The present invention provides treatment of pH corrected undiluted colored effluent with the fungal biomass of Aspergillus oryzae for decolorization and reduction of BOD, COD and TDS ftom the effluent aid the treated effluent can be recycled for the industrial need or disposed off as required. The reduction of eolor and other parameters like BOD, COD and TDS of the effluent takes place by simple adsorption technique. The fungal biomass of Aspergillus oryzae is used till the saturation level of the fungal cells for adsorption and the saturated biomass is reused after conducting standard regeneration processes such as treatment with heat, alkali wash and acid wash. After the complete exhaustion of the capacity of the biomass, the biomass in the form of sludge is used as manure after composting or disposed off as required. Thus the present invention provides a safe, economical, compact, easy to use and eco-fiiendly solution to the burning problem of treatment and disposal of colored industrial effluents like distillery, textile, paper and pulp (black liquor) and tannery effluents. |
