Abstract
Alcohol distillery biodigester effluent subjected to Aspergillus sp. (MD-1) treatment had a 77% efficiency of color reduction after five days of incubation. The pH decreased to 2 and chemical oxygen demand (COD) removal was 74%. Ozonation of the effluent yielded 52% decolorization after six hours of treatment A slight increase in pH from 8.7 to 8.9 was observed. However, there was no observable COD removal. The combined treatment of microbial-ozonation had a decolorization yield of 87% while ozonation-microbial had 76%. This was significantly different at 5% level of significance. Both of the treated effluents from the two set-ups exhibited a decrease in pH. On the other hand, no COD removal was observed in either treatment. Aspergillus sp (MD-1) treatment and ozonation were both effective in decolonzing the alcohol distillery biodigester effluent. Also, the sequential combination of microbial-ozonation treatment had a greater decolorization efficiency than ozonation-microbial treatment.
