Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

Gas flotation for oily wastewater treatment is based on the attachment of gas bubbles to oil droplets produce lighter aggregates that rise surface. It a feasible, promising, and effective method due its high separation efficiency with no secondary contamination, cost-effectiveness, simple operation. This review focuses separating from emulsions by using microbubbles (MBs) nanobubbles (NBs), whi...

This study was undertaken to evaluate a novel aerobic wastewater treatment model for the remediation of refinery effluents and to assess the removal efficiency of Bulkholderia cepacia strain AJI and Corynebacterium kutscheri strain AJ2 to clean oil waste from petrochemical company. Wastewater quality parameters including pH, BOD5, COD, TDS, OIL & GREASE, PHENOL concentration, TPH and THC were m...

Produced water separated from oil is usually returned to the environment and could permeate through the water table. If such water is contaminated with radioactive substances, it could create a definite threat to the water supply, especially in arid regions where ground water and overhead streams are sources of potable water. Low-level radioactive contamination of oily sludge is equally hazardo...

Industrial developments in the oil and gas, petrochemical, pharmaceutical food sector have contributed to large production of oily wastewater worldwide. Oily pollution affects drinking water groundwater resources, endangers aquatic life human health, causes atmospheric pollution, crop production. Several traditional conventional methods were widely reported, advantages limitations discussed. Ho...
