Intensification of flotation treatment by exposure to vibration

by IWA Publishing  (Apr. 10, 2014)

In this paper, an intensification of wastewater flotation treatment by exposure to vibration is studied. Exposure to vibration results in the decrease of air bubble size, increase of air flow through the aerator and more even dispersion of air bubbles in water. This intensifies the aeration process, thus significantly improving the treatment ...
