  • Two dewatering of slurries controlled by video system
    Patent number: 5380440
    Abstract: A process for dewatering a slurry, which comprises introducing a dewatering aid into a slurry of solids in water to condition the slurry. The conditioned slurry is then passed into a filtration zone where water is filtered off from the solids. Images of the dewatered solids are recorded with a video camera and digitized. The recorded images are compared with digitized desired images representing desired moisture levels. The recorded images versus the desired images are converted into analogue signals which are indicative of the moisture content of the dewatered solids.
