Abstract
A method is provided for continuously clarifying a flowable suspension with a discontinuously solid-discharging—self-discharging—separator, which has a rotatable drum with a vertical axis of rotation, a feed for the suspension to be clarified and at least one liquid discharge for continuously discharging at least one clarified liquid phase, and discontinuously openable solid-discharge openings for discontinuously discharging the solid phase. The method involves a) measuring one or more of the suspension parameters mass, mass of solid substance in the suspension, mass flow, temperature, density, cumulative density; and b) initiating a time-limited discharge of solid substance as a result of a repeated determination on the basis of step a) in the event of or after the exceeding of a limit value.
