Abstract
The long-term monitoring on an anaerobic digestion of cassava starch wastewater (CSW) using completely stirred tank reactor was performed for more than 260 days. The optimum operating organic loading rate (OLR) was 2.58 kg COD/m3/d with pH, total volatile fatty acid (VFA) concentration, and VFA/alkalinity of 6.95±0.10, 618.30±37.30 mg/L as acetic acid, and 0.28±0.09, respectively. However, the reactors showed the signs of failure when operated at the final OLR of 2.96 kg COD/m3/d. The pH significantly dropped resulting from accumulating VFA in the system. At the operating OLR of 2.58 kg COD/m3/d, oxidation reduction potentials of the systems were in the effective range of methanogenesis stage. Total chemical oxygen demand and volatile solid removal were high as 80.85±1.37%, and 79.32±2.93%, respectively. Methane yield was reported to be 0.48±0.04 NL/gVSadded. Finally, the failure reactors were recovered, and the results could confirm the optimum operating OLR of 2.58 kg COD/m3/d. Anaerobic co-digestion between starch wastewater and high-nutrient substrate could enhance the efficiency of the system. In addition, the biorefinery technology to produced high value bioproducts such as bioplastics and to use in biological nutrient removal process might be appropriate challenges to enhance the economic viability of the AD of CSW.
