Oily wastewater is generated from various sources within the petrochemical industry, including extraction, refining and processing, storage, transportation. Over years, large volumes of oily this industry have made their way into environment, negatively affecting human health, economy. The raw waters can differ significantly complex features, making them difficult to treat. Membrane bioreactors...

During the last two decades, and particularly during the last few years, the environmental sector has shown a largely growing interest in the treatment of different types of water and wastewater by electrocoagulation (EC). The aim of this work was to review studies, conducted mainly during 2008-2011, on the wide and versatile range of feasible EC applications employed in the purification of dif...

Oily wastewater has been recognized as a threat to the environment due its hazardous nature and it can negatively affect ecosystem, threaten wildlife human health. Physical, chemical, biological technologies demonstrated mixed performance in oily treatment, and, therefore, proper treatment technology for needs be addressed. Membrane filtration using hollow fiber (HF) membrane is promising alter...

Pollution associated with crude oil (CO) extraction degrades the quality of waters, threatens drinking water sources and may ham air quality. The systems biology approach aims at learning the kinetics of substrate utilization and bacterial growth for a biological process for which very limited knowledge is available. This study uses the Pseudomonas aeruginosa to degrade CO and determines the ki...

Synthetic oily wastewaters were prepared from metal working fluids (MWF). Electrocoagulation experiments were performed under constant voltage application. The current, conductivity, pH, dissolved oxygen concentration and temperature were recorded on line at every 5 seconds during the experiments. Effects of applied voltage differences, electrode materials and distance between electrodes on rem...

High-throughput microbial electrolysis cells (MECs) were used to perform treatability studies on many different refinery wastewater samples all having appreciably different characteristics, which resulted in large differences in current generation. A de-oiled refinery wastewater sample from one site (DOW1) produced the best results, with 2.1±0.2 A/m(2) (maximum current density), 79% chemical ox...
