摘要：

The application of the conventional flotation column to wastewater treatment has failed to realize its full potential, mainly because of inadequate mixing (or backmixing) and non-uniform dispersion of bubbles in the column. Thus, the challenge lies in the development of a mechanical design, which can provide proper hydrodynamic conditions that will result in efficient separation, with high throughput. This paper describes a new column design, in which multiple draft tubes were used. Test results demonstrate that this new design is superior to that of the conventional flotation column for wastewater treatment.
