The agricultural spreading of treated sewage sludge is a valid strategy in terms circular economy for the management this nutrient-rich waste. Anaerobic digestion (AD) can be applied to stabilize and hygienize sludge, making it suitable reuse, while producing biogas utilized as an energy vector. However, presence contaminants, including petroleum hydrocarbons, could limit widespread utilization...

Petroleum industries are large water consumers and generate a lot of wastewater at various stages industrial operations. Wastewater from the petroleum contain recalcitrant pollutants such as hydrocarbons that present in high concentrations, dissolved solids sulfur compounds can pose potential environmental threat. Bioelectrochemical systems (BESs) known to be sustainable processes treat kinds w...

Experimental assessment of process kinetic is essential for modelling and can serve as a useful tool to improve performance. In this study, evaluation petroleum refinery wastewater (PRWW) biodegradation in an activated sludge (ASP) was carried out 25 L ASP reactor which operated within the conventional aeration mode 2-10 hours, hydraulic retention time (HRT), effluents from secondary sedimentat...

The influence of the concentration total petroleum hydrocarbons (TPHs) on competition between isolated oil-degrading bacteria (ODB) and finished compost microorganisms (FCM) was investigated in composting bioreactors over 12 weeks period. First, batch tests were performed Bushnell–Haas medium (BHM) to evaluate biodegradation activities six native ODB from sludge (PS). Then, added containing 10 ...
