ZERO PLUS - Best Technologies applied to bright nickel rinses (Barrel Line)

The treatments of galvanic baths with simple salts and their rinses, as in the case of bright nickel, in a closed loop by means of techniques such as vacuum evaporation are considered as BATs in the BREF document “Surface Treatment of Metals and Plastics”. The ZERO PLUS Project performed new ecoapproximations for vacuum evaporation as a drag-out reduction technique, rather than a concentration technique, applied to a nickel barrel line. Regardless of the unfavorable result of the final economic feasibility study, and its negative contribution to the candidacy of the application herein described as BAT, this article provides interesting information that the BREF should consider during its new reviewing period.
