Treatment equipment
MEDIA
Chemical media and dry filtration — Select reactive adsorption media or multi-stage media combinations according to the chemistry of the target odor compounds.
Operating limits
Media type, bed depth, contact time, humidity and replacement criteria must be designed for the operating conditions rather than selected by cabinet size alone.
System combinations
Applications include waste storage, laboratories, animal facilities, small wastewater sources and polishing after other treatment stages.
PROCESS & OPERATION
Identify the compound. Then select the media.
Dry chemical filtration uses targeted media combinations for acidic, alkaline and other suitable odor compounds. Selection depends on concentration, humidity, contact time and servicing requirements.
Explore testing & validation ↗- 01
Identify the gas
Define target compounds, concentrations and interfering substances.
- 02
Match the media
Select individual or staged media by reaction and adsorption behavior.
- 03
Design the bed
Coordinate face velocity, bed depth, pressure drop and bypass sealing.
- 04
Track condition
Use outlet measurements and media assessments to plan replacement.
Targeted treatment
Evaluate sulfur, nitrogen and acid compounds separately instead of selecting media by smell alone.
System role
Use as a standalone stage or for polishing after upstream treatment.
Maintenance access
Allow space for sampling, media replacement and safe handling during selection.
