Surface treatment plant reference
Surface treatment and coating plant Piiroinen Oy at Salo Finland
Problem:
High zinc, chrome and nickel content on waste water effluentSolution:
VodaMetal heavy metal adsorbent to settling process and process optimization
Adsorbent sludge was fed to flocculation processResults:
Ni, Cr and Zn levels lower after settling than normally after ion exchangeReduced NaOH and flocculant chemical costs ==> total saving over 28%
Reduced mass change on ion-exchangers
