The apparatus includes a tank of steel, or concrete, into which the liquid to be treated is introduced vertically through a centrally located inlet at the tank bottom. Disposed inside the tank, above said inlet, are a tubular venturi-type eductor member and a conical partition member which defines a liquid mixing, coagulating, flocculating and sludge recirculating zone. As the entering liquid flows through the eductor, it draws in a very large volume of surrounding sludge to establish a high degree of sludge recirculation and mixing.
