A method of treatment of an aqueous effluent stream obtained during production of furfural is disclosed. The aqueous effluent stream containing organic solvents, furfural, and water is subjected to azeotropic distillation to obtain a distillate stream and a treated effluent stream having lower BOD and COD values which can be further reduced by biomethanation.

Method of treatment of aqueous effluent

Processes for the preparation of furfural from a xylose containing feedstock and more particularly to an elevated temperature conversion of a xylose containing feedstock to furfural in acidic conditions are described. The described process uses a mixture of two solvents in which the humins are formed and solubilized. The described process is operated in continuous mode with no significant amounts of solid by-products formation.
