1. A system for dosing a slurry to remove suspended solids, the system comprising:
a dosing vessel for adding a dose of additive to the slurry;
one or more transducer devices that generate an acoustic wave that is transferred to the slurry, the one or more transducer devices detecting (1) an acoustic property of the slurry and (2) an electroacoustic property of the slurry;
an additive control system for controlling the dose of one or more additives added to the dosing vessel, the additive control system comprising:
an additive feed system for introducing the dose of additive to the dosing vessel; and
a controller configured to:
calculate a specific surface area of the slurry based at least in part on the acoustic property of the slurry; and
control the dose of additive added to the dosing vessel from the additive feed system based at least in part on (1) the specific surface area of the slurry and (2) the electroacoustic property of the slurry, wherein the one or more transducer devices detect the electroacoustic property of the slurry after generation of the acoustic wave.
