    The volume of sludge produced, when ferric chloride was used solely, was higher compared to the use of combination of polyelectrolyte and FeCl(3).6H(2)0. The combined use of coagulant and polyelectrolyte resulted in the production of sludge volume with reduction of 60% of the amount produced, when coagulant was solely used for the treatment.

  • Chemical sludge conditioning | Sludge Processing

     · Sludge conditioning is carried out to aid the removal of the water from the solids and is most often achieved through dosing with chemicals. Conditioning coalesces (or agglomerates) the smaller sludge particles (1−10 µm) to produce larger ones and reduces the sludge colloidal (the sub-0.1 µm particle/macromolecular size) content.
