Bioremediation of Melanoidin Containing Industrial Effluent ? A Qualitative Laboratory Scale Study on ?Modified? Soil

K. K. Bandyopadhyay, Debarati Paul

Qualitative studies of colour removal of distillery effluent were carried out continuously in packed bed reactor to screen out the suitable combination of modified soil. The continuous reactor (voidage: 0.39-0.4, packed density: around 1) studies enable to remove colour and COD degradation of effluent (COD 22000-23000 mg/l) to the tune of 97-99% respectively for the period of more than 10 days. Formulation of modified soil, kinetic data, voidage, space velocity etc are important parameters in assessing the efficiently of the reactor performance.
