Wastewater Technology Fact Sheet: Oxidation Ditches
were collected from 17 oxidation ditch plants. The average design flow for these plants varied between 378 to 45,425 3/daym ( to 12 MGD). The average performance of these plants, summarized in Table 1, indicates that oxidation ditches achieve BOD, suspended solids, and ammonia nitrogen removal of greater than 90 percent. Likewise,
