METHOD OF PREPARATION OF ORGANIC-MINERAL MIXTURES FROM LIQUID WASTES OF ALCOHOL PRODUCTION Russian patent published in 2008 - IPC C12F3/10 

FIELD: technological processes; chemistry.

SUBSTANCE: method includes coagulation and deposition of organic-mineral substances by introduction of defecation mud or slaked lime into liquid wastes of alcohol production in the amount of 10-100 kg of dry weight per one ton of liquid wastes and polyacrylamide in amount of 10-100 gram per 100 liters of liquid wastes and further pumping of deposited mixture. Sapropel or peat may be introduced into liquid wastes in amount of, accordingly, 10-200 kg or 10-1,000 kg of dry weight, per 1 ton of liquid wastes. Microelements and mineral components may be added to deposited mixture of organic-mineral substances. Invention makes it possible to recycle wastes of both alcohol and sugar production with preparation of organic-mineral fertilisers of pointed action and forage.

EFFECT: this technology is ecologically safe.
