The SPARROW line of up flow odor control systems is designed around a modular, prefabricated plastic (FRP optional) canister for removing H2S and other compounds odorous or VOCs from municipal wastewater applications. These systems can utilize a wide variety of absorbent medias for specific treatment needs. The SPARROW system provides the following benefits:

• Lower Bapital Cost than Caustic Scrubbers, Biofilters, or Deep Bed systems
• Lower Operating cost than Deep Bed systems
• High Efficiencies of H2s and organic odor removal
• Samll Footprint
• High Reliability
• Low maintenance or operator intervention required
• Complete skid mounted unites up to 3,300 cfm thus reducing installation and construction costs.
• Can utilize a wide variety of media and mixtures of media for specific treatment needs

The SPARROW system also comes with several standard add-on options for:

• Regeneration Package for regenerable carbon media
• Sequential vessels for ammonia or other component removal
• Neutralization of acidic regeneration stream

SERVICEABILITY

One of the unique benefits of the HAWK design is the ease to perform media replacement. It is as simple as disconnecting the inlet duct and removing the flanged 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

PROCESS DESCRIPTION

The SPARROW utilizes up flow operation with the foul air entering from the bottom and is then diffused through the media bed. The H2S (or other contaminates) are then removed and the clean air is collected at the top portion of the vessel and exits the exhaust stack.

For regenerable medias, once the system is saturated with H2S it is taken off-line and is regenerated with water. The regeneration process is as simple as turning a couple valves. The water regeneration system is comprised of water connections on the vessel bottom and inlet duct. The water is run and is discharged until vessel is cleaned. Then a bottom drain valve is opened to drain the remaining water from the system. This process can be continued for many regeneration cycles until the vessel media activity is greatly reduced (usually two years).
