Constrained model predictive control of an industrial high-rate thickener

Abstract. High-rate thickeners are used in the mining industry to improve water recovery from slurries and increase their solids ratio. High-rate thickeners operate under strict constraints and several disturbances. To control this process, a constrained m odel p redictive c ontrol (MPC) is developed in this paper.

Sizing a high rate thickener

To my mind in a high rate thickener, solids concentration during flocculation is a powerful tool and we have to choose the solids concentration to achieve maximum flux concentration. In this condition selecting a safety factor would led to overcome variation in feed properties (e.g. solids concentration) and a wise design would be achieved.

Beginners guide to thickeners

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.

High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.
