Abstract |
This study aims to evaluate methods for removing suspended solids (SS) from tapioca starch wastewater in order to increase methane producing activity (MPA) and biochemical methane potential (BMP). Three methods for SS removal, including filtration, centrifugation, and settling, were compared with raw wastewater, which had a high SS concentration of over 3,000 mg/L. The filtration method was found to be the best method and was able to increase MPA by 44%while removing 100% of SS. Centrifugation and gravity settling had substantial effects, increasing BMP by 7.7% and 6.1% and removing 98.4% and 15.5%of SS, respectively. While SS concentration is the main factor for the successful operation of an up-flow anaerobic sludge bed (UASB) system, this study elucidated that the carbohydrate and protein ratio signifying the biochemical component of the wastewater is the key factor causing increases in MPA and BMP. The SS removal methods used in this study also led to higher carbohydrate/COD and protein/COD ratios, which can increase MPA and BMP values relative to conditions where SS removal is not performed. |
