Calgon Carbon - Model 6 -Modular Carbon Adsorption System

The Model 6 system is delivered as two adsorbers and a separate compact center piping network, requiring only minimal field assembly and site connections. An optional platform skid is available to facilitate installation. The pre-engineered Model 6 design assures that all adsorption system functions can be performed with the equipment process design.

The process piping valve network for the Model 6 offers operation of the absorbers in parallel or series flow (with either adsorber placed in the lead stage).The piping valve network can also isolate either adsorber from the process flow. This permits carbon exchange or backwash operations to be performed on one adsorber without interrupting treatment.

The under-drain design provides for the efficient collection and uniform distribution of treatment water and the uniform distribution of backwash water. The Model 6 system is designed for use with Calgon Carbon`s closed loop carbon exchange service. Using specially-designed trailers, spent carbon is removed from the adsorbers in a closed loop and returned to Calgon Carbon for reactivation. The transfer is accomplished without exposure of operating personnel to contaminated liquid. The trailers also recharge the adsorbers with fresh activated carbon.

Carbon Adsorbers

• Carbon steel ASME code stamped pressure vessels
• Internal vinyl ester lining (25-35 mils) to protect carbon steel surfaces
• Suitable for potable water and most liquid applications
• Internal underdrain with stainless steel slotted septa for water collection and backwash distribution

Standard Adsorption System Piping

• Schedule 40 carbon steel piping with cast iron fittings
• Cast iron or steel wafer butterfly valves in process piping
• Polypropylene lined steel pipe for carbon discharge pipe
• Full bore stainless steel ball valves for carbon fill and discharge piping
• Pressure gages to measure pressure drop across system and each adsorber
• Rupture discs open to each vessel for emergency pressure relief

System External Coating

• High solids epoxy paint system

Typical System Options

• In-bed water sample collection probes
• System skid (shipped separately), upon which system components can be assembled
