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...
متن کاملTreatment of Petroleum Refinery Wastewater by using UASB Reactors
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 کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

In Nigeria, like other developing countries, industries discharge their wastewater without effective treatment due to the high cost of existing treatment technologies. Wastewater containing petroleum hydrocarbon is highly toxic and pose a great danger to the nearby communities. Therefore, there is a need for a more robust and cost effective treatment technology. In this research, a study was ca...
متن کاملInhibition of aflatoxin biosynthesis by phenolic compounds.
The phenolic compounds acetosyringone, syringaldehyde and sinapinic acid inhibited the biosynthesis of aflatoxin B1 (AFB1) by A. flavus. Acetosyringone was the most active among the three compounds, inhibiting aflatoxin level by 82% at 2 m moll-1. The synthesis and accumulation of norsolorinic acid, an aflatoxin biosynthetic intermediate, was also inhibited. These results suggest that at least ...
