This study investigated the effects of residual ozone on the performance of microorganisms treating petrochemical wastewater using batch experiments with low and high ozone dosages (5.0 mg/L and 50.0 mg/L, respectively). The results indicated that the low residual ozone concentration significantly increased COD removal by 24.21% in the biological process compared to control group with no ozone residual, while the high residual ozone concentration showed the opposite effect. In the reactor with…

Treatment of secondary effluent from a petrochemical wastewater treatment plant by ozonation‐biological aerated filter
BACKGROUD Secondary effluent collected from a petrochemical wastewater treatment plant was treated by ozone–biological aerated filter (O3-BAF) to investigate and evaluate the performance, organics
Removal of organics and degradation products from industrial wastewater by a membrane bioreactor integrated with ozone or UV/H₂O₂ treatment.
The treatment of a pharmaceutical wastewater resulting from the production of an antibacterial drug (nalidixic acid) was investigated employing a membrane bioreactor (MBR) integrated with either
Treatment of petrochemical secondary effluent by an up-flow biological aerated filter (BAF).
The biomass and microbial activity of the microorganisms on the filter media were in general reduced with increasing filter height, which is consistent with the removal profile of the contaminants.
Advanced Treatment of Caprolactam Production Wastewater by Ozone-Activated Sludge Process
Caprolactam production wastewater was treated by ozone-activated sludge process. When the ozone dosage is 60 mg/L and HRT=24 h,the COD and ρ(NH 3-N) of the effluent are 54.7 mg/L and 2.0 mg/ L
Biological treatment of actual petrochemical wastewater using anaerobic/anoxic/oxic process and the microbial diversity analysis
A novel process integrating anaerobic hydrolysis-acidification (HA) and anoxic/oxic (A/O) reactors was developed to treat the actual petrochemical wastewater, which was operated for more than 8
Investigation on evaluation criteria of backwashing effects for a pilot-scale BAF treating petrochemical wastewater
Concentrations of the benzene, toluene, ethylbenzene and (o-, m-, p-) xylenes and phenol in the backwashed sludge were analyzed, showing that the backwashing was essential to remove some aromatic compounds adsorbed in the microorganisms.
