What Is Liquid Membrane And How Does It Work?

Liquid membrane technology is a relative innovation in water filtration. So what is this membrane, and how does it work?

What should I know about this?

Liquid membranes are thin, flexible membranes that are a barrier between two liquids. They contain tiny pores or holes, called micropores, that allow specific molecules to pass through while blocking larger ones.

There are several different types of liquid membrane technologies out there. The most common one is called a supported liquid membrane (SLM), where the membrane is made from plastic or another material and then coated with a thin film of liquid surfactant. This technology utilizes naturally occurring compounds in soil or water to create a unique pore structure within the membrane.

So how do these liquid membranes work? When a substance enters the liquid membrane, it can either be absorbed by the surfactant or pass through the micropores. If absorption occurs, then the entire molecule gets taken up into the liquid layer. The opposite happens if a substance goes through the pores – only smaller molecules get carried away.
