Treatment of petroleum refinery wastewater by physicochemical methods

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...

Treatment 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...

Bioremediation of Petroleum Refinery Wastewater Effluent via Augmented Native Microbes

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...

Refinery wastewater treatment and reuse

0 A tremendous amount of material has been written about wastewater treatment and reuse in recent years. This is partly due to the constantly changing technology in the field. Controversy surrounding the promulgation of regulations by the Environmental Protection Agency (EPA), and subsequent revisions, have added to the confusion. The purpose of this article is to attempt to tie this mass of in...
