  • How is wastewater treated in petroleum refining?
  • Petroleum refining enterprises are equipped with wastewater treatment plants to collect and treat the PRW streams. The overall wastewater treatment process can be divided into pretreatment, primary, secondary, and tertiary (Fig. 2).
  • Is a combined process effective for treating industrial petroleum wastewater?
  • The VFA concentration further fell to 0.13 ± 0.6 mg L −1 after treatment in the HA unit (S3), and was completely eliminated following treatment in the first A/O unit (S4). This result shows that the combined process examined in this research is effective for treating the industrial petroleum wastewater.
  • What is the treatment of petroleum and petrochemical wastewater?
  • The treatment of petroleum and petrochemical wastewater is widely studies area of research. These streams are difficult to treat due to large concentrations of oil. The composition of effluent in refinery wastewater depends on the crude quality. It varies with the operating conditions (Benyahia et al., 2006).
  • What are the three types of petroleum wastewater treatment?
  • The petroleum wastewater treatments are classified into three types; physical, chemical and biological. However, the treatment required a typical application of the integrated system due to the complexity of characteristics of petroleum wastewater. Thus, the conventional treatment methods need multistage process treatment.
