Co-fermentation of waste activated sludge with food waste for short-chain fatty acids production: effect

Leiyu FENG, Yuanyuan YAN, Yinguang CHEN

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 4,   Pages 623-632 doi: 10.1007/s11783-011-0334-2

Abstract: pH ranging from 4.0 to 11.0 on co-fermentation of waste activated sludge (WAS) with food waste for short-chainfatty acids (SCFAs) production at ambient temperature was investigated in this study.The SCFAs production at pH 6.0, 7.0, 8.0, and 9.0 and fermentation time of 4 d was respectively 5022.7The composition of SCFAs at pH from 6.0 to 9.0 was also different from other conditions and propionicacid was the most prevalent SCFA, which was followed by acetic and n-butyric acids, while acetic acid
