Separation by continuous centrifugation

Efficiently and economically recover all components contained in the coating effluents

The technology of separation using centrifugation is a patent pending ABB solution which enables to recover efficiently and economically all components contained in the coating effluents in order to reuse them in the composition of fresh coating colour.

A two-stage treatment

Effluents are treated at low solid content through a two-stage treatment : 
  • 1st stage = chemical treatment by mixing effluents with additive to improve the separation of mineral and organic components, 
  • 2nd stage = physical treatment using a centrifugation unit to separate the mineral and organic components from the filtrate.
