The performance of an aerobic membrane-coupled bioreactor (MBR) operating at mesophilicthermophilic transitional temperatures (40 ̊C) treating oily rendering wastewater has been evaluated in terms of COD, BOD5, oil and grease, solids and ammonia removal at 5 and 10-day HRT. The COD removal efficiency increased from 78% to 96%, BOD5 removal from 87 to 99% and oil and grease removal from 92 to 95%...

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 reduction. In this st...

In this study electrocoagulation (EC) process with sacrificial aluminum anode was used to separate crude oil from synthetic oily wastewater emulsion. A preliminary experimental study was performed to evaluate the most accurate operating parameters, which are then used for the determination of crude oil removal efficiency. The experimental results indicated that electrocoagulation was very e...

Wastewater treatment of machine-building enterprises contaminated with oils, petroleum products and mechanical impurities is an urgent task. A promising direction in the field such wastewater use pressure hydrocyclones hydrocyclone installations. The article presents results research on oil-containing hydrocyclones, conducted experimental installation, which includes under test, a sedative tank...
