Sludge settling velocity

Webb12 aug. 2014 · If the floc settles rapidly but leaves pin floc in solution or fine floc floating on the top, it indicates an "old sludge". In the secondary clarifier this results in undesirable turbidity and TSS passing into the effluent. As a result, you should increase wasting rates. WebbThe settling velocity of the particles ranged from 0.24 to 0.80 mm/s, with an even distribution as described in reference . At the boundaries, the particles either escaped through the outlet, which was reflected in the wall shadow zone, or became trapped in the wall zone of the lamellae or at the bottom [ 31 ].
