Enhancing Anaerobic Digestion of Pharmaceutical Industries Wastewater with the Composite Addition of Zero Valent Iron (ZVI) and Granular Activated Carbon (GAC)

Enhanced methane production by granular activated carbon: A review

“…For example, the use of GAC in the treatment of highstrength organic wastewater increased the removal efficiency of N-heterocyclic compounds, acids and aromatic compounds to more than 95% [84]. Dai et al showed that GAC composite increased 11% methane production during pharmaceutical wastewater treatment and enhanced the pharmaceutical intermediates degradation [85]. At present, it is not clear which role is the more important, adsorption or DIET.…”

“…The modification of GAC with other materials also promoted the degradation of toxic compounds. Dai et al demonstrated that GAC/ Zero-Valent-Iron composites increased the degradation of complex pharmaceutical wastes [85]. Cheng et al showed that adding GAC and ZVI together increased the pentachlorophenol removal efficiency by 50% and methane production by 15% [106].…”
