Abstract
An apparatus and method are disclosed for environmental applications such as waste water treatment, de-inking of recycled paper, chemical/biochemical waste clean-up, and mineral beneficiation, using a multi-stage flotation column. A series of draft tubes arranged axially and separated by baffles provides individual mixing stages in the flotation column and a special gas distributor generates fine gas bubbles. The draft tubes create repetitive loop flow of the feed fluid in each flotation stage. This provides uniform distribution of the gas bubbles throughout the column and significantly enhances mixing and contacts of the gas bubbles with the impurities to be removed.
