TREATMENT OF A TEXTILE DYE IN THE ANAEROBIC BAFFLED REACTOR

Experimental decolorisation of the dye CI Reactive Red 141 of a South-African textile wastewater in a laboratory-scale anaerobic baffled bioreactor (ABR) by adsorption to the biomass. The dye chromophores were possibly reduced due to the low redox potential within the test bottles. COD reduction was consistently over 90% and colour reduction averaged 86%.
