Industrial sludges applied to a centrifuge are typically conditioned with what substance?

Industrial sludges are typically conditioned with polymer to improve the efficiency of the centrifuge process. Polymers are long-chain molecules that can help to enhance the separation of solid and liquid components in the sludge. By applying a polymer, the surface properties of the sludge particles are modified, promoting agglomeration and increasing the size of the floc, which aids in the dewatering process during centrifugation.

The use of polymer is effective because it helps to bind the small particles together, making them easier to remove from the liquid phase. This process leads to a better yield in terms of solid recovery and reduces the moisture content of the generated cake.

Although flocculants are also used in sludge treatment, the specific choice of polymer as a conditioning agent highlights its role in enhancing the separation process in centrifuges, making it the most appropriate answer in this context.
