Hermetic refrigerant compressor

The invention relates to an electrochemical electrolyte cleaning method using plastic-diamond composite electrodes. The electrolyte is generally liquid waste from chemical or electrochemical methods.The bipolar plastic-diamond composite electrodes (2) are assembled as purpose-made curved structures to form stacks of cells, thus constituting the core of the electrochemical reactor. In an alternative form of embodiment, the bipolar electrodes are used, in the form of balls (12), in a fluidised-bed reactor or a fixed-bed reactor.
