Laboratory-scale biosolids dewaterability assessment for municipal water resource recovery facilities
Dewatering is an important operational component in water resource recovery facilities (WRRFs) to reduce conveyance costs by volume reduction of sludge (wet solid residuals). Cake solids are the agglomerated solids product of dewatering. Cationic polymers are the typical chemical conditioner used to destabilize solids during dewatering to increase the rate and extent of water release from a solids slurry. Dewatering is a costly endeavor for Metro Wastewater Reclamation District, and process upgrades are expected to affect dewaterability. Laboratory-scale dewatering methods that provide cake ...
