Recover Dragout
Chrome PlatingRemove 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. |
