Hello

Looking for some help to understand why this is happening, and is it possible solve this problem

I got a Separatory funnel with a long stem adapter attach to it. Inside the sep funnel i got 2 liquids, water and naphtha. The naphtha is running through the water with the help of the adapter.

But over time a huge emulsion appear (lots of bubbles). And i can see inside the sep funnel when the emulsion is thick enough of bubbles, some of the bubbles will begin to float and float to the top and out of the sep funnel. So after 20mins i can see that the water layer is reduce because of the bubbles. (Though that the water will always be at the bottom even if its was a bubble)

So why is this happening ?
Can this be caused by that the liquid is to cold?

Thanks
