TCMP was added to inhibit nitrification. 25 mL of seed from a laboratory scale reactor was added to each test reactor. Oxygen uptake was monitored using a CHALLENGE AER-200 respirometer for five days. A second dose of 40 and 60 mL of leachate sample was then added to each reactor and oxygen uptake was measured for another 5 ...

Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot of the pattern of oxygen ...

Waste Type: Complex alcohols. Objective: Certain constituents of the test waste were know to be biodegradable but were suspected of being toxic to aerobic biological processes when present in high concentrations. The objective was then to determine how much waste could be added to an activated sludge process before toxic impacts would be ...

Data is used for the calculation of the respiratory quotient, carbon production rate and oxygen uptake rate. The Off-Gas measurement provides the respiratory quotient in a time and space averaged form and with good response time. By comparison data from multiple dissolved species probes are more specific and can provide information about stirring efficiency, aeration and feed distribution within the fermentor. Dissolved gas measurements have ...
