Change in ζ-potential of aquatic environment in ultrasonic field

Summary

At the boundary of the adsorption layer of the micelle an electrokinetic potential arises named ζ-potential. The numerical value of ζ-potential produces a significant impact on the processes that occur during water treatment, namely, coagulation and sedimentation. The influence of ultrasonic cavitation on the change in ζ-potential of aquatic environment is considered. Ultrasonic equipment and instruments for determining ζ-potential are presented. Experimental data on the effect of ultrasonic field on the electrophoretic mobility of particles in water is presented. The dependence of ζ-potential on the duration of ultrasonic treatment is obtained. The conducted experimental studies confirm the use of the ultrasonic method of water treatment for the enhancement of water treatment processes.
