It has been established on the basis of the mathematically rigorous determination of the stability of a separation process that an increase in the duration of quasi-stationary conditions can be increased as a result of transitions between stationary hydrodynamic regimes. The boundaries of the region of weak turbulence, in which stability of a separation process as a function of the geometric characteristics of the apparatus, the physicochemical properties of the suspensions, and the stochastic parameters of the suspensions is possible, have been determined. The possibility of significant (by a factor of 2.5-3) intensification of a separation process in a thin-layer sedimentation tank without alteration of its geometric characteristics has been revealed. The results of this work were employed for intensifying the operation of the thin-layer sedimentation tanks already in units for the local purification of industrial waste water in plant in Dzerzhinsk.
