Biochemical Oxygen Demand Audit Checklist * (BOD and CBOD)
WebThe microbial sensor BOD values linearly correlated with the BOD-5 values in the 0–60 mg l −1 range of a glucose–glutamic acid (GGA) standard solution, with a 20-min response time. The sensor was marketed in 1983 (Nissin Electric Co.) and successfully used, for instance, to measure wastewaters from fermentation plants. WebBOD—5 The standard oxidation (or incubation) test period for BOD is 5 days at 20 degrees Celsius (°C) (BOD 5). The BOD 5 value has been used and reported for many applications, most commonly to indicate the effects of sewage and other organic wastes on dissolved oxygen in surface waters (see TECHNICAL NOTE). The 5-day value, however, WebWhat is the perfect seed for the BOD test? That’s easy…one that results in the glucose/glutamic acid (GGA) standard having an average BOD of 198 mg/L, and a standard deviation of zero. Obviously, the perfect seed doesn’t exist. So what makes a good BOD seed. Also an easy answer…one that gives an average close enough to 198 mg/L, with a … free people search damit
