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.
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.
