Abstract
A process for the enzymatic streatment of waste water of wheat starch plants in which the waste water is subjected before or alternating with the first steps of the concentration process to a process at least consisting of (a) a heat treatment followed by separation of the solid substance, and (b) a treatment with enzyme preparations exhibiting amylase and/or cellulase and/or hemi-cellulase activity and optionally glucoamylase and/or .beta.-glucanase activity.
Claims13
A process for the purification of waste water of a plant for the production of wheat starch wherein said waste water is subjected, in any sequence, to treatment steps comprising:
- (a) a heat treatment followed by the separation of the solid substance;
- and
- (b) a treatment of said waste water with one or more of the enzymes .alpha.-amylase, cellulase, and hemicellulase and, optionally, with one or more of the enzymes glucoamylase, and .alpha.-glucanase.
A process for the purification by concentration and simultaneous enzymatic treatment of waste water of a plant for the production of wheat starch wherein said waste water is subjected before, or alternated with, the first steps of said concentration, one or more times, to treatment steps comprising:
- (a) a heat treatment followed by a separation of undissolved solid substance;
- and
- (b) a treatment of said waste water with enzyme preparations having .alpha.-amylase, cellulase and/or hemicellulase activity.
