WebThis clarifier separates suspended solids from wastewater by sedimentation at a high water linear velocity of more than 4 m/h (four times higher than conventional clarifiers). It can reduce construction costs by reducing the diameter and height of the tank. Web16 de jun. de 2024 · In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.
