KDF Pre-Filter

KDF 55 & 85 Process Media Aid in Bacteria, Chlorine, Algae Removal in Primary Water and Wastewater Treatment

  • KDF 55 Medium – Designed specifically for removing or reducing chlorine and water-soluble heavy metals. It controls scale, bacteria and algae, even in hot water. The process medium recently received NSF International Certification and is certified by NSF to NSF/ANSI Standard 42 – Drinking Water Treatment Units – Aesthetic Effects. This medium is also in compliance with California’s Health and Safety Code Section 166875 (or commonly know as AB1953) and Vermont Act 193.
  • KDF 85 Medium – Removes or reduces iron and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae.
  • KDF-F (Fines) – Designed to remove chlorine and control bacteria when incorporated into carbon blocks as well as into other matrix-type filters.
  • KDF-C (Coarse Mesh) – Granules are used for removal or reduction of soluble heavy metals and chlorine. For use when less pressure drop is required.

KDF 55 and KDF 85 Process Media can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals. All KDF Process Media forms are effective in controlling the buildup of bacteria, algae, fungi and scale, making them ideal for use in GAC beds, ion exchange resins, carbon block filters and inline carbon filters. Wherever our Media are used, they can eliminate the need for costly, and sometimes harmful, chemical treatments.

Do KDF Process Media offer any other advantages?

In a word, “Yes.” All KDF Process Media are guaranteed for product purity. A certified analytical sheet accompanies each manufacturing run. Patented KDF Process Media are 100% recyclable and contain no chemical additives. Our Medium is classified as a “pesticidal device” by the US Environmental Protection Agency so no pesticidal registration is required. Our Media also meet EPA and Food and Drug Administration standards for maximum limits of zinc and copper in potable water.
