RISBiodegradation of Highly Concentrated Phenol and Ammonia in the Presence of Oxyanions in Sequential A<sup>2</sup>/O MBBR System
Publisher: ASCE
Abstract: In this study, a sequential fed-batch anaerobic–anoxic–aerobic (A2/O) moving bed biofilm reactor (MBBR) (A2/O MBBR) system will be employed for the simultaneous treatment of highly concentrated phenol, ammonia (NH4), and ...
Biodegradation of Phenol and Ammonia from Refinery Wastewater in Hybrid MBBR System by Native Mixed Bacterial Culture
Publisher: American Society of Civil Engineers
Abstract: A novel hybrid fed-batch moving-bed bioreactor (MBBR) system was developed for the treatment of refinery wastewater containing a wide range of phenol (250–1,000 mg/L) and ammonia-nitrogen (50 mg/L) using an indigenous ...
Biodegradation of Heterogeneous Pollutants in Hybrid MBBR System: Resilience Assessment under Different Shock Stress Conditions
Publisher: American Society of Civil Engineers
Abstract: The sudden increase in phenol concentrations is frequently observed in coke-oven, petrochemical, and petroleum refinery waste streams due to changes in process parameters, posing challenges for the biological treatment ...
Removal of Textile Dyes from Aqueous Solutions by Dolochar: Equilibrium, Kinetic, and Thermodynamic Studies
Publisher: ASCE
Abstract: The current study explicates the feasibility of using dolochar, a solid waste generated from the sponge iron industry, for removal of color from synthetic textile dye solution containing equal amounts of the dyes Reactive ...
