Microbubble Formation by Electrolysis Using a New Mixing Equipment with Low Frequency Vibratory Fins

Abstract

By electrolysis of water using new mixing equipment with low frequency vibratory fins, microbubbles of oxygen and hydrogen were produced for NaOH electrolyte. The effects of operating parameters of the mixing device, that is, vibrating frequency of fins, concentrations of electrolyte and electrolysis current on the average bubble diameter, bubble size distribution and gas holdup were investigated. This operation shows a new microbubble generation method.
