 PLATING * MACHINING * PRINTING Recover Dragout
Chrome Plating

Remove Water from ANY Waste Water Solution.  If a bath can be air agitated without causing excessive foam, it should be well suited to this method of recovery. High cyanide baths and still nickels are examples of solutions that should be tested for foaming. A sample can be shaken in a glass jar to see if the foam disappears quickly.

Evaporation eliminates water and leaves all the plating chemicals (and tap water impurities) in the process tank. If your bath is not continuously filtered (as are some bright nickels), you may want to consider using D.I. or R.O. water in the rinsing chain. 

HOW MUCH RINSE WATER DO YOU NEED?

Counterflow rinsing reduces rinse-flow requirements making dragout recovery practical and inexpensive. The table indicates the water needed to produce a 5,000:1 ratio using most plating solutions, or 20,000;1 using chromic acid.

Dragout Concentrations GPH of RINSE WATER NEEDED FOR EACH GALLON OR DRAGOUT*
one rinse COUNTERFLOWING RINSES
2 3 4 5
Most Plating Solutions 5,000 71 17 8 5
CHROME,40 oz./gal. 20,000 141 27 12 7
*For 2 GPH dragout, multiply by two, for 1/2 GPH multiply by .5, etc. (flow rates are rounded to the nearest gallon)
