Researchers have found an effective method of water purification from oil Bashny.Net

The membrane, developed by engineers at mit, can separate the small flakes of butter and oil from water.

In addition to the use of this technology for oil spills in water bodies, it is useful for the routine operations of drilling when wells pumped a large amount of water. A new approach to the separation of water and oil presented by a group led by Kripa Varanasi. Scientists have proposed to use a thin membrane with different structures of pores.

Varanasi explains that the pores should be less than a drop to block them. But this leads to a significant flow resistance, limiting the throughput. So the team found a unique way: the large openings on one side give a small flow resistance, and nanosized pores in contact with the emulsion and separated components of the fluid.





This technology: the combination of a very thin layer of nanopores with wider anothertime, effectively limiting the passage of unwanted materials, while providing high throughput and is able to withstand high pressure. The membrane can be performed with different contrast properties to repel oil and to absorb water or Vice versa.
