Illustrate Water Treatment System

Illustration similar to this link [login to view URL] , i need to show illustrate 3 parts like this, 1st part is a hydrospin ( its about 150mm wide and 1m long cylinder with holes on top) will send images, the water comes in at top and is forced to the bottom by little channels creating a vortex ( whirlpool ) in the chamber, the vortex forces the water downwards and the oil upwards. 2nd part is a tank that shows it fills up with water and oil, the oil floating on water overflows into oil tank. 3rd part is a filter showing dirty water incoming, filthy particles getting stuck in filter and clean water passing through the rest of the illustration and animation I will do myself, just need help on these 3 parts, can be done in Realflow/Blender or even flash ( to look like the link above ) Job is urgent
