- •
Optimal pH range of anaerobic hydrogen production from dairy processing waste (DPW) was 4.8–5.5.
- •
Thermophilic digestion can gain higher hydrogen yield and suppress the growth of methanogens.
- •
Optimum DPW loading rate was 32.9 g-COD/l-d at hydraulic retention time (HRT) of 3 days for hydrogen production.
- •
Two-stage induced bed reactors (IBR) produced mixed gas with higher heating value and COD removal than single-stage.
