(with different melamine concentrations) by high temperature calcination method. The co-existence of C

and visible light activity was confirmed by XRD, TEM, UV-visible and PL spectroscopy. The photocatalytic performance of TiO

was achieved at optimum pH 7.0 and pollutant load of 30 mg/L. The application of C

NTs for solublization of rigid
structure of sludge by photocatalysis released the soluble organics showing an improvement in sCOD production (4587 mg/L).
Subsequently, anaerobic digestion of solubilized sludge has improved the methane production (723.4 mlkg

VS) by 1.37 and 1.6
times compared to that in anaerobic digestion with photolytic and raw sludge, thus showing a promising applicability for biogas
production from sludge.
