The main purpose of ultrafiltration is not for exchange of oxygen or nutrients or even the removal of waste products. These are of negligable importance. The primary purpose of ultrafiltration is really for the maintainance of the plasma and intersitial fluid volumes.

For insoluble impurities a method is ultrafiltration.
To purify whatever your filtering to absolute extent, to rid it of everything until its absolutely clean.

Filtration is done by a filter paper, while ultrafiltration is done by a semipermeable membrane. Solute particles that are 1-200nm in diameter can pass through filter paper, but cannot penetrate the semipermeable membrane. Only particles with a diameter less than 1nm can pass through the semipermeable membrane.
