SLUDGE DEWATERING SNF Holding Company

The dosages for lime are between 15% and 40% of the dry content. Remarks: Lime is also used after dewatering to stabilize the sludge. The specific resistance to filtration(r) depends on the size, shape and degree of agglomeration of the solid particles that make-up the cake from a filter-press. It is independent of the sludge concentration.

US4306978A Method for lime stabilization of wastewater

A method for the lime stabilization of wastewater sludge, includes the steps of dewatering sludge so as to produce a sludge cake containing from about 10 to 60% by weight of dry solids and rapidly and intimately mixing and reacting the sludge cake with calcium oxide so as to produce stabilized sludge pellets. An apparatus for performing the process is also provided.

Lime Stabilization of Municipal Sludge Burch Hydro

The addition of lime affects the activation of polymer used for dewatering, so it is often suggested that lime stabilization occur after dewatering, which can be more difficult. Lime addition can also cause potential odor issues due to the ammonia produced and is, therefore, not ideal in areas sensitive to odors.
