ORIGINS
Akdolit® started its history about 50 years ago as a small company producing water treatment reagents for application mainly in filters. Thereafter, Akdolit® grew into a force brand in the water treatment reagent industry. After several business changes, it became first part of the Lhoist Group and is today also part of Lhoist Western Europe.
