Surface treatment plant reference

Surface treatment and coating plant Piiroinen Oy at Salo Finland

Problem:

High zinc, chrome and nickel content on waste water effluent

Solution:

VodaMetal heavy metal adsorbent to settling process and process optimization

Adsorbent sludge was fed to flocculation process

Results:

Ni, Cr and Zn levels lower after settling than normally after ion exchange

Reduced NaOH and flocculant chemical costs ==> total saving over 28%

Reduced mass change on ion-exchangers
