Stelmi’s chromium baths are closed-loop and release no wastewater which eliminates the need for special discharge permits. The enclosed plating machines work slightly under normal atmospheric pressure; the vapors are continuously collected and treated with both dry and wet scrubbers, recycling the condensation into the baths. The impact on the environment is negligible, both inside and outside the plant, and is well below the regulatory thresholds. Redundant containment systems are utilized to eliminate any risk of leaks or spills of liquid solution.
