Pilot‐plant studies of non‐steady‐state continuous sedimentation: hydrodynamics and solids distribution profiles
Résumé
A sedimentation‐flocculation pilot plant has been designed and built, capable of operating under continuous and discontinuous conditions, incorporating a system to detect solids concentration profiles throughout the settler using electrical conductivity, and an automatic control device, supported by suitable computer equipment with its own software. The hydrodynamic behaviour of the continuous thickener has been studied through transient‐response techniques. Results of experiments carried out with mineral suspensions in continuous operation are presented here.
