Remove grit as well as plastics
prior to biogaz reactor
The grit, heavy inert fraction, exits Depackagers with the organics outlet.
Grit represents an important maintenance cost for Biogas Reactors, and is undesirable in the final digestate.
The Seditank removes the grit and plastics prior to entering the Biogas Reactors.
Removing all plastics including micro plastics and reprocessing them in a TWISTER separator
In response to the rising concern about “visible plastics” in the solids or liquids that are beneficially used, Drycake developed up method to prevent plastics from entering the anaerobic digester: the Seditank-Plastifloat.
As a single step in very small plants or as a second step, a Sediwash can be used to further recover organic matter. By washing the grit, the final weight of the grit can be reduced by 60% and the gas yield can be increased by 1%.
Furthermore, as the separated grit is drier it can assist in the liquid balance of the plant
The Sediwash can be used as a single step in Sand Bedding Washing and Recovery.
