Difference Between Clarifier and Thickener

2015-12-14 & 0183; The dense Thickener solids are raked to the thickener’s underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed size distribution of solids being settled or other process factors but as a general rule range from 35-50% solids by weight.
