ABSTRACT:
A plating system includes a plating tank and a separation tank connected in a closed loop. Toxic bubbles or fumes are generated during plating which rise above the plating solution in the plating tank. Venturi and/or vortex scrubbers scrub the bubbles as the solution is drained from the plating tank to the separation tank. The toxic fumes are sucked into the primary scrubbing tube while the solution is drained from plating tank into the separation tank. The fine fumes are then forced through the secondary scrubber/filter. The solution once in the separation tank is then pumped back into the plating tank.
