The Ideal

The valorization of agro-modern waste through anaerobic codigestion signifies a remarkable prospect for waste treatment and sustainable energy source generation. This study intended to improve the codigestion of food waste and petrochemical wastewater by an advanced two-phase process. In view of concentric acidogenic and methanogenic stages, intended for upgrading execution and diminishing pollution. The ideal food waste to petrochemical wastewater proportion was assessed under batch operations. From that point, codigestion was carried out by continuous feeding operations weighting single-and two-phase digestions. The outcomes exhibited that the supplementation of petrochemical wastewater in codigestion with food waste incredibly improved the anaerobic system. The maximum methane generation was acquired codigesting the two wastes at equivalent proportion by utilizing the creative two-phase system. The proposed framework achieved the highest methane production of 259 mL/g volatile solid, which is more than double than the single-phase system and 11 % greater than that of conventional two-phase system.

Thermophilic Condition

The effect of gradual increase in organic loading rate (0LR) and temperature on biomethanation from petrochemical wastewater treatment was investigated using CSTR. The digester performance measured at hydraulic retention time (HRT) of4 to 2d, and start up procedure of the reactor was monitoredfor 60 days via chemical oxygen demand (COD) removal, biogas and methane production. By enhancing the temperature from 30 to 55 “C Thermophilic condition was attained, and pH was adjusted at 7 i 0.5. Supreme COD removal competence was 98i0.5% (r = 0.84) at an 0LR of 7.5 g-COD/Ld and 4d HRT. Biogas and methane yield were logged to an extreme of 0.80 L/g-CODremoved d (r = 0.81), 0.60 L/g-CODremoved d (r = 0.83), and mean methane content of biogas was 65.49%. The full acclimatization was established at 55 C with high COD removal efficiency and biogas production. An 0LR of 7.5 g-COD/L d and HRT of 4 days were apposite forpetrochemical wastewater treatment.

Generation Capacity

With the target of amplifying methane generation from sewage sludge (SS), co-digestion with petrochemical wastewater (PWW) was examined. In addition, the use of both 165 °C heat treatment and alkali pretreatment to mixed SS/PWW wastewater was assessed. Batch tests demonstrated that refractory materials were generated from pretreatment for petrochemical wastewater at the 165 °C heat and alkali pretreatments at the 75 or 115 °C and with pH value of 8, 9 or 10 producing enhanced preliminary methane generation percentage and a little effect for generation capacity of methane of the miscellaneous waste (+3–6 %). Anaerobic reactors which were operated more than four months semi-continuously with sewage sludge and petrochemical wastewater mix with the proportion of 85:15, 55:45 and 85:15 pretreated at alkaline environments maintaining the temperature of 75 °C and pH = 8. This pretreatment enhanced the production of methane at semi-continuous anaerobic reactors to + 59 %. Finally, this investigation demonstrated the viability of the co-digestion of sewage sludge with a higher ratio of petrochemical wastewater [45 % volume, 50 % volatile solid (VS) and 74 % COD, comparable with volatile fatty acids of 8 g L–1]. The system produced an exact methane of 363 mL CH4 g–1 VS while only sewage sludge generated 117 mL CH4 g–1 VS.
