Dewatering Equipment And Lime Stabilization

WasteWater System: Sludge Disposal: Lime Dewatering. Stabilization of wastewater sludge using lime is a common method applied to eliminate growth of pathogens and to get rid of undesirable odor prior to dewatering and disposal.There are basically two types of procedures involved in the stabilization process, whereby one is through addition of lime just before dewatering and another is after ...
