Wallenius Water Innovation AB

Our journey began in the early 2000s when our sister company, Wallenius Lines, began to seek a solution to one of the main environmental challenges in their operations – the spread of invasive species through the ship’s ballast water. 

The development of the Wallenius AOT (advanced oxidation technology) and the ballast water treatment system PureBallast* have given us a cutting edge competence within water purification. 

Since then, we have developed products to solve several sustainability challenges upstream. We halt the decline of the groundwater levels in China by helping fish farmers to recycle their water, and in Swedish and German workshops, we improve the work environment for an increasing number of operators. 

*Is developed together with, sold and marketed by Alfa Laval.
