The New Era in Odor Control Systems

The HAWK line of radial flow odor control systems are designed to be a low cost, highly effective system for removing H₂S and other compounds from municipal wastewater applications. These systems can utilize a wide variety of absorbent medias for specific treatment needs. The HAWK system provides the following benefits:

• Lower capital cost
• Lower operating cost than Deep Bed or up flow canisters
• High efficiencies of H₂S and organic odor removal
• Small footprint
• High reliablity
• Low maintenance or operator intervention required
• Reduced chance of short circuiting or channeling (unified face pressures)
• Low pressure drop thus lower horsepower blowers
• Can utilize a wide variety of media and mixtures of media for specific treatment needs

Serviceability

One of the unique benefits of the HAWK design is the ease to perform media replacement. It is as simple as opening spin-off manways in the lid. This allows access to the entire media bed. Furthermore, it allows you to inspect the entire screen surface or remove it without entering the vessel unlike Deep Bed systems. The system can be designed for complete media support/retention system removal without entering system.

Process Description

The HAWK utilizes radial flow operation with the foul air entering from the center or outside and is then diffused through the media bed. The H₂S (or other contaminates) are then removed and the clean air is collected in the outer portion of the vessel and exits the exhaust stack.

Standard Features & Options

All HAWK systems come with simple standard components that are readily available for ease of operation and maintenance:

Standard Features:

• FRP vessel

Standard Sizes

The HAWK system is built around standard design but custome sizes to allow exact size (height and diameter) needed for the specific applications for flows up to 30,000 cfm.
