The DEEP BED OCS line of FRP odor control systems are designed to be a low cost, highly effective system for removing H₂S and other odors from municipal wastewater applications. The systems can utilize a wide variety of absorbent medias and mixtures for the specific treatment needs. The DEEP BED OCS system provides the following benefits:

 

Ø  Lower Capital Cost than Caustic Scrubber or, Biofilters

Ø  No chemical usage or storage required

Ø  High Efficiencies of H₂S and organic odor removal

Ø  Smaller footprint than Biofilters

Ø  High Reliability

Ø  Low maintenance or operator intervention required

Ø  Flexibility, due to wide range of available options which allows customization

Ø  Ease of installation

Ø  Excellent corrosion resistant properties for long service life.

Ø  Can utilize a wide variety of media and mixtures of media for specific treatment needs

 

PROCESS DESCRIPTION

 

The DEEP BED OCS utilizes two basic designs as shown below. For single bed systems, the air enters the bottom and travels upward and is diffused through the media bed and exists the top. For dual bed systems, the air enters the center of the vessel and travels upward and downward and diffuses through both beds. The upward flow exits through the top and the downward flow exits through a collection duct that runs from the bottom through both beds and out the top. Both effluent stacks can be then ducted together for discharge.

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 few valves. The water regeneration system is comprised of water connections on the vessel bottom and top. 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).

 

SERVICEABILITY

 

The system is serviced by removing the manway. The media can then be removed if saturated and the media support screen can be inspected and replaced if required.
