KDF PROCESS MEDIA FILTRATION

High-purity copper-zinc redox media consistently remove 99% of free chlorine by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions.
  • 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.

What Are KDF Media?
  • KDF process medium are being used to complement or replace activated carbon filters, removing up to 95% of the chlorine in municipal water. KDF media pretreatment of granular activated carbon also extends the carbon's life and limits bacteria growth in the bed.
