“…Furthermore, biofilm formation would be limited as a result of the high levels of aeration applied in aeration cell and resulting shear . In addition, any further benefit of PAC in relation to biofilm formation would be limited as a result of the high SRT of 38 days present under normal operational conditions and a long‐term adaptation period required for biofilm formation which was not accounted for in this investigation . Longer‐term investigations are required to investigate whether biofilm formation would result in biological degradation rather than adsorption alone.…”

“…The use of activated carbon (AC) has received considerable attention for a number of decades for the removal of pollutants found in both industrial and domestic wastewaters and may allow improved treatment efficiencies of coke‐making wastewater. Activated carbon can be applied as a pre‐treatment method, dosed directly into the treatment process or applied as a post‐treatment method .…”

“…Due to its larger pore size GAC is more suitable for heavy molecular weight pollutants . When added into the ASP, it acts as an absorbent while also providing a surface for microorganisms to grow in a biofilm . This allows pollutants to be absorbed and then diffused out gradually, allowing increased contact times between the microorganisms and pollutant, which enhances the removal of less easily degradable compounds which may require a higher residence time …”

BACKGROUND: Powdered activated carbon (PAC) was investigated for its ability to remove six polycyclic aromatic hydrocarbons ( 6PAHs) (fluoranthene, benzo[b + J]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene, benzo[g,h,i]perylene), trace metals and colour from coke-making wastewater when dosed to a pilot-plant activated sludge process (ASP). The ASP had a volume of 0.68 m 3 and was operated to simulate the full-scale ASP treating coke wastewater from a steel works. Operational conditions included a flow rate of 0.78 m 3 day −1 , a hydraulic retention time of 21 h, a sludge retention time of 38 days and a temperature of 27 ∘ C. The ASP was operated for a control period before PAC was dosed directly into the aeration cell at a dose of 400 mg L −1 .RESULTS: Powdered activated carbon addition resulted in a 20% increase in removal efficiency of the 6PAHs. Removal efficiency of trace metals was variable, but increased for nickel, chromium and cadmium by 22.6%, 20.5% and 12.4%, respectively. Improvement in colour removal efficiency was marginal at 5%. CONCLUSION: PAC addition allowed the improvement of treatment efficiencies in the ASP process at relatively low capital and operational costs, which may assist in reaching tighter effluent emission limits set for the industry.

“…The BAC systems were discovered and developed in drinking water treatment plants, and nowadays are in full scale operation in a large number of plants in Europe, the United States and Japan . Previous literature shows that BAC reactors could be used to remove acid dyes, phenol and 2,4‐dichlorophenol,, refractory landfill leachate, PAHs, and petrochemical wastewater . The current research situation is that BAC has a high degradation ability for toxic and refractory organic pollutants.…”

BACKGROUND: The wastewater originating from the production of acrylonitrile-butadiene-styrene (ABS) resin is a toxic and refractory industrial wastewater. The purpose of this work is to investigate the characteristics of adsorption and biodegradation of biological activated carbon (BAC) for ABS resin wastewater. RESULTS: More than 80% of chemical oxygen demand (COD), total organic carbon (TOC) and organic nitrogen (Org-N) was removed after the 100th run in BAC with the help of bioregeneration, and the treatment efficiency of BAC was higher than that of adsorption and biodegradation alone. The initial Org-N was mainly transformed into NH 4 + -N, and the transform efficiency reached 65% after the 100th run. After bioregeneration, the COD and TOC removal efficiencies of BAC reactor reached 88.97% and 86.26%, respectively. The BAC had different bioregeneration efficiencies of 94.41, 64.82, 61.05 and 40.04% for 3, 3-imminodipropiononitrile, 3, 3-oxydipropiononitrile, α, α-dimethyl-benzylalcohol and acetophenone, respectively, which mainly resulted from the different polarity of the compounds. CONCLUSION: BAC could protect microorganisms from shock loadings of toxic, refractory and complicated ABS resin wastewater. The mechanism of the organic pollutants removal by BAC consisted of three phases including adsorption, bioregeneration and stability.

A laboratory-scale powdered activated carbon treatment (PACT) process was conducted to treat the synthetic dye wastewater containing reactive brilliant blue KN-R (RBB). The pore structures of the PAC and molecular structure of the RBB were analysed. The influences of the biomass concentration and the PAC dosage on RBB removal were investigated in an activated sludge system. In addition, kinetic studies based on four fundamental models were investigated. Furthermore, theories about the microscopic dynamic interaction process of PACT were studied. A schematic process of the interaction between activated carbon and microorganisms in a PACT process was proposed. It was concluded that the enhanced treatment of dye wastewater by the PAC in activated sludge process was due to the immobilized microorganisms on the PAC and the bio-regeneration process.
