The Microlife: Filamentous Organisms reviews the significant organisms that inhabit the activated sludge process and the positive and negative roles they perform in the degradation and removal of wastes. It presents the operational factors that promote or control the growth of these organisms and reviews the foam-producing filamentous organisms, and sludge-bulking filamentous organisms. This course covers filamentous organism and floc development, filamentous organism control measures, and filamentous organism identification. The review of control measures includes the use of anaerobic, anoxic, F?M, and feast-and-famine selectors.

Troubleshooting the Sequencing Batch Reactor presents a description and history of the batch feed system for the treatment of wastewater. The description includes a biological review of each phase (fill, react, settle, decant, and idle), phase time, and adjustments in phase times in the SBR along with the occurrence of oxic, anoxic, and anaerobic conditions. Process control measures (conductivity, F/M, target DO, microscopic evaluationm target nutrient (nitrogen and phosphorus) values, MLSS, ORP, OUR, Sludge Age, SOUR, and SVI), sampling techniques (influent, react, and effluent), and troubleshooting charts are reviewed. An examination of biological and chemical nutrient (nitrogen and phosphorus) removal measures, including the use of endogenous decay of bacteria for denitrification, is presented. Cold climate adjustment are addressed for the successful operation of the SBR during depressed wastewater temperatures.

BOD and Metabolism

BOD and Metabolism is an introduction to the different substrates or foods (carbonaceous BOD and nitrogenous BOD) discharged to treatment processes, the bacteria (aerobic facultative and anaerobic) that degrade (metabolize) the substrates, and the aerobic anoxic and anaerobic environments where bacterial degradation of substrates occurs. Operational factors affecting metabolism and bacterial growth -- e.g., pH, temperature, and enzymes (including folicnacid) are presented, and the bacterial growth curve and resulting sludge age of the biomass are correlated with operational conditions. The course troubleshoots BOD testing and compares BOD testing and mixed liquor tank DO requirements. It also addresses the use of specific oxygen uptake rate (SOUR).

Troubleshooting the Activated Sludge Process with a Microscope

Troubleshooting the Activated Sludge Process with a Microscope provides the rationale for use of the microscope for process control and troubleshooting of the activated sludge process. Schematics and work sheets are used with 35mm slides to illustrate acceptable ("healthy") and unacceptable mixed liquor conditions. Components of a microscopic examination of mixed liquor that are illustrated include fine solids, floc particles, filamentous organisms, protozoa, metazoa, and foam. The course also reviews sampling, storage of samples, recommendations for microscopes and photomicroscopy, and laboratory exercises. Please note: Wastewater samples and the microscope itself are not used in this course.
