Medium-chain fatty acids (MCFAs) represent a promising form of energy recovered from waste activated sludge (WAS) through anaerobic fermentation. However, the low WAS degradability hindered MCFAs generation WAS. In this study, urine pretreatment 5 – 25 wt% was applied to enhance production in anerobic fermentation with ethanol as an electron donor. Urine (5 wt%) dose-dependently improved by 0.8 3.3 times (from 2.4 4.4 12.8 g chemical oxygen demand (COD)/L) and enhanced selectivity 3.5 12.2 % 21.4 54.4 %). degradation up 54.8 transfer efficiency substrates (i.e. ethanol) 18.6 %, which contributed improvement production. According model-based analysis, potential (Pm) rose 2.71 ± 0.09 COD/L 0 4.51 13.11 pretreatment, while lag phase (λ) decreased 5.30 d 4.67 3.08 d, may be reason for Additionally, significantly facilitated each step involved generation, i.e. solubilization, hydrolysis, acidification, chain elongation, 600 51 17 42 respectively. This study first time reported innovative method, enhances recovery fermentation, potentially brings wastewater treatment plants economic environmental profits.
