Chemical conditioning (i.e. adding coagulants and/or flocculants) or thermal conditioning (i.e. heating) to improve the conditions during sludge thickening/dewatering.
Not applicable to inorganic sludges. The necessity for conditioning depends on the sludge properties and on the thickening/dewatering equipment used.
(b)
Thickening/dewatering
Thickening can be carried out by sedimentation, centrifugation, flotation, gravity belts, or rotary drums. Dewatering can be carried out by belt filter presses or plate filter presses.
Generally applicable.
(c)
Stabilisation
Sludge stabilisation includes chemical treatment, thermal treatment, aerobic digestion, or anaerobic digestion.
Not applicable to inorganic sludges. Not applicable for short-term handling before final treatment.
(d)
Drying
Sludge is dried by direct or indirect contact with a heat source.
Not applicable to cases where waste heat is not available or cannot be used.
