ABSTRACT: This study was to examine the optimum Hydraulic Retention Time (HRT) for POME fermentation to achieve high Volatile Fatty Acids (VFAs) production. Two sets of POME fermentation (with and without Sodium Dodecylbenzene Sulfonate (SDBS) addition) were conducted. Each set composed of four lab-scale anaerobic digesters operated with HRTs of 6, 15, 30 and 60 days, respectively. In case of no SDBS addition, the highest VFA yield of 0.28 mg/mg ...
