Provided are methods for monitoring a filtration and washing operation on a solid-state bulk material in a filter apparatus for cake filtration. The methods include separating a solid-state bulk material in a suspension medium using a filter element for the cake filtration, leading off the suspension medium in the form of a filtrate stream into a filtrate outlet, measuring at least one parameter value of the filtrate stream over a period of time during the filtration and washing operation, and conducting a change analysis of the at least one parameter value over the period of the filtration and washing operation to achieve the end of the filtration and washing operation and/or the effectiveness of the filtration and washing operation.

Process monitoring and control of filtration by means of filtrate measurements

The invention relates to a reflection probe for measuring properties of liquid and/or solid substances, and to the use thereof.

Reflection probe

The invention relates to an optical measurement probe for process monitoring, having a distal end, arranged in the region of a process apparatus, with a light entrance opening, and a proximal end coupled to a spectrometer, wherein a shaft comprising a light-guiding connection between the distal and proximal ends of the measurement probe is arranged between the two ends. The measurement probe is characterized in that the measurement probe has, in its distal region relative to the shaft and/or the proximal end, a reduced external diameter (FIG.).
