ANAEROBIC MEMBRANE-TYPE BIOREACTOR FOR PROCESSING OF WASTES FLOW Russian patent published in 2015 - IPC C02F3/28 

FIELD: process engineering.

SUBSTANCE: invention relates to processing of wastes flows containing general biodegradable solid substances. Wastes flow with said components is fed to anaerobic reactor wherein said components react with microorganisms for biological destruction of components and production of biomass and biogas. Mixing occur in selected sections of anaerobic reactor, particularly, at reactor top and bottom sections. Relatively heavy solid substances are deposited at bottom and mixed with the solution being mixed while relatively light or fine solid particles surface at anaerobic reactor top section and mixed with said solution being mixed. This occurs in mid part of anaerobic reactor where concentration of solid particles is relatively lower than that at anaerobic reactor top or bottom parts.

EFFECT: maximum possible flow rate through membrane, ruled out or prevented contamination, longer service life.
