The minimisation of material losses involves the optimum combination of the management of internal material cycles (avoidance measures) and environmentally friendly disposal with the maximum possible recycling of any unavoidable surplus materials (external material cycle).
The object of this project was the preparation and progressive implementation of process modifications, including the testing and optimisation of the surface finishing technologies implemented in a user-controllable automatic electroplating installation with approximately 20 separate process stages.
An analysis of actual values has revealed that the rinsing, nickel and chromium subsystems show the greatest potential for savings. The optimisation of systems has therefore focussed upon these subsystems, which are relevant to the modification process.
- Through the optimisation of rinsing technology associated with the ion exchanger cycle, it has been possible to control material flows in the nickel and chromium subsystems in order to achieve the increased recirculation of materials and a significant reduction in the specific consumption of chemicals for the treatment of process water and wastewater. This has resulted in a reduction in specific waste production, with a simultaneous increase in the proportion of wastes recycled.
- The modified subsystems, and consequently the overall system, have proved their effectiveness in the course of long-term testing, based upon considerations of environmental impact, cost reduction, process reliability and quality assurance. The positive impact of modifications to the complete automatic electroplating installation have been demonstrated using a non-specific balance of material flows.
