Removal of Chlorine in a Municipal Water Treatment Facility
 

KDF® 55 Process Medium Helps with Chlorine Removal in a Municipal Water Treatment Facility

A Los Angeles-based maker of fashion jeans uses KDF® media instead of chemicals for removing chlorine when treating municipal water in their stone-washing process.

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. (More information on how KDF® 55 process medium work.)

  • National clinical laboratory used KDF® 55 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 KDF® 55 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 company.
  • Major U.S. blue jean manufacturer uses KDF® 55 Medium for pretreatment to ion exchange systems at 600 gpm; 175 gpm also used for reclaiming plant's waste stream from production.
  • KDF® Process Medium are being used to complement or replace activated carbon filters, removing up to 95% of the chlorine when treating municipal water. KDF® Media pretreatment of granular activated carbon also extends the carbon's life and limits bacteria growth in the bed.
