Biokinetic Constants: anaerobic_acetate
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 |
|---|---|---|---|---|---|---|---|---|
| anaerobic_acetate | kd | Low decay rate. ADM1 kd_ac=0.02 1/d. Min SRT = 1/(mu_max-kd) ~ 5.6 d; design SRT with SF 3-5x = 15-30 d. | Endogenous decay coefficient | 35 | 1/d | 0.04 | 0.01 | 0.02 |
| anaerobic_acetate | ks | Highly species-dependent. Methanosaeta Ks~30-50 mg COD/L (dominates at low acetate). Methanosarcina Ks~200-400 (dominates at high acetate). ADM1 K_S_ac=150. | Half-saturation constant (acetate as COD) | 35 | mg COD/L | 400 | 30 | 150 |
