2022128 · We made a systematic review of the DAF technique in wastewater treatment in 2015-2021. We reviewed six indexed databases and governmental statistical reports; we used the keywords: dissolved air flotation, microbubbles, wastewater treatment, and the main operating and design parameters involved in the effectiveness of the …
view moreFroth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are obtained. Practically …

view moreThis paper* presents a physical-mathematical model for dissolved-air flotation (DAF). The flotation model is an important aid for gaining insight into the effect of design parameters such as bubble diameter, particle size, bubble-volume concentration, contact time, temperature and surface load. The results with the flotation model were compared ...
