Biological Treatment Process

The treatment of petroleum refinery wastewater was studied using a bench scale ultraviolet/hydrogen peroxide (UV/H2O2) process. The highest treatment performance of the bench scale UV/H2O2 process to reduce the total organic carbon (TOC) from the petroleum refinery wastewater took place at a reaction time of 45 min and a pH of 5.0. A three factor analysis of va riance (ANOVA) analysis verified that the initial H2O2/TOC molar ratio did not have a significant effect on the bench scale UV/H2O2 process treatment performance. The effects of adding UV/H2O2 treated petroleum refinery wastewater to activated sludge microorganisms form the refinery WWTP biological treatment process was studied using respirometry. Overall, the UV/H2O2 treated refinery wastewater inhibited the refinery activated sludge microorganisms. This occurred when the raw refinery wastewater was treated with a UV/H2O2 process for 45 min. with an initial H2O2/TOC molar ratio of 1.7 mol H2O2/mol C, an initial H2O2 concentration of 202 mg H2O2/L and a pH of either 5 or 7.

Abstract Based on discussions in workshop sessions, several recurring themes became evident with respect to the optimization and control of petroleum refinery wastewater treatment systems to achieve effective removal of toxic contaminants. It was apparent that statistical process control (SPC) techniques are finding more widespread use and have been found to be effective. However, the implementation of real-time process control strategies in petroleum refinery wastewater treatment systems is in its infancy. Considerable effort will need to be expended to demonstrate the practicality of on-line sensors, and the utility of automated process control in petroleum refinery wastewater treatment systems. This paper provides a summary of the discussions held at the workshop.

Abstract Several online analytical instruments are commercially available to allow continuous monitoring of petroleum industry wastewater treatment plants. Satisfactory usage of these instruments requires -special attention for sample preconditioning and sample characterization prior to selection. Specific examples of the available instruments are provided. Effective maintenance of instruments is emphasized.
