Biofilm carrier options
HDPE carriers are available in several geometries for moving-bed biological treatment. Select media dimensions and quantity together with the process design, mixing conditions and retention-screen openings.
Catalogue examples
- PE01: 12 × 9 mm, 4 holes, HDPE
- PE04: 16 × 10 mm, 6 holes, HDPE
- PE05: 25 × 10 mm, 19 holes, HDPE
- PE64: 25 × 4 mm, 64 holes, HDPE
Dimensions are catalogue references; final media grade, fill fraction and treatment performance require project-specific confirmation. Photographs show product examples, not a performance guarantee.
Compare carrier geometries
| Model | Size (mm) | Holes | Surface area (m²/m³) |
|---|---|---|---|
| PE01 | Ø12 × 9 | 4 | >800 |
| PE04 | Ø16 × 10 | 6 | >800 |
| PE05 | Ø25 × 10 | 19 | >600 |
| PE64 | Ø25 × 4 | 64 | >1,200 |
| PE85 | Ø36 × 4 | 85 | >1,200 |
These examples use HDPE with catalogue density 0.94–0.97 g/cm³. The catalogue labels the figures “surface area”; they should not be treated as verified protected surface area. Media fill and aeration/mixing requirements are selected with the process designer.
