Abstract

Electroflotation (EF) is the flotation using electrolytically generated bubbles of hydrogen and oxygen for separating suspended substances from aqueous phases. This process was first proposed by Elmore in 1905 for flotation of valuable minerals from ores. Compared with the conventional dissolved air flotation (DAF), EF has many advantages, including high flotation efficiency, compact units, easy operation, and less maintenance. Therefore, EF is an attractive alternative to DAF. This technique has been proven very effective in treating oily wastewater or oil-water emulsion, mining wastewater, groundwater, food processing wastewater, restaurant wastewater, industrial sewage, heavy metals containing effluent, and many other water and wastewaters.
