Sludge Conditioning to Improve Filtration | Sludge Press

Generally speaking, conditioning material particles in the 10 micron range will be too small and in the 200 micron range too large to be effective for conditioning the sludge. The optimum material used for this purpose will normally consist of particles predominantly sized in the 40 to 100 micron range with 60-80 microns being ideal.
