High-purity copper-zinc redox water filter media consistently provides 99% of free
chlorine removal from water by electrochemically reducing dissolved chlorine gas to
water-soluble chloride ions.
- National clinical laboratory used this medium as a pretreatment to reverse
osmosis membranes for high-purity. System has been in operation for 9 years at
6,000 gallons per day.
- Northeastern U.S. commercial laundry facility uses redox process medium as a
pretreatment to ion exchange resins at 200 gpm (gallons per minute). The switch
from granular activated carbon (GAC) represented a major cost savings for the
- Major U.S. blue jean manufacturer uses redox medium for pretreatment to ion
exchange systems at 600 gpm; 175 gpm also used for reclaiming plant's waste
stream from production.
- Redox process medium are being used to complement or replace activated
carbon filters, removing up to 95% of the chlorine when treating municipal water.
This pretreatment of granular activated carbon also extends the carbon's life
and limits bacteria growth in the bed.
