Abstract (en)
[origin: DE4406239C1] A process and assembly separates solid and lipid materials from a fluid by means of reduced pressure flotation within a tank (14) incorporating a fluid inlet (15) and an inlet (16) for a mixt. of liq. and gas. The novelty is that the inlet (16) for the mixt. of liq. and gas incorporates a pressure-relieving element (19) which lowers the pressure within the tank (14) and arranged centrally beneath the fluid inlet (15).
