“…The above mentioned specific particle size was found to be around 70 microns for water, but its value slightly went up when viscous glucose solutions were employed. The particle size distribution for the activated sludge flocs in the present study was not measured but most previous reports point to an average particle size lower or much lower than 70 microns [22,50,51]. In the present study, according to Eq.…”

“…In wastewater treatment systems, hydraulic retention time (HRT) is an important design parameter which has a significant influence on system design, operational /investment cost, process efficiency and energy requirements (Kuscu and Sponza, 2009;Shariati et al, 2011;Zhang et al, 2012). In general, lower HRTs are desirable from economic viewpoints because higher HRTs will lead to greater investment costs.…”

Bioelectrochemical systems could have potential for bioremediation of contaminants either in situ or ex situ. The treatment of a mixture of phenanthrene and benzene using two different tubular microbial fuel cells (MFCs) designed for either in situ and ex situ applications in aqueous systems was investigated over long operational periods (up to 155 days). For in situ deployments, simultaneous removal of the petroleum hydrocarbons (>90% in term of degradation efficiency) and bromate, used as catholyte, (up to 79 %) with concomitant biogenic electricity generation (peak power density up to 6.75 mWm -2 ) were obtained at a hydraulic retention time (HRT) of 10 days. The tubular MFC could be operated successfully at copiotrophic (100 ppm phenanthrene, 2000 ppm benzene at HRT 30 days) and oligotrophic (phenanthrene and benzene, 50 ppb each, HRT 10 days) substrate conditions suggesting its effectiveness and robustness at extreme substrate concentrations in anoxic environments. In the MFC designed for ex situ deployments, optimum MFC performance was obtained at HRT of 30 h giving COD removal and maximum power output of approximately 77% and 6.75 mWm -2 respectively. The MFC exhibited the ability to resist organic shock loadings and could maintain stable MFC performance. Results of this study suggest the potential use of MFC technology for possible in situ/ex situ hydrocarbon-contaminated groundwater treatment or refinery effluents clean-up, even at extreme contaminant level conditions.

“…In addition, new technologies have also been reported such as Microwave-assisted catalytic wet air oxidation (Sun Y. et al, 2008) and Membranes (Shariati et al, 2011;Yuliwati E. et al, 2011). Diyauddeen et al (2011) reviewed treatment technologies for petroleum refinery effluents and showed that the petroleum refinery effluents treatment consisted of two main steps, which are pre-treatment and advanced treatment.…”

The objective of this study is to summarize studies and investigations about advanced oxidation processes (AOPs) used for the treatment of petroleum wastewater, which mainly contained oil, organic matter and other compounds. The big difference was shown in the specification of wastewater among the investigated studies and a wide variety of pollutants at varying concentrations. The most compounds in petroleum wastewater were the mixture of hydrocarbons and inorganic compounds. Advanced oxidation processes (AOPs) have a capability of rapid degradation of recalcitrant pollutants in the aquatic environment. However, the literature regarding petroleum wastewater treatment is very little and advanced oxidation processes (AOPs) are still not being used on an industrial scale in oil refineries. Most studies were focused on the degradation of some pollutants found in the petroleum wastewater such as sulphides, ammonia, phenols and organic materials. This review focused on works that investigated advanced oxidation processes (AOPs) by monitoring general petroleum wastewater parameters such as TOC, COD, BOD, oil, and phenols. It presented an overview of photocatalytic degradation of pollutants in petroleum wastewater and highlighted the basics of these processes including the optimum parameters.
