Here, the impact of fast-filtering compressible materials on the throughput of fixed-chamber filter presses is explored. The dewatering properties for a compressible yet highly permeable minerals processing slurry are used as inputs to a filter press model to explore the effects of operating and design parameters. For fast-filtering materials, maximum throughput is achieved with wide cavities and minimal handling time, while membrane resistance can be significant. Pressure affects the maximum achievable concentration, as given b..View full abstract
