چکیده
Combining ultrasonic irradiation and the Fenton process as a sono-Fenton process, chemical oxygen demand (COD) in refinery wastewater was successfully eliminated using response surface methodology (RSM) with central composite design (CCD). The impact of two main influential operational parameters (iron dosage reaction time) on COD removal from generated by an Iraqi petroleum facility explored. Removal 85.81% attained under optimal conditions 21 minutes 0.289 mM concentration. Additionally, results revealed that concentration has highest effect elimination, followed time. high R2 value (96.40%) validated strong fit model equation successful adopting RSM treatment wastewaters refineries. Furthermore, comparison among sono-Fenton, addition externally, classical sonolysis processes showed combined is better than individual external .

Anaerobic Treatment of Petroleum Refinery Wastewater
Anaerobic treatment has many advantages over other biological method particularly when used to treat complex wastewater such as petroleum refinery wastewater. In this study two Up-flow Anaerobic Sludge Blanket (UASB) reactors were operated in parallel to treat six volumetric organic loads (0.58, 1.21, 0.89, 2.34, 1.47 and 4.14 kg COD/m·d) to evaluate the chemical oxygen demand (COD) removal eff...

Petroleum refineries discharged large amount of wastewater -during the refining processthat contains hazardous constituents that is hard to degrade. Anaerobic treatment process is well known as an efficient method to degrade high strength wastewaters. Up-flow Anaerobic Sludge Blanker (UASB) is a common process used for various wastewater treatments. Two UASB reactors were set up and operated in...
متن کاملEfficiency of Fenton Process in Olive Oil Mill Wastewater Treatment
Background and purpose: Wastewater olive processing industries have significant amounts of organic compounds resistant to biodegradation which are hazardous if not treated and discharged to the environment. Advanced oxidation processes such as Fenton process have been considered to increase and improve the biological degradability of this type of wastewater. Current study aimed at investigating...

Introduction: Most commercial surfactants used for cleaning (as detergents (are part of xezenbiotic compounds. These compounds and products due to its toxic effects on aquatic organisms may interfere with hormonal system and consequently change the echo system. Since the biodegradation of those compounds are weak, ordinary methods are unable to break down conventional purification. Therefore, t...
متن کاملEfficient Rapid Deodorization of Mercaptan-Contaminated Soil by Sono-Fenton Process: Response Surface Modeling and Optimization
The entry of mercaptans into the environment as an odor pollutant has always been considered as one of the environmental concerns. In this research, a sonochemical oxidation (sono-Fenton) method was used for rapid deodorizing of tert-butyl mercaptan (TBM) contaminated soil. The design of the experiments was conducted by CCD method and the effect of four different factors was investigated on the...
