Calgon Carbon - Dual Express - Carbon Adsorption System
Calgon Carbon`s Dual Express is a carbon adsorption system specifically designed to provide a rapid solution to a temporary problem. For emergency situations where quick response is critical, it can be dispatched to a customer`s site within hours of notification and operation can begin immediately after set-up. Calgon Carbon personnel are available to supervise system start-up.
The Dual Express is a skid-mounted backwashable system delivered as two pre-piped adsorbers with a separate interconnecting pipe module. It is available pre-filled with activated carbon that, once exhausted, can be returned to Calgon Carbon for reactivation as part of a closed loop carbon exchange service.
The Dual Express is ideal for periodic or temporary use where a permanent system would not be economical, including:
- Emergency wastewater treatment
- Cooling or process water purification
- Acid decolorization
- Alcohol purification
- Amine purification
- Immediate Availability
- Rapid Installation
- Versatile Design
- Closed Loop
- Cost Effective
- The Dual Express system is pre-piped and ready for shipment immediately without obtaining any special transportation permits.
- The Dual Express can be set up for operation and put on stream quickly.
- The Dual Express is designed to handle a wide range of flows and contaminants.
- Spent carbon may be returned to Calgon Carbon for thermal reactivation, eliminating the customer`s disposal concerns.
- Customer`s avoid incurring permanent capital expenses or maintenance costs because the Dual Express can be used as long as needed and then returned to Calgon Carbon.
