Industria Galvanica Dalla Torre, Italy – Chromium Treatment System
In 2013, ToxSorb began working on its most ambitious project to date, a high volume chromium remove and reuse project at an Italian Galvanic factory named Dalla Torre, specializing in decorative chrome and nickel-plating of furniture.
In the past, Dalla Torre relied on traditional means of chemical / physical treatment, reducing hexavalent chromium using sodium metabilsulfite, before precipitating the trivalent chromium with caustic soda and discharging the treated wastewater to the sewar system. While this system complied with local Italian regulations, it was inneficient in its use of water, electricity and chemicals and produced high quantities of sludge. Dalla Torre was looking for a solution that would maximize the reuse of water back to the process, while generating significant cost savings in the process. ToxSorb’s unique technology for chromium removal and reuse answered all of the client’s requirements.
