Metso is launching a pre-engineered high-rate thickening solution, the HRT-S, which, it says, will allow significantly shorter delivery times.

The HRT-S complements Metso’s existing high-rate thickener product family which consists of the HRT and HRT-S products. The HRT-S thickener is part of Metso’s Planet Positive offering, enabling savings in power consumption, a reduction in embedded carbon and decreased maintenance costs, Metso says.

Esme Pelser, Product Manager for High Rate Thickeners at Metso, said: “Built upon the perfected HRT technology, which has been available for decades, the HRT-S uses bench-scale and pilot testing to ensure process performance guarantees. With a defined set of features and selected options to choose from, the modular HRT-S enables accelerated project deliveries and shorter installation times.

“The HRT-S is easy to operate and service. We are excited to introduce the full range with options up to 35 m diameter by the end of this year.”

The HRT-S comes with Reactorwell™ technology, which is the new generation feedwell with high solids retention and mixing efficiency that, Metso says, eliminates feed short-circuiting. It also offers low shear rate for ideal floccule growth, even discharge symmetry and excellent feed preparation.
