Evaporating installations for waste water in plant manufacturing torula yeast.Peer-reviewed article

V. SÁZAVSKÝ

The article deals with some problems connected with the evaporation and condensation of waste water emerging from manufacturing processes in the Uničov plant producing yeast of Torula class. Experience so far obtained with evaporating units indicates, that the installation suffers from extensive corrosion and incrustations. A suitable thermochemical treatment is therefore necessary prior to evaporation. It may include alkalization by introducing lime, overheating and filtration. After a suitable preliminary treatment regular evaporation can be expected and the installations can be manufactured of current materials. Relation between the boiling point and concentration rate, as well as relation between the concentration rate and the heat transfer coefficient are discussed, too. There various designs of evaporators and their modifications are described in detail.
