Treating petrochemical wastewater is a challenge for conventional anaerobic reactors. One example coal gasification that, besides its salinity, rich in toxic and inhibitory aromatics, such as phenol, cresols, resorcinol. Studies have shown that phenol p-cresol share the same degradation intermediates, whereas resorcinol degraded via another route. This study investigated simultaneous of or with under saline conditions. Batch experiments phenol-degrading biomass were conducted to assess...
Phenol conversion under saline thermophilic anaerobic conditions requires the development and sustenance of a highly specialized microbial community. In present research, an membrane bioreactor (AnMBR) fed with influent containing 0.5 g·L−1 phenol 6.5 gNa+·L−1 was operated at 55 °C for 300 days. degradation limited when sole substrate. However, removal efficiency significantly (p < 0.001) increased to 80 % corresponding rate 29 mgPhenol·gVSS−1d−1 acetate (0.5 gCOD·L−1) simultaneously...
Phenolic industrial wastewater, such as those from coal gasification, are considered a challenge for conventional anaerobic wastewater treatment systems because of its extreme characteristics presence recalcitrant compounds, high toxicity, and salinity. However, membrane bioreactors (AnMBRs) potential interest since they retain all micro-organism that required conversion the complex organics. In this study, degradation phenol main carbon energy source (CES) in AnMBRs at salinity (8.0 g Na +...
Closing water loops in chemical industries result hot and highly saline residual streams, often characterized by high strength the presence of refractory or toxic compounds. These streams are attractive for anaerobic technologies, provided compounds biodegradable. However, under such harsh conditions, effective biomass immobilization is difficult, limiting use commonly applied sludge bed reactors. In this study, we assessed long-term phenol conversion capacity a lab-scale membrane bioreactor...
Bitumen fume condensate (BFC) is a hazardous wastewater generated at asphalt reclamation and production sites. BFC contains wide variety of potentially toxic organic pollutants that negatively affect anaerobic processes. In this study, we chemically characterized produced an industrial site evaluated its degradation under conditions. Analyses identified about 900 compounds including acetate, polycyclic aromatic hydrocarbons, phenolic compounds, metal ions. We estimated the half maximal...
Vinasse, a by-product of ethanol production, is generated at significant rates. While rich in nutrients such as calcium, magnesium, and potassium, its high solids, organic matter, acidity, sulfate content pose challenges when disposed directly on soil, necessitating treatment. Anaerobic digestion viable solution, reducing pollution while recovering energy the form biogas, aligning with biorefinery concept. Traditionally, sludge bed reactors anaerobic contact are utilized for vinasse...
Vinasse is a by-product of sugarcane processing which often used in fertigation; however, the direct use vinasse harms environment and reduces soil productivity due to its physicochemical properties. Anaerobic digestion (AD) offers an alternative mitigate part negative effects. high-rate reactors, mainly rely on sludge granulation, are mostly AD wastewater. However, composition such as high concentration solids organic matter, salinity, low pH, concentrations sulfate, affect granule...
