Simultaneous aerobic-anaerobic biodegradation of an industrial effluent of polymeric resins with high phenol concentration at different organic loading rates in a non-conventional UASB type reactor

High-Strength, Chemical Industry Wastewater Treatment Feasibility Study for Energy Recovery

“…As anaerobic metabolism is slower than aerobic metabolism, these processes generate low excess sludge production, simplifying its handling and disposal. For these reasons, anaerobic processes have been adopted in many circumstances for the efficient treatment of organic wastewater, even in non-optimal conditions [28][29][30][31]. A considerable number of technology reviews has been published on anaerobic industrial wastewater treatment, highlighting its benefits [32,33].…”

New Water Culture: Care, Sanitation and Reuse, for Social, Economic and Environmental Stability

“…And under these operating conditions of the system studied, a significant improvement in the phenol biodegradation efficiency (49%) is seen. To achieve adequate biodegradation efficiency of phenol from industrial wastewater through biological processes, it is recommended to acclimate the biomass of the biological reactor to the toxic compound to be biodegraded (Ba, Jones and Cabana, 2014;Terreros, Guzman and García, 2022). Under aerobic respiration conditions, phenol can be converted into a harmless compound (Ahmed, Rasul, Martens, & Brown, 2012).…”

“…This pathway has shown that there is a common metabolic route for this type of compound and even for those not so close to the family of phenolic compounds such as biphenyls (Autenrieth, Bonner, Akgerman, Okaygun, & McCreary, 1991). Where the acclimatization of any type of microorganism to the presence of phenol is a key factor (Terreros, Guzman and García, 2022). Various studies have been carried out to treat phenolic wastewater, due to the great contamination problem they represent, both for the environment, bodies of water, food and human health (Bevilaqua, Cammarota, Freire and Sant'AnnaJr 2002 ;Jiang, Tay and Tay (2004;Tay, Moy, Jiang and Tay 2005;Melo, Kholi, Patwardhan and D'Souza 2005;Hossein and Gordon, 2006;Bajaj, Gallert and Winter, 2008a;Contreras, Albertario, Bertola and Zaritzky, 2008;Donoso-Bravo, Rosenkranz, Valdivia, Torrijos, Ruiz-Filippi and Rolando, 2009;Ben-Youssef and Vázquez-Rodríguez, 2011).…”

Removal of Phenol from Sour Water by Poly(vinyl Alcohol)/Polyamide‐Reverse Osmosis Membranes

“…[7]. The concentration of phenol in wastewater (called before treatment sour water [8]) is from 0.1 to 80 000 mg L -1 [9].…”

“…Phenol has been classified as a priority pollutant by the United States Environmental Protection Agency (EPA) and the European Union, and these agencies set limits for wastewater discharge of 0.5 mg L -1 for surface water (mineral and drinking) and 1 mg L -1 for sewage water systems [9,10]. Since processed water is in close contact with hydrocarbons, it can be divided into four main groups: acidic water and process condensates, sewage desalination plants, tank bottoms, and spent caustic soda [11].…”
