated lagoons C.E.Adams gives the principles of the process and helpful detail on their design under varying temperature conditions. The subject of the use of dispersed flow models is introduced by S.J.Arcievala and illustrated by reference to activated sludge treatment, aerated lagoons and stabilization ponds. The account of aerobic digestion by Eckenfelder and Adams is well illustrated by a worked out example. This also applied to D.F.Ford and L.F.Tischler's contribution of pond treatment of industrial wastewaters. Anaerobic digestion is dealt with in principle and theory by A.L.Downing and A.D.K.Kell and by W.E.Eckenfelder. Downing and Kell also contribute a chapter on advanced biological treatment and Arcievala follows this with the reuse of effluent. Modelling in biological treatment and the economics of such processes are described by l.l.Esen and K.R.Imhoff respectively. Imhoff also provides a detailed account of instream aeration and river basin management. Modelling for outfall design is discussed b y G.J.Balafontas and T.S.Xanthoponlos The design principles referred to in the book are profusely illustrated by worked out examples, the answers to which are given in a separate section. This is an excellent manual for teaching in class and for self-teaching. Process design engineers will also find it useful. Its only short coming is that the subject of pilot plant experimentation, which is too important to be ignored because of the variability of the conditions under which wastewaters have to be treated, receives scant attention.
