Sludge Bulking

The Biological Sludge which does not settle well and compacts poorly in the secondary settling tank , leaving a small amount of clear supernatant at the top is Bulking Sludge. Bulking occur due to the presence of toxic substances , insufficient aeration , frequent shock loadings and excessive rate of supply of substrate. Bulking of Sludge is controlled by a mixture of copper sulphate and lime in 1:1 ratio by weight
