When operating a belt filter, insufficient dosage leads to poor conditioning, preventing the capillary water in the sludge from converting into free water for removal in the gravity zone. As a result, the sludge remains fluid as it moves from the wedge zone to the low-pressure zone, making it unsqueezable.
