The effects of industrial effluent discharge on the water quality River Rido in Kaduna South, State, were examined. These include Northern Noodles point, Refinery and points downstream Rido. An interval 100m between sampling was established to achieve an even representation points. physico-chemical parameters investigated pH, free dissolved carbon dioxide, alkalinity, hardness, sodium, electric...

An Arthrobacter sp. strain, F101, able to use fluorene as the sole source of carbon and energy, was isolated from sludge from an oil refinery wastewater treatment plant. During growth in the presence of fluorene, four major metabolites were detected and isolated by thin-layer chromatography and high-performance liquid chromatography. 9-Fluorenol, 9H-fluoren-9-one, and 3,4-dihydrocoumarin were i...

In the present study the modified Ludzack-Ettinger predenitrification process was employed for the biological treatment of oil refinery wastewater. For this purpose an anoxic tank coupled to an oxic MBR operated at SRT and HRT of 60 days and 24hr , respectively was used. The findings of the present study showed that using a recylcle ratio (R) equal to both 2 and 4, COD and phenol removal effici...

Oxygen is one of the most important products in chemical industries. This chemical element is used in various processes such as: refinery industries, manufacturing metal and other industrial operations. For instance, oxygen with high purity is utilized in different chemical processes like: steel construction, paper industries, wastewater treatment and glass production. In 1907, oxygen was produ...

Reasons for Blending Crude Oils at a Refinery Oil refineries, and especially their on-process units that process the primary crude feed stocks, are not uniform in either design or operation. The refinery process units and the combination of units built and in service at a given refinery location are part of a plan to accommodate a certain slate of crudes based on their properties. These decisio...
