Ancillary equipment

For surface finishing applications

MacDermid Enthone supply surface finishing ancillary equipment for:

Metal recovery
Solution purification

Metal recovery

Technology	Benefits	Features
Chromium recovery	Captures up to 99% of chromium	Leading edge atmospheric evaporation design Use with chromium etching and plating rinses Programmable logic control with remote monitoring capability Discharges air through a scrubber or condenses air in closed loop system
Copper recovery	Captures up to 95% of copper metal	Automated process Re-use copper as solid metal Significantly reduces copper sludge Reduces copper in the rinse water discharge to 2 ppm
Nickel recovery	Captures up to 95% of nickel metal	Automated process Re-use nickel as solid metal Significantly reduces nickel sludge Virtually eliminates nickel in the rinse water discharge
Palladium recovery	Recover expensive palladium metal	Automated process Resell spent palladium metal Does not use expensive resin material in operation Virtually eliminates palladium in the rinse water discharge

Solution purification

Technology	Benefits	Features
Automated pH correction	Reduces costs by eliminating the addition of carbonate salts	Reduces pitting / stardust Curtails chlorine gas emmissions Lowers need for frequent filter changes Improves finish consistency when use auxillary anodes
Carbomax carbonate removal	Removes carbonates from alkaline zinc-nickel plating solutions	Reduces contamination Maintain plating efficiencies No loss of plating solution through purification Produces a dry sludge that can be readily disposed*
Nickel solution purification	Control of organics by removing brightener breakdown by products	Reduces plating defects Removes metallic contamination Lessens frequency for carbon treatements Lowers harmful organics in plating solution
PEARLBRITE satin nickel	Extends the life of satin nickel plating solution	Ability to filter without dosing Precise flow control and regulation Dosing with linear correlation to flow rates Control up to 5 separate Pearlbrite agents with one unit
Trivalent chromium purification	Removes contaminants from plating bath	Performs conductivity check after regeneration Operates automatically with a variable feed cycle Reduces plating defects caused by metallic contamination Programmable Logic Control with remote monitoring capability
ZINCROLYTE KCl-Ni membrane system	Reduce metal consumption and cost of solution disposal	Eliminate anode activation Consistent metal concentrations Reduce consumption of zinc metal Virtual elimination of solution dilution requirements

*For waste treatment, the user is required to know the appropriate local/state/federal regulations for on-site or off-site treatment which may require permits.
