This course is for operators, technicians, engineers and managers of aerated stabilization basins. Biological treatment concepts for ASBs will be reviewed. Effluent treatment plant microbiology (filamentous and non-filamentous) will be related to ASB performance. Management and operation of the key control elements for ASBs will be discussed.
It is operations oriented providing practical information for day-to-day operation. Attendees will participate presenting their operational approaches to various topics such as nutrients, aeration and basin sludge removal.
· Composition of Wastewater - types of solids, organics
· Preliminary Treatment - screening, equalization
· Primary Treatment - settleable solids vs. suspended solids removal
· Secondary Treatment - conversion of organics, solids capture
· Solids Capture and Efficiency
· Negative Impacts from Priamry on Secondary
·Overview of ASB Processes
· Bacterial growth - metabolism, respiration, growth phases
· Growth Pressures: Temp., pH, dissolved oxygen, nutrients, toxics, hydraulic loading
· Floc Structure
· Filament Abundance
· Protozoa and Other higher Life Forms
· Types of Aeration
· Monitoring, D.O. probes
· Mixing
· Causes of D.O. deficiency
