Packed Bed System (PBS)

Packed Bed System (PBS) Case Studies

FACILITY TYPE: Ankeny Wastewater Pump Station

LOCATION: Portland, Oregon

EQUIPMENT/MEDIA USED: 2 – Packed Bed System (PBS-709) and CPS Blend media

PROBLEM: The downtown park, a heavily used event area, is affected with odorous air, which cannot be removed without installing air filtration systems in an underground vault accessible only through a small service hatch.

SOLUTION: PureAir® custom engineered two PBS systems, cut each system into 12 precise pieces, lowered them by crane through the hatch, maneuvered each piece down a narrow corridor, and reassembled both systems in the vault over the course of two to three weeks.

FACILITY TYPE: CSO Sewage Facility

LOCATION: Spokane, Washington

EQUIPMENT/MEDIA USED: Packed Bed System (PBS) and Sulphasorb XL™ media and CPS Blend media

PROBLEM: Processing raw sewage releases H2S, VOCs, mercaptans, and sulfur compounds into the air.

SOLUTION: PureAir® custom engineered multiple PBS systems (sizes ranged from PBS-404 to PBS-809) with two media beds in each for Sulphasorb XLTM media and CPS Blend media.
