The efficiency of impulse drying sludge is optimum at about 30% ingoing solids for a paper mill primary sludge. At lower solids, the sludge matrix is probably too closed for pressure dewatering to effectively occur. At higher levels, the surface water may be depleted to the point where sufficient steam is not generated. For a mixed sludge, impulse dewatering is relatively insensitive to polymer dosage, with low polymer levels providing the best results.
