Publisher's Synopsis
The activated sludge process is widely used for treating wastewater. Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. It is also a valuable educational and training package for universities and post experience courses.
The CD-ROM provides detailed explanations and practical applications which are profusely illustrated by 75 minutes of audio commentary, almost 100 video sequences and about 650 photographs as well as animations. The CD-ROM is comprised of four modules: The module Process Control starts with an explanation of the basic principles of the activated sludge process. Then, the effect of the process conditions on the composition of the biomass is demonstrated. In Trouble Shooting major operational problems are discussed and solutions are presented. In Sludge Investigation the methods used for microscopic sludge investigation are demonstrated in detail. In the Encyclopaedia all key terms are defined and explained in detail. The Demo module provides an introductory demonstration of the activated sludge process.
