Media filtration is a water treatment process that uses granular material to remove impurities. This form of filtration also aids in removing biological matter such as bacteria, algae, protozoa and other pathogenic micro-organisms. Filtration efficiency, backwashing, media replacement, media regeneration requirements, and filtration performance monitoring are all considered when identifying the applicable filtration option. At Delco Water, we offer a wide variety of different types of media filtration that can be used as a standalone treatment or integrated to a larger treatment system. 

Types of Media Filtration

  • Ceramic Media

    • Filralite
      • A highly porous engineered ceramic media that offers significantly better performance than other filter media

  • Adsorptive Media

    • Adsorptive media is a physical/chemical process where dissolved constituents are attracted chemically to the media
    • Activated alumina
      • Primarily used to remove arsenic and fluoride
    • Granular activated carbon (GAC):
      • Primarily used to remove chlorine and dissolved organics

  • Catalytic Media

    • Catalytic media is used for enhanced efficiency for iron, manganese, and arsenic removal
      • DM165, Katalox, or Pyrolusite

  • Greensand

    • Greensand is specifically used to remove iron, manganese, and arsenic. We use a chemical oxidant like chlorine or potassium permanganate to oxidize incoming dissolved iron or manganese
      • GreensandPlus

  • Sand & Anthracite

    • This type of filtration is most effective in removing suspended particles such as sand and clay, as well as turbidity

  • Ion Exchange

    • Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge
      • Sodium cycle
        • Hardness and organics removal
      • Hydrogen cycle
        • Used for complete demineralization of water
