Biochemical Oxygen Demand

BOD atau Biochemical Oxygen Demand adalah suatu karakteristik yang menunjukkan jumlah oksigen terlarut yang diperlukan oleh mikroorganisme (biasanya bakteri) untuk mengurai atau mendekomposisi bahan organik dalam kondisi aerobik (Umaly dan Cuvin, 1988). Ditegaskan lagi oleh Boyd (1990), bahwa bahan organik yang terdekomposisi dalam BOD adalah bahan organik yang siap terdekomposisi (readily decomposable organic matter). Mays (1996) mengartikan BOD sebagai suatu ...
