I tried to "unscrew" this one, but it seems not screwed at all; it just spins. Is there any way to remove this? As it is a separate part, there must be a way to remove it. Please help.

A bit late, but for anyone still wondering I had this problem today. I took two forks and put one prong on each into those little notches and turned counter clockwise until I felt it becoming loose. At that point, I just had to unscrew it a bit more and it came off.
Does that whole round bulb part unscrew? It kinda looks like it might. Might spray some lime away on the whole works to get a better idea how it's put together. It looks like maybe the white part should unscrew. Like the white was the aerator but the screens have been pushed out.
Found a similar design at the Delta website. The round knurled piece should unscrew. The male threaded section should also unscrew. Apparently some have a hex shape to facilitate installation. Some have an internal female hex shape that is removed by an allen wrench. This allows the retaining plate to be removed. If there is enough room between the backsplash and the spout you could try holding the piece under the sink with a pipe-wrench, vise grips or large pliers and have someone spin the faucet.
