Figure 1: ZERMEG Grid for the anodizing plant of Anodisieranstalt Heuberger
The example of Figure 1 shows the application of the ZERMEG-Grid for the six basic
parameters in the case of Anodisieranstalt Heuberger (see ZERMEG, 2004) to compare the
initial situation (red line) to the results of the optimisation (blue line). The ideal values are
represented by the green line.
ZERMEG focussed on understanding the processes involved in pickling and degreasing of
different metals. For this, a detailed literature research was undertaken to describe the
influences on quality of pickling and degreasing and to prepare models for the use in the
calculations.
The programme routine ZEPRA to calculate ideal consumptions in advance was improved:
Each bath and each separation operation are treated as a blackbox, a closed unit, as
described in the final report of ZERMEG 5 . This allows to add other baths and operations
comparatively easily. For each of these elements a template is programmed, in which the
calculation of the output streams is done from the input streams and all necessary
parameter. Each of these templates characterises a new type which has to be defined in the
program.
In projects like ZERMEG where a lot of very specific knowledge has to be translated to
models this allows for a quick integration to the programme without interfering with other
modules.
