The discharge of water from oil fields is become one the most significant environmental concerns associated with sector. This study features a low-density polysulfide polymer prepared by Sulfur and used sunflower oils react directly. Because both sulfur cooking are hydrophobic, can easily extract hydrocarbons like crude diesel fuel saltwater. petroleum industry by-product, leftover may be utili...

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...

Abstract It is challenging to purify oily wastewater, which affects water-energy-food production. One promising method membrane-based separation. This paper reviews the current research trend of applying cellulose as a membrane material that mimics one three typical biostructures: superhydrophobic, underwater superoleophobic, and Janus surfaces. Nature has provided efficient effective structure...

BACKGROUND, AIM, AND SCOPE Polycyclic aromatic hydrocarbons (PAHs) are often found in oily wastewaters. Their presence is usually the result of human activities and has a negative effect on the environment. One important step in addressing this problem is to evaluate the effectiveness of PAH removal by biological processes since these are the most cost-effective treatments known today. Many tec...

Abstract Oily wastewater consists of fats, oils and greases together with a broad spectrum dissolved organic and/or inorganic substances in suspension. It is regarded as one the most hazardous wastewaters, causing serious environmental health threats to ecosystems, flora fauna. The global increase discharge oily coupled stringent regulations for effluent incessant drive re-use treated necessita...

Nowadays, oily wastewater is increasing along with the growth of various industries. So, wastewater treatment is necessary in order to protect the environment. In this study, a mullite ceramic membrane was prepared. Then, oily wastewater treatment with 200 mg L-1 concentration was investigated by the response surface methodology based on Box-Behnken design (BBD) using Design-Expert 7...

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...
