Andritz recently introduced its Metris addIQ RheoScan, an optical measurement system for automatic polymer dosage in belt presses and gravity belt tables. Among other features, the system now uses artificial intelligence (AI) to further increase process stability and reduce operating costs. Metris addIQ RheoScan measures the actual sludge conditions throughout the thickening and dewatering stages in real time using a convolutional neural network for texture detection. The system adjusts the polymer dose as needed to match changing flow rates and sludge conditions — automatically and with the utmost precision. This allows for almost fully autonomous machinery operation. The new squeeze-control option enables the system to operate at the capacity limits of the machine 24/7, effectively eliminating downtime.
