RISBiodegradation 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 ...
Fabrication of Novel Ceramic Membrane Using Coal Fly Ash Blended with Fuller’s Clay for Separation of Technical Lignin
Publisher: American Society of Civil Engineers
Abstract: In this study, waste coal fly ash was blended with fuller’s clay to fabricate a novel ceramic membrane for the efficient separation of technical lignin from aqueous solutions. A circular ceramic membrane was prepared using ...
Biodegradation 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 ...
