Biokinetic Constants: denitrifying_nitrate
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 |
|---|---|---|---|---|---|---|---|---|
| denitrifying_nitrate | kd | Similar to aerobic heterotroph decay; slightly lower under anoxic conditions. ASM1 uses same b_H for aerobic and anoxic. | Endogenous decay coefficient | 20 | 1/d | 0.15 | 0.04 | 0.08 |
| denitrifying_nitrate | ks | ASM1 K_NO=0.5 mg/L. Post-denitrification systems may show higher Ks (2-3.5 mg/L). Pre-denitrification typically lower. | Half-saturation constant (NO3-N) | 20 | mg NO3-N/L | 2.5 | 0.1 | 0.5 |
