The chemical pre-treatment of sludge helps remove water upstream of thickening and dewatering processes
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.

How much is sludge worth?
The UK regulator OFWAT has introduced legislation based on the notion of sludge as a resource. Its value is often expressed in terms of calorific content, and the phosphate is also potentially recoverable. But how exactly should sludge value be quantified?
