The manual can be used independantly but when used in combination with the CD-ROM, it makes a unique tool for process operators to diagnose and solve operational problems. It is also a valuable educational and training package for universities and post experience courses. Click here for more details about the CD-ROM 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. The manual outlines the theoretical framework, extensively illustrated with full-colour micrographs. Contents Microscopy Microscopic sludge investigation Characteristics of activated sludge flocs Filamentous micro-organisms Protozoa and metazoa Conclusions of microscopic sludge investigation The activated sludge process Operational problems Bulking sludge Scum formation

A practical, hands-on guide to using the microscope to analyze activated sludge in wastewater treatment The microscope provides the wastewater treatment plant operator with a special tool for process control and troubleshooting of the activated sludge process. The operator can "read" the organisms and use them as "bioindicators" to determine if operational conditions are acceptable or not acceptable. Written for plant operators and technicians and avoiding unnecessary technical jargon, Microscopic Examination of the Activated Sludge Process explores and explains: Microscopy, including microscopic measurements and techniques Directions for preparing and applying microbiological stains and immobilizing agents and techniques for preparing wet mounts and smears How to identify various types of organisms, including: floc particles and foam; protozoa; rotifers; worms and worm-like organisms; crustaceans; filamentous organisms; and algae and fungi The collection, evaluation, and presentation of observations This straightforward guide includes figures, tables, worksheets, photomicrographs, and black-and-white drawings of many living, microscopic components of the activated sludge process. It equips plant operators and technicians to monitor, regulate, and troubleshoot the treatment processes and also serves as a valuable resource for research professionals and sanitary engineers in wastewater treatment.

Hailed on first publication as a straightforward, practical, and to-the-point account of wastewater principles, practices, and operations for general readers, students, and wastewater operators in training and for all levels of operators at any level of licensure, Spellman's Standard Handbook for Wastewater Operators, Volumes I, II, and III almost

Instrumentation, Control and Automation of Water and Wastewater Treatment and Transport Systems 1993 comprises a selection of manuscripts on the development of control strategies and their applications and on the status and future directions of Instrumentation, Control, and Automation (ICA) in the water and wastewater industry. The book starts by providing an overview of the status, the constraints and the future prospects for ICA in water and wastewater treatment and transport based on the survey responses of experts from 16 different countries. The text continues by presenting the need for dynamic modeling and simulation software to assist operations staff in developing effective instrumentation control strategies and to provide a training environment for the evaluation of such strategies. The book also covers the critical variables in system success; the use of an enterprise-wide computing that emphasizes the importance of strategic planning, performance measures, and human factors associated with the suggested implementation of applied technology; and the use of part-time unmanned operation at a large wastewater treatment plant. A functional approach based on the utility's water and wastewater functional requirements; the collection system monitoring and control; water distribution and control systems; dynamic modeling and simulation; and process control strategy and development are also considered. This book will be beneficial to biochemists, wastewater technologists, and public health authorities.
