a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...

A simple two-stage chemical solution process is reported, to deposit a superhydrophobic film on copper foams with view be employed in oil absorption or filtration procedures. The first stage includes the growth of silver layer increase micro roughness and second one evolves modification using stearic acid. whole time-saving, cost effective versatile. UV-Vis spectroscopy was determine optimum de...

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...

Oily wastewater and oil spills pose a threat to the environment human health, absorbing these harmful organics through porous aerogel materials is an efficient method for oil/water separation.

On the basis of key ways of oily waste treatment in Russia which has been described in the article and on the example of oil-contaminated soil (OCS) treatment there can be considered two most widespread technologies: bioremediation and thermal recovery. We developed the process flow sheet of the equipment (UT-2S) for industrial oily wastes treatment on the basis of high temperature air tight de...
