20-Inch Big Blue (BB) KDF Filter Cartridge (10D Structure) \u2013 High-Capacity Heavy Metal Removal & Chlorine Neutralizer (10D Structure)<\/b><\/p>\n

The Gold Standard in Heavy Metal Water Treatment<\/b><\/h3>\n

The 20-Inch BB KDF Filter<\/b> is the ultimate solution for complex water quality issues often found in industrial areas or regions with heavy groundwater contamination. Unlike standard carbon filters, the KDF media uses a specialized redox process (oxidation-reduction) to chemically change harmful contaminants into harmless components.<\/span><\/p>\n

Key Features & Benefits:<\/b><\/h3>\n
    \n
  • \n

    Heavy Metal Extraction:<\/span><\/b> Specifically engineered to reduce concentrations of <\/span>Lead, Mercury, Nickel, Chromium<\/span><\/b>, and other dissolved metals.3<\/sup><\/span> It also effectively reduces <\/span>Hydrogen Sulfide (rotten egg smell)<\/span><\/b> and iron.<\/span><\/p>\n<\/li>\n

  • \n

    Extended Filter Life:<\/b> KDF media acts as a “guard” for the activated carbon inside the cartridge. By removing chlorine and metals before they reach the carbon, it can extend the life of the carbon media by up to 10 times.<\/p>\n<\/li>\n

  • \n

    Algae and Fungi Control:<\/b> The KDF process creates an environment that is lethal to microorganisms, preventing “bio-fouling” (slime buildup) inside your filter housing\u2014a common problem in Sri Lanka\u2019s warm climate.<\/p>\n<\/li>\n

  • \n

    Scale Reduction:<\/span><\/b> It helps modify the structure of scale-forming minerals (Calcium and Magnesium), making it easier to clean bathroom fittings and protecting water heaters from hard-water damage.<\/span><\/p>\n<\/li>\n

  • \n

    High-Flow Performance:<\/b> The 20-inch Big Blue design ensures that your water pressure remains strong even when filtering water for a large house, restaurant, or small factory.<\/p>\n<\/li>\n<\/ul>\n

    Typical Applications in Sri Lanka:<\/b><\/h3>\n
      \n
    • \n

      Whole-House Treatment:<\/b> The ideal stage 2 or 3 filter for jumbo systems protecting large villas.<\/p>\n<\/li>\n

    • \n

      Commercial RO Pre-treatment:<\/b> Protects sensitive RO membranes from heavy metal fouling and chlorine damage in 500LPH+ plants.<\/p>\n<\/li>\n

    • \n

      Borehole\/Well Water:<\/b> Vital for neutralizing the metallic taste and odor common in local groundwater.<\/p>\n<\/li>\n<\/ul>\n
