| Abstract |
A laboratory experiments were performed to investigate the effectiveness of pellets formed by Aspergillus niger on the treatment of wastewater containing high concentration of starch and glucose. Pellets were prepared by using pure culture in wheat bran media. The size of pellets formed became small as the pH of medium decrease. In batch experiments, starch was degraded within 0.5 hour and the glucose produced from the starch decomposition was degraded. The glucose production decreased with increasing cell concentration in the range of 5 × 10^5 to 15 × 10^5 spores/㎖. During the continuous experiments, the total COD and starch removal rate were 94% and 100% at the HRT of 12 hours in the fungal pellets reactor conbined with activated sludge reactor when both synthetic and ice cream wastewater were used. The glucose produced from the starch decomposition was degraded to 100% in this system. |
