  • Influence of cyanide on the anaerobic degradation of glucose

    Bacteria in the anaerobic degradation process convert the substrate to the final products methane and carbon dioxide. Toxic substances can change the process substantially. The purpose of this study was to investigate the influence of toxic cyanide on biogas production in anaerobic degradation of glucose at 40°C. The OxiTop respirometric system offers a quick and simple method for measurement of ...

  • Towards a standardization of biomethane potential tests

    Production of biogas from different organic materials is a most interesting source of renewable energy. The biomethane potential (BMP) of these materials has to be determined to get insight in design parameters for anaerobic digesters. Although several norms and guidelines for BMP tests exist, inter-laboratory tests regularly show high variability of BMPs for the same substrate. A workshop was ...

  • Dreyer & Bosse deliver renewable energy CHP project to Sofia in Bulgaria

    The Sofia council decided to invest in renewable energy to make use of the many tons of biowaste (vegetative material),  20,000 tons per annum, from the waste removal collections that take place daily in Sofia and surrounding area. To make this possible it was decided to go for wet fermentation where the substrate or raw material ferments and the biogas is collected. After three weeks the ...

  • Hydrodynamics characterization of a fluidized bed reactor with an internal circulation of solids (fb-ics). Application to anaerobic methanogenic phase.

    Many advantages of the fluidized beds for the anaerobic treatment are widely reported in literature. Heijnen et al. (1989) comments the following main potential advantages: higher purification capacity, no clogging of the reactor, no problems of sludge retention and small volume and area requirements. Malina and Pohland (1992) denote a high biomass concentrations and long SRT achievable, an ...
