3. Concentration of rinsing baths

3.1 Static baths

Their concentration is intended to :

  • reduce storage volumes;

  • reduce the volumes to be transported, if recovery and elimination treatments are carried out outside the company in an approved center;

  • have an appropriate concentration in case of "rising" in the treatment baths;

  • facilitate subsequent in-house recovery processes using smaller-scale equipment.

Concentration is said to be "global" when all constituents are equally concentrated. It is called "selective" in the opposite case.
