Project in Brief
- Project Name: Headworks Bar Screens Project
- Location: Hayward, CA
- Installation Date: May 2020
- Source of Odors: Scrubber Beds
- System Type: Biofilter
- Media Type: Crater-Max®
- H2S Removal Efficiency: >99%
The Situation
Two separate biofilter cells (25'-0" wide x 50'-0" long x 6'-0" deep) at the new Headworks Bar Screens Project required the installation of odor control media.
The Solution
Both Biofilter beds were installed with GES Biotek Crater-Max® media to a depth of 6 feet. Within a Biofilter, Crater-Max® media serves as part of the ecosystem for the growth of acidithiobacillus thiooxidans microorganisms. The porous Crater-Max® media also contains the necessary iron content that in a low pH environment will create a chemistry of iron ions to support a colony of acidithiobacillus ferroxidans microorganisms. The media surface openings are not through-and-through, therefore eliminating any increase in static pressure over time due to fouling of the pore structure. New irrigation spray nozzles were installed on both beds as well.
A smoke test and full performance test verified that the newly outfitted system was performing to spec. The smoke tests demonstrated uniform airflow distribution throughout the Crater-Max® media bed on both the side-by-side biofilter cells which indicates that the air distribution has even airflow pattern at both of the biofilter cells.
