The effects of salinity and other factors on flocculation settling are investigated in this paper. The many-body hydrodynamic interactions and XDLVO potential between sediment particles are taken into consideration. The effects of salinity, sediment concentration, Hamaker constant and hydration on settling speed are analyzed. The obtained fitting formula for flocculation settling speed accords with computational and experimental results and is of referential importance.
