All the responses have included just chemical regen options, but ORP can be
maintained with electricity. FSL manufactures an Electroletically
Regenaration Unit that maintains ORP without adding in needless water (H2O2).
 The capitol investment is high but the ROI is quick, if all cost considered.
With chemical regen system costs would include the chemistries, HCL and
Chlorine/H2O2/or Sodium Chlorite. The amount of HCL used in any system will
depend on the type of Oxidizer.  The waste cost is a factor, in house
treatment or off sight treatments. With the FSL unit the regen cells plate
out almost pure copper that can be sold, with no waste treatment discharge.
HCl is used to maintain Normality but at a much lower consumption rate than
the chemical oxidizers.  I have seen two diffirent insallation in the New
England area that has been up and running.
I do not represent FSL. I'm just giving other alternatives for Cupric
Chloride Regen.
I am unsure of any down side to this system. If anyone has any input please
feel free to comment.
