The proposed research intended to acquire the perception of proficient biomethane generation enhanced by TiO2 embedded chitosan thin film (TCTF) mediated enzyme secreting bacterial pretreatment of sludge. Impregnates 0.05 g/g SS TiO2 dosage on chitosan solid matrix effectively disperse sludge flocs and induces deflocculation of 99.35%. This TCTF enhances the enzyme secreting bacterial disintegration by increasing the hydrolytic activity. A higher solubilisation of 16% achieved in TCTF mediated bacterial disintegration while related to enzyme secreting bacterial disintegration alone. The high specific growth rate of 0.2 h−1 for enzyme secreting bacterial growth rate is attained at 42 h. Deflocculation and enzyme secreting bacterial pretreatment has a major impact on methane potential assay. The sludge sample TCTF mediated bacterial disintegration yields 140.40 mL/g COD higher methane than the other samples. The energetic and cost analysis of the proposed work confirms the feasibility of this sludge management process having profitable net cost of 89.92 USD/Ton of sludge.
