Oxygen monitoring from aerobic and anaerobic for biodegradation tests
Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test ...

Analytical Instruments for Biodegradability & Compostability
Instrument for biodegradability analyses. The degradation of biodegradable polymers and biodegradable plastics crucially depends on the environments they may end up in, such as soil, fresh or marine water, landfill or composting site. Owing to the great variations in natural conditions, several tests are needed to determine the fate of a polymer material in real life and to study its biodegradability in different environments. In aerobic environments, the biodegradability is usually determined by measuring ...

Respirometry solutions for industrial waste treatability industry
Test Setup: 40 and 60 mL of wastewater were added to individual respirometer flasks each containing nutrient/mineral/buffer medium to form two different dilutions. 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 ...

Application of respirometry system for biodegradation testing
The pattern of oxygen uptake– relative to that for a control substrate – gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample. In this case, samples #2 and #3 showed a much lower biodegradation rate than the ...

Respirometry solutions for pharmaceutical wastewater industry
A pharmaceutical company was interested in knowing whether a specific component, MCB, inhibited the biodegradation of other wastewater constituents. A series of respirometer tests was set up using identical mixtures of wastewater and return activated sludge (RAS) plus varying amounts of MCB. The OUR fingerprint of this wastewater includes a first peak of about 500 mg/L-hr within the first hour of contact that represents the oxidation of highly-biodegradable organic constituents. A second group of readily ...

Respirometry system for anaerobic biochemical methane production
Anaerobic biodegradation tests – often referred to as Biochemical Methane Production (BMP) tests – involve addition of known amounts of a chemical or wastewater to anaerobic cultures. The quantity of methane production – relative to that from a control – indicates the biodegradation potential. This case study shows methane production for a Control reactor and three test reactors that were operated at 20-, 30- and 45-day retention times and received three doses of industrial wastewater. The ...

Analytical Instruments for Wastewater Treatment
Respirometer based on gasometric method for wastewater analysis. In any biological wastewater treatment system, there is a need to define, assess and understand the plant’s performance with regard to the removal of certain contaminants and the response of bacterial activity to inhibitory compounds of interest. The execution of batch activity tests can be useful to study the biodegradability of a given wastewater stream, determine the stoichiometric and kinetic parameters involved in the conversion of a ...

Respirometry system for determination of biodegradation kenetics
Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentrations of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen ...
