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.
