Derouging

Derouging - A process specific to the pharmaceutical industry

The localised electrochemical effects generated by the production of ultrapure water leads to the formation of labile ferric oxides, which then circulate within installations.

Derouging pharmaceutical Networks

Rouging is a phenomenon that requires the implementation of specific curative treatments geared towards eliminating oxides that are redeposited on the top layer of polished or electropolished surfaces :

  • Boilers use in the production of pure steam
  • Distribution of hot purified water/water for injectable preparations, pipe networks, vats
  • Process units, fermenters, freeze-driers

Our high-performance ranges allow full derouging at low temperatures without damaging the substrates. Perfect restoration of process surfaces guarantees the durability of any treatments applied.
