The essential characteristic of the process is the generation of two opposing currents in a restricted area, in which the downward current is by many times faster than the upward current. The current speeds can be determined by the inlet and outlet diameters. An organic flocculant is added to the suspension and pumped into a tank with a v-shaped central outlet at the bottom. In the tank suspended - partially submerged and partially towering above the tank there is a dome formed by two tubes, one inside the other. The thin sewage sludge is let into the tank through the pipe with the smaller diameter, where the speed of the current is slowed down and forced upwards, because only a superior overflow allows any run-off. Dirt particles with a specific weight higher than that of water continue sinking and collect at the bottom - in the v-shape - of the tank. From there the sludge is continuously drained and fed to the ensuing sludge drainage process . Due to metereological temperature fluctuations the rapid sedimentation tank and all of its pheriphericals shall be arranged in closed buildings. All plant operate fully automatic under SPS control.
