Answer 1

Think about a tub of water, put some die in a corner, and a pump with a filter in the other corner.

The turbulence will slowly mix the whole tub, and yes you can only suck and clean what goes into the pump it will still slowly remove it from the tub as a whole. The parts per million count over the whole tub will decrease and the rate of removal will decrease over time.

Even dragging your finger around (person walking through the room) will agitate the fluid and make sure the pump inlet always has some adulteration to be cleaned.
