Abstract: | Discharge of colored industrial efflu ent i.n water str ea msor on to the land is a matter of great concern as it is firstperception to be noticed by th e receptor. Molasses basedalcohol produ c in g di st ille ri es ge nerate characteristicallydark brown co lor due to th e presence of rn elanoidinpigment which is not only th e ca use of aestheticaldispleasure but also hav in g harmful consequen ce due to itsrecalcitrant nature. In the pr ese nt study, we did the initialcharact er ization followed by batch mode studi e u ingactivated carbon and Aspergillus niger to decolori zeanaerobically dige s ted MSW. We found thatdecolorization efficiency of activated wood saw dust wasup to 99 %, at adso rbent do sage of 5g/l 00 ml of effluent,pH 7, and contact time of30 minutes at room temperature.Wberea A. nig er s how ed its ability to d eco lorizeanaerob ic a ll y di gested MSW up to 71 % at day 4, wheneffluent was diluted at th e rate of 50 %, supplemented withextern al carbon (3% gluco e) and phosphate source (0.1%K 2HP04) |
