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. http://www.wefnet.org/OTWT/Chapter%203%20%20Primary%20Treatment.pdf
