Oil and water are difficult to separate without leaving some impurities – Abaca Press/Alamy

Mixing oil and water is a problem, but scientists have found a better way to separate them. By using special membranes in thin channels, they can recover pure oil and water. This is important for cleaning up industrial waste more efficiently.

There are different methods to separate oil and water, like using chemicals or membranes. The new method uses two layers of membranes – one for oil and one for water – to get rid of impurities.

In experiments, the scientists found that narrowing the channel width led to better oil and water recovery. By improving this process, they can clean the mixture more effectively.

The team believes that this new method can be scaled up for use in industries. It is a simple and efficient way to separate oil and water, making it easier to deal with waste.
