Hi Michael, I am guesing that you are talking about the air bubbles in the water. Here’s what you could do:
Use a Bezier Circle as a Curve Guide for the Particles and make two particle Systems (that are the same apart from the time offset!)
Some notes:
Make sure the Emitter is not in the Camera view, because you might get cut off particles.
I tried this in 3.1, but couldn’t get the two Particle Systems to be the same, so I rendered 100 Frames and then added the first 50 with the second 50 together like this:

but of course using 2.93 is easier.
You can of course straighten the part of the Curve that is in the Camera view.
I hope this is helpful.
