Effect of ultrasound pulsations on suspension sedimentation
Abstract eng: The paper presents results of a gravity settling of a model suspension. Experiments have been carried out for two configurations. The first experiment involved natural gravity settling in the second case the ultrasound pulsations were introduced. Ultrasound field was provided by 20 kHz horn acting through a wall of settling vessel. Three kaolin suspensions of volume concentrations 3.8, 7.6, 11.4 % were used. It has been found that there is no significant influence of ultrasound pulsations on suspension settling. It can be stated that the ultrasound is not convenient neither for an application where acceleration of settling time is desired nor for extending off bottom suspension time.
