“…Biological treatment is commonly used in refineries to treat PRWW, following separation and flotation processes (Pajoumshariati et al, 2017). Therefore, current research into the biodegradation of PRWW is focused on optimising the design and operating conditions of bioreactors.…”

“…A complication of biological treatment is the production of sludge, which is subject to regulation as a solid waste (Santo et al, 2013). Microbial populations require an adaptation period to adjust to their environment prior to degradation and can be quite sensitive to toxic loading conditions (Pajoumshariati et al, 2017). Despite this, PRWW is seen as a suitable substrate for biological treatment due to its high hydrocarbon content, which microorganisms can fully degrade under the right conditions (Mallick and Chakraborty, 2017).…”

“…Biological treatment systems require an inoculation period where the reactor is inoculated with bacteria-containing sludge and are often dosed with nutrients throughout operation to maintain microbial populations (Mallick and Chakraborty, 2017). One important parameter for biological treatment is the hydraulic retention time (HRT), which is a measure of wastewater treatment time (Santo et al, 2013 reactors and fluidised bed reactors (Pajoumshariati et al, 2017;Santo et al, 2013;Schneider et al, 2011). The results from several studies which employed one of these forms of biological treatment on PRWW are summarised in Table 3.…”

“…Although several refineries employ wastewater reuse processes where possible, such as the use of wastewaters from fluid catalytic cracking processes for desalting processes, complete reuse of wastewater is currently not a viable option (Burks and Wagner, 1983). The current treatment of petroleum refinery wastewater (PRWW) typically involves gravitational oil-water separation, air flotation for suspended matter removal, and activated sludge biological treatment (El-Naas et al, 2016;Li et al, 2015;Pajoumshariati et al, 2017;Wang et al, 2015). While biological treatment is typically sufficient in reducing the high concentrations of organics, the high chemical oxygen demand (COD) and high concentrations of sulphides and other contaminants present challenges for the viability of biological treatment alone (El-Naas et al, 2016;Mallick and Chakraborty, 2017).…”

The global economy's continued dependence on fossil fuels is associated with a multitude of environmental concerns, including the production of hazardous wastes in petroleum refineries. Large quantities of petroleum refinery wastewater (PRWW) are produced daily, requiring the development of appropriate treatment methods. Activated sludge biological treatment is commonly used to treat PRWW; however, this treatment method has a high sludge production, high operational time and may not be optimally suited for the variable loading conditions of refineries. Multi-criteria analysis (MCA) is a tool capable of evaluating different wastewater treatment technologies through the weighted consideration of multiple environmental and economic factors. The following methods of treating PRWW were reviewed and evaluated using a multi-criteria analysis: biodegradation, advanced oxidation processes, electrocoagulation and microbial fuel cell technology. The MCA considered removal efficiencies, sludge production, cost-benefit, process complexity and operational time of each method and was conducted under six different weighting scenarios. Advanced oxidation processes were preferred by this analysis under all six scenarios, with overall index scores (OIS) ranging from 7.84 to 8.51 out of a possible 10 points. Biodegradation of PRWW obtained was found to have the greatest overall removal efficiencies; however, the high operational time and sludge production of this method resulted in a maximum OIS of 7.59. Electrical methods, such as electrocoagulation and microbial fuel cell technology, required further improvements in removal efficiencies to be considered as a standalone treatment method. Further research into all methods, particularly microbial fuel cell technology, is recommended.

Refinery wastewater treatment was performed using a novel submerged tubular ceramic membrane bioreactor (STMBR) with the oleaginous hydrocarbonoclastic bacterium Rhodococcus opacus. A membrane‐based flux study with the STMBR was carried out to assess the performance of the tubular ceramic membrane. Continuous experiments with the STMBR achieved a maximum chemical oxygen demand (COD) removal of 84 %, with an average flux of 0.4 × 10−3 m3m−2s−1. To further enhance the COD removal efficiency, two STMBR were operated under the optimum conditions. Complete COD removal along with 2.98 g L−1 biomass growth was achieved during two‐stage STMBR operation. Furthermore, a toxicity assessment of the permeate water established its reuse potential.

Owing to the high demand of petroleum and petrochemical products, refineries, among the many industries that are set up worldwide, are of special importance. Wastewater generated from such industrial activities, however, contains toxic compounds that are of environmental concern. Due to the presence of highly recalcitrant organics present in refinery wastewater, treatment prior to its discharge into the environment and water bodies in order to meet certain acceptable discharge limits is imperative. Petroleum refineries unavoidably discharge a large volume of wastewater mainly with high chemical oxygen demand (COD). Low‐cost biological wastewater treatment methods are reported to show excellent COD removal efficiency from wastewater but have their own drawbacks. Hence, advanced integrated approaches are of new interest in this field. This review focuses on emerging technologies, in particular bioreactor configurations for petroleum wastewater treatment. It further discusses some future perspective in hybrid/integrated systems for treating PRWW.
