- 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.

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.)
