Austrian Plant Removes Arsenic From Water

Why this is here: The AROX plant can currently purify up to 20 liters of water each second, with plans to expand to 30 liters per second in a second phase.

Wolfsberger Stadtwerke in Austria recently completed the AROX drinking water treatment plant. The new facility addresses arsenic found in local spring water, originating from crystalline rock layers. The plant uses iron oxide to bind with the arsenic, causing it to rust and then be removed from the water supply.

AROX currently treats roughly 20 liters of water per second. A second expansion phase aims to increase capacity to 30 liters per second. The project represents an investment of about three million euros for the regional water supply.

Alongside AROX, Wolfsberger Stadtwerke is finishing the Koralmleitung pipeline to secure future water sources. They also plan to build two hydropower plants, generating electricity from flowing water. The long-term effects of this method and potential scaling issues remain to be studied.
