A new soft-sensor was developed to measure a hydraulics pressure gradient in a liquid-solid fluidised bed (LSF). LSF is frequently encountered in drinking water treatment processes, often to obtain a large liquid-solid interfacial surface area. A large surface area is crucial for optimal seeded crystallisation in full-scale softening reactors. Due to crystallisation, particles grow and migrate to a lower zone in the reactor which leads to a stratified bed. Larger particles adversely affect the surface area. To maintain optimal process conditions in the fluidised beds, information is needed about the distribution of particle size, local voidage and available surface area, over the reactor height. This data set contains 54 individual measurements of calciet pellets (0.8-0.9mm), (0.9-1.0mm) and a mixture (0.5-0.63mm+1.25-1.4mm) and 3 mm glass beads for various water flow rates.
