CERN - Wastewater technology for treating wastewater from electroplating shop

The European Organisation for Nuclear Research (CERN), based in Geneva close to the Swiss-French border, is the world’ s largest and most important particle physics laboratory. The particle accelerator, an underground circular tunnel measuring 27 km in length, has been built to help solve scientific conundrums concerning the origins of the universe and the structure of matter.

The CERN site has its own electroplating shop, which gives rise to wastewater containing cyanide and chromate. The wastewater undergoes physico-chemical treatment in batches inside two Envochem® DOX plants. Approximately 2 m3/d of wastewater containing cyanide and 30 m3/d of wastewater containing chromate are involved. The wastewater treatment plant is prepared for operation without producing any wastewater. An evaporation plant can be retrofitted for this purpose.

In addition, ultra-pure rinsing water is produced using a softening plant, reverse osmosis and electrodeionisation with a capacity of 4 m3/h.

EnviroChemie was the main contractor for the project, which included the new hall. 

Plant completion date: 2009
