Use of concrete tanks may be preferable for larger sizes (Sloan, 1999). Extended aeration plants are usually started up using "seed sludge" from another sewage plant. It may take as many as two to four weeks from the time it is seeded for the plant to stabilize (Sloan, 1999). Sequencing batch reactors A sequencing batch reactor (SBR) is a
