Like the five day Biochemical Oxygen Demand (BOD5) it ... Biochemical Oxygen Demand The biochemical oxygen demand (BOD) of water determines the impact of decaying matter on species in a specific ecosystem. Sampling for BOD tests how much oxygen is needed by bacteria to break down the organic matter. Importance of Dissolved OxygenApr 29, 2019 · Bacteria naturally decomposes organic matter, but requires oxygen to do so. The larger and more numerous the organic matter, the more oxygen required to eliminate organic matter. The rate at which wastewater requires oxygen is known as the biological oxygen demand (BOD). BOD is a crucial factor in refining wastewater. Biochemical Oxygen Demand is an important water quality parameter because it provides an index to assess the effect discharged wastewater will have on the receiving environment. The higher the BOD value, the greater the amount of organic matter or “food” available for oxygen consuming bacteria. Biochemical oxygen demand or BOD is the amount of oxygen required to decompose organic matter in one litre of polluted water. If the water is more polluted, more will be the BOD because more will be the organic matter present in it and hence, more oxygen will be required to decompose it. 4. Biochemical Oxygen Demand as a Cause of Water Pollution Biochemical oxygen demand (BOD) is an indirect measure of the concentration of biodegradable organic matter in water or wastewater. Organic matter (as measured by BOD) is one of the major constituents removed from wastewater in domestic wastewater treatment plants. The reason for being BOD is the total amount of dissolved oxygen used or needed for respiration in water at a given time BOD increases with increasing organic matter In 2010, the dead zone in the Gulf of Mexico expanded because of the unprecedented oil spill caused by the Deepwater Horizon oil well explosion. 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).
