Abstract
Systems and methods for dosing slurries to remove suspended solids from the slurry are disclosed. The systems and methods may be used to dewater slurries having relatively high solids content such as earthen slurries. In some embodiments, the zeta potential of the slurry is monitored by an electroacoustic zeta potential sensor to control coagulant addition.
