It is this second phenomenon that is used for generating the air microbubbles necessary for dissolved air flotation. The implementation is quite simple: the pressure of the water is increased from about 1 bar (atmospheric pressure) to a pressure usually between 4 and 6 bar and, at the same time, air is injected (at the same pressure …

The effects of coagulation-dissolved air flotation (DAF) process configuration was studied on oil refinery wastewater. The configuration was done in two ways: acid-coagulation-DAF (pre-treatment) and acid-DAF-coagulation (post-treatment). Two different cationic and polymeric organic coagulants were employed in this study to …
