Test conditions, flocculation and the limits of scale-up to the plant.

Record the height of a defined interface or level, `h(t)`, during a test with documented conditions. Over an interval where the curve is approximately linear, the downward velocity can be estimated as `v_s = (h_1 -…
Sedimentation 3 min
There is no universal dosage that can be defined without considering the incoming material and the response required. The necessary dosage depends, among other conditions, on particle-size distribution, the amount of…
Sedimentation 4 min
Average velocity summarises how far an interface moved over an interval, but it does not show how that movement occurred. It can hide an initial period with little motion, changes in slope or a later transition…
Sedimentation 4 min
A repeated, comparable upstream measurement of settling response is required, together with a baseline separated by material regime and a temporal association with the subsequent thickener response. The early signal…

Scaling a result is not just a matter of increasing volume. The laboratory test and the plant may use the same tailings and flocculant while operating with different mixing, shear, dilution, residence time, solids…
Sedimentation 4 min
An automated system can record the evolution of an interface or associated signal during a test and derive a curve, characteristic times and slopes under documented conditions. It can also improve the traceability of…
