ABSTRACT:
A process and apparatus for the treatment of pre-concentrated solid-liquid mixture streams, and in particular the dewatering of solid-liquid mixture streams metering the mixture from an intermediate container to a liquid separation device. The process accounts for variable inlet conditions or parameters of the solid-liquid mixture stream which is supplied to the intermediate container. A preset metering stream volume of the mixture is supplied to the liquid separating device for separating liquid by a metering device as a function of the level of the mixture in the intermediate container. The metering device can optionally comminute the solid-liquid mixture stream to be treated. The throughput rate of the liquid separating device is automatically adjusted according to the conveying rate of the metering device.
