- •
Biogas production from slaughterhouse wastewater treatment is optimized.
- •
Statistical models were developed for biogas production and TOC, TN, and TSS removal.
- •
Optimum conditions found at 343 mgTOCin/L, feed flow rate of 63 mL/min, and pH of 6.84.
- •
Maximum TOC and TN removals of 85.03 and 72.10% were found at optimum conditions.
- •
Biogas yields of up to 116.56 mL/min were found at optimum conditions.
