Sludge conditioning

Introduction to sludge conditioning

Sludge thickening and dewatering processes normally require pre-treatment to assist the separation of the water from the solids. This pre-treatment is referred to as conditioning, which takes the form of either:

• chemical conditioning, by dosing with inorganic coagulants (such as iron or aluminium) and/or organic flocculants (or polymers), or
• thermal conditioning by heating the sludge under controlled conditions.
