Algae Removal Using Dissolved Air Flotation

Algae removal using dissolved air flotation W. F. Rance Bare, Norman B. Jones, and E. Joe Middlebrooks The separation of algae from their growth media, whether it is one of the steps in reclaiming water for reuse or a step in the harvesting of algae for use as a food, has proved a difficult and costly operation.13 Some of the reasons for the

Flotation removal of algae from water - ScienceDirect

1998-10-15  The dispersed air flotation process was utilized to remove algae (Scenedesmus quadricauda) from water.Three types of collector, cationic N-Cetyl-N-N-N-trimethylammonium bromide (CTAB), anionic sodium dodecylsulfate (SDS), and the nonionic Triton X-100 were used and compared.It was observed that ca. 10% of algae removal was achieved when SDS and Triton X-100 were used,
