    摘要: The invention relates to a static decanter (D) for prethickening liquid sludge in a water treatment plant, in particular wastewater, comprising an inclined bottom (8), the decanter being provided with a liquid sludge supply pump (13), a device for injecting a polymer in the liquid sludge, an overspill discharge (23) and a pump (26) for extracting the prethickened sludge from the decanter. The decanter further includes a means for accelerating the sludge decantation, a means (M) for adjusting the concentration of suspended material in the prethickened sludge at the outlet, and capable of maintaining the concentration of the prethickened sludge extracted from the decanter at a substantially constant level despite the concentration variations at the inlet, and a means (M3) for adjusting the level of the sludge blanket (V) and capable of maintaining said level at the lowest possible level.
