Abstract Electrocoagulation technique using aluminum electrodes in a batch bi-polar system was investigated to determine the efficiency of removing oil from oily wastewater. The Box–Behnken design utilized optimize conditions and effects four independent factors, including volume ( X 1 ), temperature 2 initial pH 3 treatment time 4 ),—were examined investigate turbidity recovery conductivity ch...

The increasing amount of oily wastewater discharges caused major challenges for current environmental issues, such as oil-water purification and separation [1-6] . Thus, the development new functional materials efficient treatment is imperative [7-11] This paper reviewed recently developed technologies, which were based on novel nanomaterials, presented representative works in detail. Finally, ...
