Phenolic wastewater degradation by AnMBR
Last updated: 26 June 2017 at 11:53
Industrial and chemical wastewater are produced every day in huge amounts. These waster waters posse a big challenge to the conventional waste water treatments systems due to their composition, which have a high concentration of toxic and recalcitrant compounds. One example of these type of effluents are the one that came of the coal gasification.
Phenol and phenolic compounds can be considered as the main pollutants of the coal gasification wastewater. Although phenol can be biodegraded, high concentrations can disrupt the biomass of the reactors, promoting the death and washout of the main microbial population in charge of the bioconversion of the pollutants.
The anaerobic membrane bioreactor (AnMBR) is a technology that rises for tackling the above mentioned problems, due to the membrane that is coupled to the system, the AnMBR ensure a complete biomass retention providing the necessary characteristics for development of the necessary microorganisms.
The aim of this research is to analyze the biological degradation process of phenol, p-cresol, and resorcinol in anaerobic membrane bioreactors (AnMBR) under mesophilic conditions and the degradation of phenol under thermophilic conditions.
This PhD project is part of the BioXtreme project, which its goal is to show the potential of AnMBR technology for the treatment of chemical wastewaters under extreme conditions. So, in this PhD research the extreme conditions are: 1) high toxicity, be given by the phenolic compounds and its mixture; 2) high temperature, given by the thermophilic (48-55 °C) operation.
Especial attention will be paid to unravel the biochemical, microbiological and physicochemical processes related to the degradation of the toxic compounds under the mesophilic and the thermophilic conditions, as well as the study of the membrane performance (filterability, clogging potential, etc.).
