Modern engineering as exemplified by the development & modelling of the rotating cathode cell [Modernes engineering am beispiel der entwicklung und modellierung der wälzkathodenzelle]

Abstract

The rotating cathode cell is an electrochemical reactor for treatment of process effluent by removal of metal ions in solution. Initial experiments were carried out using a small laboratory unit. In order to develop full-scale industrial size units rated at up to 500 Amp, while holding development costs to a minimum, the system was mathematically modelled in order to characterise the main parameters. Various models were used, with a range of complexities. By calculations using actual data and optimising the models used, a full-scale barrel with cascaded rotating cells, and a multi-stage reactor were brought to the production stage with a minimum ox expensive full-scale practical experiments.
