Intensification of Chemical Agents Mixing by Vibroacoustical Agitation

Abstract

This article describes a set of experiments that aim intensification of the processes of coagulation and flocculation for waste water treatment by enhancement of reagents' mixing efficiency using vibroacoustical agitation. The apparatus for vibrational mixing is a cylinder with a perforated piston, which performs a sine movement at frequencies 6–100 Hz. It is shown, that the highest mixing efficiency was achieved at piston’s eigen frequencies. Mixing time was 20 s. The proposed method shows high mixing equality and lack of dead zones in the apparatus, when compared to other methods.
