  • Refinery Wastewater

    A refinery was storing wastewater in several tanks and needed to meet the city discharge limits before they were allowed to dispose of the water. The problem was with soluble sulfides (1,000 ppm in the water) as the discharge was 0.5 ppm. Integrated Engineers was contacted to see if they could create a treatment process to reduce the sulfides to discharge limits. Several large water treatment ...

  • Treatment Of Edible Oil Refinery Wastewater

    AbstractIndustry manufacturing refined edible oil with a capacity of 18000 tones/annum generated wastewaters and solid wastes (viz. spent earth, chemical and biological sludges). The wastewater streams were mainly from vat house after soap splitting, floor washing, cooling tower, boiler and filter press. The chemical composition of the wastewater from cooling tower and boiler sections and solid ...


  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • Comparative evaluation of As, Se and V removal technologies for the treatment of oil refinery wastewater

    In this study, a broad range of readily deployable metal removal technologies were tested on a US refinery's wastewater to determine vanadium, arsenic and selenium removal performance. The bench-scale treatability studies were designed and performed so that test conditions could be as uniform as possible given the different mechanisms of action and engineering applications of each technology. The ...

  • New trends in oil refinery wastewater reclamation

    Six of the ten largest companies in the world are Oil Companies. This fact would support the argument that there may be no industry more competitive than the Oil Industry.  Within the Oil Companies, the toughest challenges lie within the Refining Divisions. Extreme pressures exist to expand capacities, to produce products which generate market advantages, to improve upon environmental ...

  • Pre–treatment of refinery spent caustic by Fenton's reaction

    Experimental results for applying Fenton oxidation as a pre–treatment method for spent caustic are presented. A combination of dilution and Fenton's reaction is proposed as a method for reduction of total COD and total phenols in spent caustics. This approach was used to obtain a decrease in total phenols from 5,200 mg/L to less than 130 mg/L. The greatest removal occurred within a pH range of ...

    Untitled Document The use of microorganisms to remove contaminants from wastewater is effective and widespread. To choose the right system from the many options offered, ...


  • Treatment of petroleum refinery wastewater by distillation-assisted catalytic oxidation under low temperature and low pressure

    A distillation-assisted catalytic oxidation (DACO) process under low temperature (100 °C) and atmospheric pressure was investigated to treat heavily contaminated wastewater from oil refining industry. The DACO experiments were carried out in a distillation batch reactor, using CuO/γ-A12O3 as catalyst. The experimental temperature was kept at 100 °C and H2O2 oxidant was supplied into the reactive ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • Treatment of petroleum refinery wastewater using a sequential anaerobic–aerobic moving-bed biofilm reactor system based on suspended ceramsite

    In this study, a novel suspended ceramsite was prepared, which has high strength, optimum density (close to water), and high porosity. The ceramsite was used to feed a moving-bed biofilm reactor (MBBR) system with an anaerobic–aerobic (A/O) arrangement to treat petroleum refinery wastewater for simultaneous removal of chemical oxygen demand (COD) and ammonium. The hydraulic retention time ...

  • Evaluating photo-degradation of COD and TOC in petroleum refinery wastewater by using TiO2/ZnO photo-catalyst

    The aim of this study is to investigate the performance of combined solar photo-catalyst of titanium oxide/zinc oxide (TiO2/ZnO) with aeration processes to treat petroleum wastewater. Central composite design with response surface methodology was used to evaluate the relationships between operating variables for TiO2 dosage, ZnO dosage, air flow, pH, and reaction time to identify the ...

  • Regenerative thermal oxidizer - Wastewater treatment facility

    Epcon has extensive experience in designing and building Air Pollution Control Systems for the Wastewater Treatment Industry. The Problem The water treatment plant could no longer have open storage tanks to store industrial wastewater from the refineries in the area. They were emitting VOC's from their open storage tanks and were required to reduce their VOC emissions by ...

  • Biodegradation of phenol in refinery wastewater by pure cultures of Pseudomonas aeruginosa NCIB 950 and Pseudomonas fluorescence NCIB 3756

    The potential of microorganisms to catabolise and metabolise xenobiotic compounds has been recognised as a potentially effective means of toxic and hazardous wastes disposal. Phenol and its derivatives have long been recognised as some of the most persistent chemicals in petroleum refinery wastewaters, with high toxicity even at low concentrations. Biodegradation of these compounds has been ...

  • Starndard Batch Treatment of Free and Soluble Oil Wastewater

    Small and Medium metal-based manufacturing plants produce between 1,000 and 30,000 gallons per week of oil-laden wastewater. Typically, the oil load is less then 2,000mg/l as soluble oil. Free (globular) oil is typically removed by DAF, oil-water separator, or coalescer with the remaining soluble oil needing to be reduced to less then 100mg/l in order to discharge directly to the local sewerage ...


  • Calibration and verification of models of organic carbon removal kinetics in Aerated Submerged Fixed-Bed Biofilm Reactors (ASFBBR): a case study of wastewater from an oil-refinery

    The article presents a case-study on the calibration and verification of mathematical models of organic carbon removal kinetics in biofilm. The chosen Harremöes and Wanner & Reichert models were calibrated with a set of model parameters obtained both during dedicated studies conducted at pilot- and lab-scales for petrochemical wastewater conditions and from the literature. Next, the models were ...
