SYSTEM FOR PRODUCTION OF BIOGAS USING LIQUID MIXTURE OF WATER PURIFIED FROM LIQUID AFTER SPLITTING AND DRY ORGANIC SUBSTANCE Russian patent published in 2025 - IPC C02F11/04 B09B3/00 

FIELD: biogas production.

SUBSTANCE: group of inventions relates to production of biogas using a liquid mixture of water purified from liquid after splitting and a dry organic substance. System comprises a tank for liquid mixture 27 for mixing and containing water purified from liquid after splitting and organic dry substance, tank for fermentation 11 of the mixture taken from said tank for liquid mixture 27. System comprises settling tank 37 for separation of liquid after fermentation into solid and liquid phases, and subsequent direction of water into tank for liquid mixture 27, and pulp – into storage tank 13. System comprises gas holder 12 for storage of methane gas taken from said fermentation tank 11, and tank for storage 13 of split sludge and pulp. Deodorising furnace 14 is configured to use methane gas taken from gas holder 12 as fuel. Electric power generation boiler 15 is configured to use methane gas from gas holder 12 as fuel. Dryer 16 is configured to dry food wastes, as well as said split sludge and pulp taken from storage tank 13.

EFFECT: increase of production, increase of dry substance production and rate of resources processing.
