I'm looking for verification of an explanation that was given to me regarding the use of an ORP Controller to feed a sulfide (NaHS, DTC, etc.) to remove metals.
I'm aware that ORP measures the Oxidation/Reduction Potential, so using an ORP Controller to feed bleach or metabisulfite to a...
ACHRISTIDE,
Thanks for your response. The proportional pump set-up makes sense except I worry that the dissolved metal concentration in the untreated waste water changes at various times (e.g. 9AM - Cu=10 ppm, 11AM - Cu=0.5 ppm, 3PM - Cu=35 ppm). The OPR meter is hyped as a cure to metal...

The application is for a mine in the Western US. The groundwater is removed from the mine pit to keep it dry - then the groundwater is discharged in another location after it meets local limits...
