Abstract

A method and apparatus for mixing fluids comprising aspirating at least one fluid by means of a suction means (B); transporting said fluid through said suction means (B) and a defoaming unit (C) communicating with said suction means (B); defoaming the aspirated fluid in the defoaming unit (B) by virtue of subjecting the fluid to a G-force other than the force of gravity in said defoaming unit to thereby provide a quick and effective elimination of substantially all foam which may be present in the fluid aspirated by the suction means; in situ measuring the flow of said defoamed fluid output from said defoaming unit (C); dosing an additive into the fluid at said output of said defoaming unit (C), from an additive container (27) via a connection conduit (29), in dependence of, preferably proportional to, the measured flow of said fluid; transporting the fluid and the additive through a mixing unit (F) communicating with said defoaming unit; mixing the aspirated fluid with the additive in the mixing unit by virtue of subjecting the fluid and the additive to a G-force other than the force of gravity in said mixing unit to thereby provide a quick and effective mixing of the fluid and the additive; and collecting the fluid and additive mixture using a calm, laminar flow.
