Biokinetic Constants: heterotrophic_bod
Biokinetic constants for biological wastewater treatment design — Monod kinetics parameters (mu_max, Ks, Y, kd, fd, theta) by organism/substrate type
| organism substrate | parameter id | notes | parameter name | temperature basis degC | unit | value max | value min | value typical |
|---|---|---|---|---|---|---|---|---|
| heterotrophic_bod | kd | Classical net kd. ASM1 b_H=0.3-0.62 1/d includes lysis+regrowth (death-regeneration); not interchangeable with classical kd. | Endogenous decay coefficient | 20 | 1/d | 0.2 | 0.06 | 0.1 |
| heterotrophic_bod | ks | COD-basis: ASM1 K_S=10 mg COD/L. BOD-basis values higher because BOD is a fraction of COD (~0.6-0.7). | Half-saturation constant (BOD basis) | 20 | mg BOD/L | 100 | 10 | 40 |
