The plant projected by EBNER is part of a customer’s package of measures to achieve the aim of reducing waste water of several factories. These measures represent Europe’s largest individual investment in the history of this customer and are because of high media interest of greatest importance. With this project the customer once again placed his trust in the competence of EBNER mainly due to the fact of the cooperation between the two companies for several decades. Thus EBNER could handle its first project in large-scale plant construction.
The existing waste water is evaporated in a triple-stage evaporation plant and salt is crystallized for the time being. A multistage pre-heating route was realized in this case to ensure minimum primary energy consumption in form of fresh steam.
The third stage of the plant has such a dimension (diameter evaporator 6,8 m) so that this was executed twice. The other components of the plant also represented a special challenge in this case. So, the heater of the second stage with a weight of approx. 120 tons is the heaviest apparatus being built by EBNER in one piece.
