| 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 0.11. NOx, SOx, SPM and CO from stack emissions are within the standards stipulated by the statutory bodies. |
