Bau, Erprobung und Optimierung einer abfallarmen und abwasserfreien Galvanik Abschlussbericht

Considerable amounts of solid waste to be dumped and large volumes of waste water to be drained are resulting from running conventional electroplating plants. Therefore, the main efforts outlined in this final report have been to decrease the amounts of solid waste and to avoid waste water completely (zero-discharge). The following technologies have been applied: separate collection of rinse water streams, multiple step rinsing systems to reduce water consumption, direct recirculation of rinse water, recirculation by vacuum evaporation and vapour recompression evaporation and regeneration of process solutions. All procedures have been applied in a large scale production (three shift operation). This project demonstrates that an advanced low-waste technology in practical electroplating is profitable.
