Calgon Carbon - Dual Module Carbon Adsorption System

The Dual Module system is delivered to the site as two 10 foot diameter adsorbers mounted on a common skid, with each adsorber vessel capable of containing up to 20,000 lbs of granular activated carbon (GAC). The skid mounted adsorbers are equipped with process piping to facilitate two stage operation, and other utility and carbon transfer piping to provide for a complete system. The system requires minimal piping additions and support provisions in the field, which can be supervised by Calgon Carbon personnel. The carbon is delivered in Calgon Carbon`s bulk GAC delivery trailers for convenient slurry filling of the adsorbers.

When the carbon becomes fully utilized in service, the Dual Module adsorbers are designed for removal of the spent carbon and replacement with fresh carbon utilizing Calgon Carbon`s closed loop carbon exchange service. Using the specially designed trailers, the spent carbon is removed from the adsorbers minimizing contact with the spent media, and returned to Calgon Carbon for reactivation or disposal. The trailers are also used to recharge the adsorbers with fresh carbon to minimize downtime.

Versatility
The Dual Module utilizing activatedcarbon adsorption is effective for removing a wide spectrum of organic compounds, in high or low concentrations, and a wide range of flows.

Rapid Response
Dual Modules are pre-piped and "ready to go" on short notice, as quickly as 24-48 hours, to respond to your needs, even on an emergency basis.

Cost Effective
Calgon Carbon provides the equipment, activated carbon, and supervision for only as long as needed, avoiding permanent system purchases costs and ongoing maintenance.

Environmental Compliance
Carbon adsorption is a proven and flexible technology for treating contaminated groundwater, spills or lagoon wastewater, eliminating the threat to plant and animal life or potable water supplies, and meeting discharge requirements.

Carbon Adsorbers

• Carbon steel ASME code pressure vessels.
• Internal vinyl-ester lining (nominal $5 mil) for potable water and most liquid applications.
• Polypropylene (PPL) underdrain and slotted nozzles for water collection.

Standard Adsorption System Piping

• Schedule 40 3" or 4" PPL lined carbon steel process piping.
• Tetrafluorethylene (TFE) lined plug valves for process piping.
• PPL lined steel pipe for GAC discharge.
• TFE lined plug valves for GAC fill and discharge.

System External Coating

• Epoxy mastic or polyurethane paint system.
