Hard chromium plating
Treatment and recycling with vacuum evaporator of rinses from an hard chromium plating line.
The process foresee a filtration of the rinse water before the evaporation process with ion selective resins in order to remove metals other than Chrome.
Distilled water produced by the evaporator is recycled in closed circuit while the concentrate is also recycled in the Chromating tanks for a Zero Discharge System.
350 lt/h of distilled water produced
8000 lt/day of recycled rinse water
Heat pump vacuum evaporator with refrigerant R407C
Heat exchanger in Titanium and Boiler internally coated in HALAR
Recycling of the 90% of the treated water
