Savings thanks to internal wastewater treatment
High waste management costs for the disposal of industrial wastewater prompted Anka-Draht to think about ways to save money and to procure a wastewater treatment plant. The purification of the electroplating wastewater and the used wire drawing emulsion is now carried out by two “Vacudest” evaporators.
Wire as thin as 50µm, which is thinner than a hair, can be produced by means of wire drawing. On the left, three wires made by Anka-Draht (on the right, a hair). © H2O
The “Vacudest M” treats the used emulsion from the drawing process so efficiently that the treated water is suitable as the basis for the new wire drawing emulsion. © Anka-Draht
The “Vacudest S” reliably separates heavy metals and complexing agents from the electroplating rinse water used by Anka. © H2O
The “Vacudest M Clear Cat”converts the wire drawing emulsion into crystal-clear distillate. © H2O
