The research project was undertaken with the overall objective of better defining the oxygen-transfer performance, operation and maintenance (O and M) requirements, and proper design approaches for ceramic fine-bubble dome and disc-diffuser aeration systems used in activated-sludge waste-water treatment. A study of dome and disc-diffuser aeration systems in 19 North American activated-sludge plants was carried out during the project. All were municipal waste-water treatment plants treating predominantly domestic wastes, though some had significant industrial flows as well. Data on design bases, influent and effluent wastewater characteristics, aeration power and air flow, and O and M experience were requested from each plant. These were supplemented as needed by on-site investigations and interviews that focused on the practical operating experience of plant personnel.
