Biodegradation Testing Applications

  • Premium

    Oxygen Monitoring from Aerobic and Anaerobic for determination of biodegradation kinetics by respirometry

    Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentration 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 uptake.

    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 sample.

  • RDF

    RDF (Refuse Derived Fuel) is made from domestic waste which includes biodegradable material as well as plastics, and has a lower calorific value than SRF (Solid Recovered Fuel). RDF (Refuse Derived Fuel) is used in combined heat and power facilities, many of them in Europe where they produce electricity and hot water for communal heating systems in the local area. Compared to landfilling, the lower carbon emissions resulting from RDF manufacture outweigh the emissions associated with transporting the reclaimed...

  • Enhanced anaerobic biodegradation for the soil and groundwater industry

    Enhanced anaerobic biodegradation is the practice of adding hydrogen (an electron donor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms performing anaerobic bioremediation (reductive dechlorination) on any anaerobically degradable compound or chlorinated contaminant. The most commonly targeted chlorinated groundwater contaminants are primarily used in industry as degreasing agents and include: Perchloroethylene (PCE), Trichloroethylene (TCE), Dichloroethylene (DCE),...
