Typical BMP TSS and TP removal rates from Minnesota Stormwater Manual
Link to this table
| BMP type | Typical pollutant removal rate (%) | |
|---|---|---|
| TSS | TP | |
| Biofiltration | 80 | [1] |
| Sand filter | 85 | 50 |
| Iron enhanced sand filter | 85 | 65 or 741 |
| Dry swale | 68 | [2] |
| Constructed wet ponds | 84 | 50 or 682 |
| Constructed wetlands | 73 | 38 |
| Permeable pavement | 74 | 41 |
| Green roof | 85 | 0 |
1Lower values are for Tier 1 design. Higher values are for Tier 2 design.
2Removal is for Design Level 2. If an iron-enhanced pond bench is included, an additional 40 percent credit is given for dissolved phosphorus. Use the lower values if no iron bench exists and the higher value if an iron bench exists.
