Current Limits in Aeration Technology

Put a steel pin or a small aluminium disk gently on the surface of water and it will make a slight dent but it will stay there. It will not sink, even though both aluminium and steel have a lot higher density than water. This demonstrates the toughness of any normal water surface, where water […]

Biological Desulphurization of Biogas

Biogas basically consists of methane and carbon dioxide. In addition, it also contains unwanted contaminants, especially hydrogen sulfide (H2S). Hydrogen sulfide mainly occurs because of the degradation of sulfur-containing proteins (e.g. methionine and cysteine) or the desulfurization of sulfates. The fermentation of manure and other organic wastes shows typical H2S concentrations in the range of […]
