Continuous Bioregeneration of Granular Activated Carbon During the Anaerobic Degradation of Catechol

Removal of catechol from aqueous solution by advanced photo-oxidation process

“…However, comparatively little attention has been paid on removal of catechol [10,11] though it is reported to one of the important substituted phenolic compounds present in different industrial effluent. The objective of the work was preliminary to characterize the oxidative degradation of dilute aqueous solution of catechol by using hydrogen peroxide in presence of UV light.…”

Treatment of chemical-pharmaceutical wastewater in packed bed anaerobic reactors

“…Many materials can be used as attachment media for the microbial population in the packed bed reactors and their characteristics are important for successful performance and operation. There are reports in the literature concerning the successful use of granular activated carbon (GAC) in fluidized bed anaerobic reactors to remove catechols (Suidan et al, 1980), polycyclic compounds (Wang et al, 1984) and phenols (Wang et al, 1986), in the treatment of wastes from the gasification of carbon (Suidan et al, 1983;Fox et al, 1988) and from leachates (Suidan et al, 1993;Kupferle et al, 1995). The presence of xenobiotic compounds in the chemical-pharmaceutical effluents justifies the use of GAC in the anaerobic packed bed reactors as well.…”

Effects of some alkyl phenols on methanogenic degradation of phenol

“…Wastewaters containing phenols have traditionally been treated by using physical, chemical, and aerobic biological processes. Recently, anaerobic biological processes have been used for the treatment of phenolic wastewaters (7,10,(13)(14)(15)(16)18). Some phenolic compounds, including phenol, m-cresol, and p-cresol, have been shown to be biodegradable to methane and carbon dioxide in batch anaerobic cultures (1-3, 6, 9, 19).…”
