Flotation in Water and Wastewater Treatment

Flotation in Water and Wastewater Treatment

Flotation constitutes a separation process that originated from mineral processing. Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or sorptive flotation.

A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation DGF units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles.
