| 摘要 |
<p>The invention concerns a process for flocculation, precipitation, agglomeration, or coagulation of dissolved, colloidally dissolved, suspended, or emulsified substances or microorganisms contained in a liquid and a device for implementing the process. The liquid is exposed to one or more fields of stationary ultrasonic waves the frequency f of which is greater than one-seventh of a threshold frequency fo which is a function of the kinematic viscosity of the liquid and of the effective radius of the particles present in the liquid. The device has an acoustic irradiation tank which contains the fluid to be cleaned and is provided with an ultrasonic converter which directs the ultrasonic radiation on to an opposing reflection surface.</p> |
