  • the percolators are operated in parallel, ie the hydrolyzate of each percolator is passed, possibly via an intermediate buffer, into the methane reactor.
  • the output of the percolators By superimposing the output of the percolators, whose contents each have different residence times, one expects a homogenization of the hydrolyzate quality and quantity and thus also of the resulting methane gas. (Fig. 1). It is known that the biochemical conversion in the hydrolysis immediately after the entry of fresh input material is very high, since first the rapidly degradable substances are degraded. At this stage, therefore, a very rapid increase in the hydrolysis bacteria takes place, which is also associated with the increased production of enzymes.
  • DE 199 37 876 C2 discloses a process for the biological conversion of organic substances to methane gas, in which organic wastewaters, but no solids, are hydrolyzed. The hydrolyzate is recycled, with an increase in the concentration of hydrolysis bacteria by membrane filtration and recycling of the filter residue.

  • DE 198 46 336 A1 comprises many variants for a waste treatment, which include, inter alia, a two-stage hydrolysis.
  • this two-stage nature is due to the tasks of mechanical material flow separation to be solved because the hydrolysis apparatus flows continuously through the material stream of the biogenic material, in this case "waste in particular.”

  • This material flow guidance ensures that the high concentration of hydrolysis bacteria and enzymes in fresh input material is still available for the hydrolysis process of older input material, so that a much more efficient degradation of the less degradable organic substance is possible.
  • the high acid potential (low pH value) from the hydrolyzate of the fresh input subset also ensures a low pH value in the case of percolation of the subsequent subsets.
