High-rate thickener: maximise throughput and water recovery

May 27, 2026

Recover more process water and keep your circuit moving. The FLS High-rate Thickener delivers high-capacity solid-liquid separation in a compact footprint, so your operation thickens more slurry, reclaims more water and produces a denser, more consistent underflow.

By design, a high-rate thickener handles far higher throughput than a conventional thickener of the same size (FLS cites up to around 12 times), which means more capacity from a smaller footprint and lower overall cost.

What the High-rate Thickener helps you do:

- Recover more process water for reuse across the operation

- Produce a denser, more consistent underflow

- Reduce footprint and overall cost in dewatering and tailings management

Part of the full FLS dewatering range, backed by process knowhow, lifecycle service and global support.
