Reduce hexavalent chromium

RedOx3 is Swedish Hydro Solutions' reducing treatment used to reduce hexavalent chromium. The product was developed in our laboratory for a project managed by the Swedish Transport Administration.

Hexavalent chromium is a common contaminant in construction and infrastructure projects, such as during the production or handling of cement. It can also occur during grouting, when washing cement trucks, and during the demolition of old concrete. Hexavalent chromium is environmentally hazardous and can also harm human health.

Effective

Effectively removes hexavalent chromium from water, often achieving a reduction of 95-99%.

Safety Classified

Highest rating in Basta and recommended content according to the construction product assessment.

Cost-Effective

RedOx3 is cost-effective compared to other methods on the market.

How it works

The treatment with RedOx3 works by reducing highly water-soluble hexavalent chromium to less water-soluble trivalent chromium. This allows the trivalent chromium to precipitate and then be flocculated in Swedish Hydro Solutions' HydroBox using the flocculant chitosan, ultimately allowing the flocs to settle in a sedimentation tank.

Projects

The new Näckenbadet

Open dialogue, creative solutions, and Nacka Municipality's good communication about the site's history and condition created good conditions for an efficient, full-scale water treatment system.

The Varberg Tunnel

Stricter regulations impose new requirements on chromium treatment. In the Varberg Tunnel, the issue was effectively addressed using RedOx3 and chitosan flocculation from Swedish Hydro Solutions.

Johannelund

In the extensive tunnel construction project along the new E4 highway (Stockholm Bypass - Johannelund), there was a need to reduce the amount of hexavalent chromium.
