    The device is an ion exchanger. It is therefore used to extract ions from media, in this case water. This can be ensured, as long as the device has “space” for the ions. This unit is reprocessed with acids and alkalis after it arrives at the factory. This process lasts from several days to several months, so all materials worked with should be fully resistant to the corrosive and abrasive effects of said media. The device already exists and is now to be extended with useful features for the plant and customers. These various sub-items are assigned as one package, various packages, or separately, depending on competency. The developments of the sensor technology, as well as the processing of the electrical signals resulting from this, are the priority tasks. For further in...
