TWO GRADES OF GRANULAR ACTIVATED CARBON WHICH PROVIDE A COST EFFECTIVE SOLUTION FOR REMOVING TASTE, ODOR AND DISSOLVED ORGANIC CHEMICALS FROM PUBLIC WATER SYSTEMS

DESCRIPTION

Filtersorb 100 and 200 are two grades of granular activated carbon manufactured by Calgon Carbon for removal of
dissolved organic chemicals from municipal and industrial water suplies. Both are manufactured from select grades
of  bituminous coal to produce a high-density,durable granular product capable of withstanding and mechanical handling. Activation is carefully controlled to produce excepetionally high internal surface area with optimum pore
size for adsorption of a broad range of high and low moleculer weight organic contaminants.

PURPOSE

Filtrasorb activated carbons perform a dual function, filtration and adsorbing dissolved organic chemicals such as insecticides, detergents, phenols and other contaminants from both natural and industrial sources which cause taste, odor and color problems.

Filtrasorb activated carbons can be used to upgrade water quality using ex­isting rapid sand filtration equipment. Used as a complete replacement for sand or coal, they function as a dual
purpose medium: providing both filtration and adsorption. As a partial replacement for filter media, they can be used as an adsorbent to complement normal filtration processes. In either case, conver­sion to Filtrasorb imposes no changes to a plant’s normal filtration operations.

ADVANTAGES

  • Less handling-once Filtrasorb activated carbon is placed in the filter bed it requires no further handling until replacement.
  • Reactivation and reuse of granular activated carbon reduces treatment costs .
  • Improves water quality, taste, odor and appearance.
  • Reserve capacity provides safety margin against undetected    organic pollutants and accidental spills of toxic organic materials.

PACKAGING

Filtrasorb is packaged in five-ply kraft bags (SS lbs net, 56 Ibs gross). For less than one-ton quantities, each bag is packaged in a protective shipp­ing carton-Tare weight of carton-3 lbs. Available on 42″ x 48″ trailer­truck pallets, maximum 40 bags per pallet-20 pallets maximum for standard 40-foot trailer. Bulk shipments by truck 20,000 Ibs minimum; and by rail 50,000 Ibs minimum.

CAUTION

tabel_11 tabel_21

Wet activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, ap­propriate sampling and work procedures for potentially low-oxygen spaces should be followed, including all applicable Federal and State re­quirements.

Granular Activated Carbon For Water Treatment

Activated carbon perform a dual function, filtration and adsorbing dissolved organic chemicals such as insecticides, detergents, phenols and other contaminants from natural and industrial sources which cause taste, odor and color problems.
Activated carbons can be used to upgrade water quality using existing rapid sand fiitration equipment. Used as a complete replacement for sand or coal, they functions as a dual purpose medium providing both filtration and adsorption. As a partial replacement for filter media, they can be used as an adsorbent to complement normal filtration processes.

Very large water treatment plants, or plants confronted with exceptionally high contaminant loading, may wish to Investigate the economic feasibility of carbon reactivation. In most municipal and industrial applications, however, operating experience Indicates that life of the original bed ranges from 3 to 5 years for taste and odor control and reactivation is not currently employed.

CAUTION

Wet activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low oxygen spaces should be followed.
