Enhanced biodegradation of phenolic wastewaters with acclimatized activated sludge – A kinetic study

“…Acclimatization can give rise to enhanced biomass populations which could be adapted to toxic compounds [34]. Acclimatization of activated sludge towards increasing phenol concentrations, including 50 mg/L (days 1-3), 100 mg/L (days 4-6), 200 mg/L (days 7-12), 300 mg/L (days 13-18), 400 mg/L (days [19][20][21][22][23][24], 500 mg/L (days 25-30), 600 mg/L (days 31-36), 700 mg/L (days 37-42), 800 mg/L (days [43][44][45][46][47][48], 900 mg/L (days 49-54) and 1000 mg/L (days 55-60) was carried out using a cylindrical reactor with an operating volume of 5 L under batch 3 mode. The initial phenol concentrations were determined based on a primary literature review [28,[35][36][37][38][39][40][41].…”

“…[5,18] and biological methods (e.g., fungal treatment, aerobic treatment, anaerobic digestion, etc.) [19][20][21][22][23] have been developed and applied so far for the treatment of industrial effluents and have shown various efficiencies for the degradation or removal of phenolic compounds [24]. Among the conventional methods for the treatment of industrial effluents, activated sludge (AS) has been widely adopted by various industries [25][26][27].…”

Nanotechnology activities: environmental protection regulatory issues data

“…This finding has already been confirmed by the scientific literature, which shows that the application of various types of engineered nanomaterials has gained attention in recent years [ 29 , 30 , 31 ]. In this sense, several metallic and non-metallic compounds were synthesized and used in order to remove various environmental contaminants [ 32 , 33 , 34 ].…”

Delphi-AHP and Weighted Index Overlay-GIS Approaches for Industrial Site Selection. Case Study: Large Extractive Industrial Units in Iran

“…It is evident that after decision-making process based on the results raised from this study, it would be necessary to carry out specific local environmental studies such as environmental impact assessment to establish an ecofriendly industry, which can ensure the economic benefits in a long-time life cycle [31], [32]. Sustainable designs are also required to control the pollutants released to the environment to ensure that the industry is developed completely eco-friendly [33], [34].…”
