TLDR
Treatment of simulated wastewater containing 40 mg/l of 4-chlorophenol (4-CP) was carried out in an upflow anaerobic sludge blanket (UASB) reactor under methanogenic condition and the ring cleavage test showed the ortho mode of ring cleaved 4-CP.About:

Journal ArticleDOI
Comparison of UASB and EGSB performance on the anaerobic biodegradation of 2,4-dichlorophenol.
TL;DR: Efficiency of dechlorination was improved in both reactors from around 30% to 80% by reducing to one-half the COD due to a decreasing of the 4-chlorophenol concentration accumulated in the effluents of both reactors.
Journal ArticleDOI
Dechlorination of 4-chlorophenol to phenol in bioelectrochemical systems.
TL;DR: This study explored the use of a BES to abiotically cathodic dechlorination of aromatic chlorides such as 4-chlorophenol, where the process was driven by microbial oxidation of glucose at the anode, and confirmed that the 4-CP reduction process was feasible in BES and the de chlorination efficiency could achieve 50.3% at the cathode with energy generation.
Journal ArticleDOI
Inhibition of methanogenesis by chlorophenols: a kinetic approach.
TL;DR: A general kinetic model has been applied to predict the inhibition of methanogenesis by chlorophenols, and it can be used for updating the IWA-ADM1 when treating inhibitory compounds.
Journal ArticleDOI
Enhanced reductive transformation of p-chloronitrobenzene in a novel bioelectrode-UASB coupled system.
TL;DR: Results showed that a stable COD removal efficiency over 99% and high p-ClNB transformation rate of 0.328 h(-1) were achieved in the bioelectrode-UASB coupled system, which demonstrated the catalytic reduction of p- ClNB by biocathode in the combined system.
Journal ArticleDOI
Development of an energy-saving anaerobic hybrid membrane bioreactors for 2-chlorophenol-contained wastewater treatment.
TL;DR: The effluent turbidity from the AnHMBR system was low during most of the operation period, and the chemical oxygen demand and 2-CP removal efficiencies averaged 82.3% and 92.6%, respectively.

Use of Fenton reagent to improve organic chemical biodegradability.
TL;DR: Fenton reagent has been used to test the degradation of different organic compounds in aqueous solution and eliminates the toxic substances and increases the biodegradability of the treated water (measured as the ratio BOD5/COD).

TL;DR: The toxicity of treated solutions was dependent on the addition mode of HRP and hydrogen peroxide, and solutions that were treated in the presence of chitosan exhibited lower toxicities than solutions treated in its absence if they were allowed to incubate for an extended period of time.
