Biological treatment becomes ineffective for the wastewater containing refractory COD and high TDS. Advanced Oxidation processes have been recommended for the treatment of such wastewater. However, the removal efficiency for COD is very less and also generates huge amount of sludge. FACCO technology developed by CLRI employs Iron impregnated mesoporous activated carbon. Hydrogen peroxide is applied as the inducer of hydroxyl radical and the production of hydroxyl radical is sustained from molecular oxygen, abstracted from air. This facilitates the oxidation of refractory organics in wastewater at low detention period. FACCO technology has been implemented for the treatment of wastewater discharged from industrial sector such as leather, textile, chemical, pharmaceutical, food etc.
