This project was carried out to assess the impact of the use of oxygen and oxygen-enriched air for aeration of activated sludge systems on the safety of municipal waste-water treatment plants and their personnel. The tasks included (1) determination of oxygen combustion hazards from desk top analyses and small scale flammability tests, (2) characterization and safety evaluation of oxygen aeration activated sludge systems from field visits and literature, (3) development of safety strategy and economics, and (4) preparation of standard safety manual and safety checklists for wastewater treatment with oxygen aeration.
