  • Granular Activated Carbon

    A9031A

    Water Tech supplies a variety of Granular Activated Carbon (GAC, PAC) filter media to remove organic compounds, color, and / or extract free chlorine from water for reverse osmosis (RO), nano filtration (NF), manufacturing processes, discharge, and other applications.

    Granular Activated Carbon remove impurities through adsorption and contact time. Free chlorine removal is the result of residence time in contact with the carbon, rather than filter surface loading, with standard design of typically 2 to 6 gpm / ft3 of carbon bed. Chloramines are significantly harder to remove than chlorine, and require an extended period of contact with the activated carbon, referred to as empty bed contact time (EBCT).

    Our Activated Carbon Media Types Include:

    • Bituminous: Coal based granular media.
    • Coconut Shell: Superior hardness; high activity level; trihalomethane removal; long life.
    • Acid washed: Increased adsorptive capacity, low pH applications.
    • Catalytic: Specialized to remove hydrogen sulfide gas, iron, and chloramines.

     

    Contaminants Removed by Our Granular Activated Carbon Include:

    • Chlorine
    • Color
    • Organic Substances and Chemicals
    • Fertilizers
    • TCE (Trichloroethylene)
    • EDB (Ethylene dibromide)
    • THM (Trihalomethanes)
    • Sediment
    • Chemical Odor
    • Pesticides
    • Detergents
    • Chloramines
    • Others

     

    Water Tech carbon filter tanks and systems are also available in all sizes.

  • Sand, Gravel, Anthracite & Garnet

    Commercial Activated Carbon Filters Watts1016

    Reliable Suspended Solids (TSS) and Turbidity Removal

    Water Tech high quality anthracite, sand, garnet, and gravel filter multi-media, and engineered filter systems provide reliable removal of suspended solids and turbidity in water treatment applications.

    Multimedia water filters utilize anthracite, sand, gravel, and garnet with a gravel under bed, chosen for their distinct density and size differences. Anthracite - the lightest, most course media at the top, sand in the middle, and garnet - the heaviest, finest media at the bottom.

    This filtration layering allows the largest contaminants to be trapped in the top filter layer, with smaller particulates sifting farther down into the lower layers, providing more efficient turbidity removal and longer run times between backwash cycles. A sand-only filter filters particles to about 20-25 microns in size, and a multi-media filter to about 10-20 microns.

    Water Tech coagulants can also be applied upstream of a filter to improve removal of very fine particles through “direct filtration” or "agglomeration".

    Water Tech also supplies pre-engineered multi-media filter tanks and systems in all sizes.

  • Calcite Media pH Neutralizer

    Economical Distribution System Corrosion Control

    Water Tech Calcite is a naturally occurring, white marble calcium carbonate media used to neutralize acidic or low pH water such as reverse osmosis (RO) permeate, increase pH and reduce corrosion. One advantage of Calcite is that when properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces distribution system corrosion and the potential leaching of copper, lead and other metals found in plumbing systems.

    General Operating Conditions:

    • Gravel support bed recommended
    • Water pH range: 5.0-7.0
    • Bed depth: 24-30 in.
    • Freeboard: 50% of bed depth (min.)
    • Backwash rate: 8-12 gpm/sq. ft.
    • Service flow rate: 3-6 gpm/sq. ft.

     

    Water Tech also supplies pre-engineered calcite filter tanks and systems in all sizes.

  • Ion Exchange (IX) Resins

    Dow Dowex, Amberlite, Purolite, Alamo, and Other Resins

    Ion exchange (IX) is the exchange of ions between a solid substance called a resin, and an aqueous solution such as potable, boiler feed, or industrial process water, to control water purity and pH by removing undesirable ions and replacing them with acceptable ones.

    Cation exchange resins exchange and remove positive ions such as calcium (Ca+2) and Magnesium (Mg+2) hardness, Fe+2, and H+1. Anion exchange resins exchange and remove negative ions such as alkalinity, Cl-1, SO4-2, and OH-1.

    Our world-class Dow Dowex, Amberlite, Purolite, Alamo, and other ion exchange resins serve applications as diverse as industrial water softening and demineralization, pharmaceuticals, sweetener purification, mining and more. Our ion exchange resins come in a variety of chemical compositions, polymer structures, and particle sizes to meet current and developing industry needs and requirements.
