Airflow & Bed Sizing
Convert enclosure volume and air-change assumptions into design airflow, or use a direct airflow input. Determine biofilter bed area, media depth, and rectangular bed dimensions.
Engineering Excel Workbook
Odor Control Biofilter Design Calculation
Size a packed-bed biofilter for preliminary odor control using a structured Excel workbook. Determine design airflow, bed area and media volume, and evaluate empty bed residence time, H₂S mass loading, elimination capacity, and selected operating criteria.

What This Module Helps You Design
H₂S Loading Evaluation
Estimate H₂S mass loading from gas concentration and airflow, and compare the pollutant loading with the adopted elimination capacity.
Operating & Design Review
Evaluate empty bed residence time (EBRT), surface and volumetric loading, selected media conditions, estimated back pressure, and buffer requirement.
Calculation Coverage
A linked preliminary design workflow from ventilation requirements through packed-media sizing, H₂S mass-loading screening, and operating checks.
Design Airflow & Biofilter Sizing
- Room volume, air changes per hour, or direct airflow override
- Selected surface loading rate and media depth
- Required packed-bed area and media volume
- Rectangular biofilter width and length
Hydraulics & Media Operation
- Empty bed residence time (EBRT)
- Residence time based on adopted media porosity
- Surface and volumetric air loading
- Media moisture, pH, and estimated back pressure
H₂S Loading & Preliminary Review
- H₂S concentration conversion and mass loading
- Adopted elimination capacity and media-volume screening
- Outlet H₂S estimate from target removal assumption
- Indicative buffer requirement and design-status checks

Built-in Design Checks
Review the preliminary packed-bed sizing and operating basis against the selected project criteria.
| Review Item | Workbook Evaluation |
|---|---|
| Air surface loading | Review selected surface loading against the adopted operating range |
| Volumetric loading & EBRT | Evaluate airflow relative to media volume and empty bed residence time |
| H₂S elimination capacity | Compare estimated H₂S mass loading against the adopted media elimination capacity |
| Media operating conditions | Check selected media moisture content, pH, and operating assumptions |
| Estimated back pressure | Screen the assumed biofilter pressure drop against the design limit |
These checks are preliminary. The displayed outlet H₂S concentration is derived from the user-selected removal target, not an independently validated biological kinetics model. Confirm contaminant loading, packing performance, blower requirements, irrigation, and buffer demand with project-specific data.
