ABSTRACT:
A method and apparatus for the quantitative recovery of solids suspended in a fluid from such fluid involving continuous flow centrifugation. Samples of the fluid with the particles suspended therein, are simultaneously pumped from a plurality of source locations into a common chamber wherein they become mixed while being continuously fed thereto. The samples from the mixing chamber flow to a sample splitting chamber from which a portion is diverted to a continuous flow centrifuge and the remaining diverted to waste. The quantity of mixed sample fed to the centrifuge is determined so that the quantity of solids collected in the centrifuge can be related thereto. The apparatus includes a plurality of pump units, each having a water inlet and a water outlet, a sample mixer consisting of a chamber having inlets thereto for receiving the water samples from the pump units. The sample mixer communicates directly with a sample splitting chamber having a first outlet open to atmosphere and a second outlet downstream thereof which is connected to the inlet of a continuous flow centrifuge.
