    Evaluating the suitability of two mud level sensing technologies for juice clarifiers : final report 2020/201
    (Sugar Research Australia Limited, 2021) Stobie, R; Abdi, A
    Mud level measurement using sensors in juice clarifiers is a challenge for Australian sugar mills. Measurement of the mud/juice interface is typically by manual means and the operator must visually locate the position of the interface through sight glass windows and make adjustments to either mixed juice feed rates or mud filtration rates to keep the interface at a ‘safe’ operating level. High level excursions can cause carry-over of mud particles into the clarified juice (with subsequent impact on evaporation and crystallisation). If the interface is too low, then rat-holing of juice to mud can occur (impacting mud filtration and increasing filtrate recycle). Sugar mill juice clarifiers present a harsh environment for in-situ interface monitoring owing to the high temperature (100℃), varying populations of suspended floc particles, relatively fine density profiles and rotating equipment inside the vessel.
