Abstract

Starch and dye wastes have wide variation in their characteristics were treated on combination; this new technology supports the effective utilisation of starch waste in destruction of dyes. In this investigation, a lab-scale two-phase HUASBR was used at ambient temperature. After start-up, the dye and starch effluent were mixed at different proportions and fed into the reactor. The reactor was operated with an OLR of 8 kg. COD/m³.d and HRT of 12 h. The high COD (96%), colour removal (97%) and a biogas generation of 24.5 l/d were achieved with a 40/60 ratio of dye and starch effluent.
