21. Biochemical oxygen demand of the water in 2004 was 0.1 mg / L, which means good condition. 22. The International Organization for Standardization describes a standard method for measuring chemical oxygen demand in ISO 6060. 23. However, oxygen demand is leached into the wastewater flow through the filter as worms digest retained solids. 24. The actual oxygen demand can be measured experimentally and is called the biochemical oxygen demand ( BOD ). 25. Rich mixture causes an oxygen demand . 26. The actual oxygen demand can be measured experimentally and is called the biochemical oxygen demand ( BOD ). 27. Those biochemical reactions create what is measured in the laboratory as the biochemical oxygen demand ( BOD ). 28. In severe gastrointestinal bleeding, there can also be a mismatch between oxygen demand and supply of the myocardium. 29. Angina occurs when the arteries are unable to satisfy the oxygen demands of the heart muscle, he explained. 30. Simultaneous Chemical oxygen demand , and Nitrogen and Phosphorus removal, can be easily integrated in a discontinuous fed system.
