ABSTRACT
An attempt has been made to present the data relating to full-scale application of evaporation incineration technology for containment of wastewater emanating from H-acid (mono sodium salt of 1 amino-8-hydroxynapthalene 3,6-disulphonic acid) production with recourse to zero wastewater discharge. The wastewater is acidic with high concentrations of COD and total dissolved salts and BOD/COD ratio of 0.09-0.11. NOx SOx, SPM and CO from stack emissions are within the standards stipulated by the statutory bodies.
