<p>The layers of this settling tank (L1, M1, L2...) define counterflow streams (V1) connected to the inlet (ED) of the settling tank and supplying concurrent streams (W1) connected to the outlet (SD) of this settling tank. Sludge coming from these two types of stream is collected in two corresponding collection tanks (BE, BS). The invention applies in particular to the purification of water. <IMAGE></p> |
