  • Anaerobic Biomass Activity Tests

    Anaerobic Biomass Activity Tests The methane production activity of anaerobic sludges is related to the history of the sludge, the biomass yield from the wastewater the sludge has been treating, the fraction of methanogens, and the presence of toxic substances. Best performance can be achieved from an anaerobic treatment plant if the operator measures the Specific Methanogenic Production (SMP) ...

  • Use of anaerobic respirometers for measuring gas production in toxicity and treatability tests

    Introduction Anaerobic processes are used widely for stabilizing domestic sludges, treating industrial wastes, and converting biomass to methane. These processes frequently receive complex organic chemicals that are classified as being hazardous or toxic. Despite advances in our understanding of anaerobic reactions, there is limited information regarding the impact of toxic chemicals on ...

  • Anaerobic BMP and ATA Tests

    Anaerobic BMP and ATA Tests Biochemical Methane Potential (BMP) tests involve addition of test chemicals or wastewater samples of concern to an anaerobic culture that is contained within a sealed vessel. Methane or total gas production are measured over periods ranging from 1 to 60 days without addition of new chemical or wastewater sample. Modern BMP tests usually involve multiple additions of ...

  • The Challenge AER-200 Respirometer System for anaerobic applications

    The CHALLENGE AER-200 Respirometer System consists of one or more biological reaction vessels, gas flow measuring cells, and a computer. The gas measuring base contains eight flow cells and associated interconnecting circuitry. As gas flows through each cell under the influence of a slight pressure caused by gas production in the reaction vessel, bubbles of a fixed volume are formed in the lower ...

  • Treatment of oil contaminated soil from a wyoming refinery

    An oily soil sample was shipped from the refinery site to the test Laboratories on June 17, 1995. The sample was stored at 4 °C until testing began. The sample was in the form of a dense pasty mud, black in color, and consisted of oily residues mixed with what appeared to be bentonite clay. Characterization showed the ...
