Description: This presentation will describe the various types of aerobic treatments units (ATU) along with the similarities and differences among the various types. The treatment process used in ATU where microbes transform solids into gases, cell mass and non-degradable material will be covered. An overview of the operation and maintenance checklist for ATU will be covered, but troubleshooting of effluent problems with surface discharging systems, particularly ammonia. The settleability test for determining sludge wasting will be covered.
Learning Objectives: Understand the flow layout for suspended growth and attached growth ATUs; understand the treatment principles employed in the ATU technologies; and review the operation and maintenance checklist. Identify solutions for hard to treat waste, foaming, abnormal levels of DO, poor settling characteristics and other ATU trouble points.
