Flotation with sedimentation: Steady states and

2020-10-1  As pointed out by Stevenson et al. (2008), the flotation column shown in Fig. 1 with one inlet of gas and fluid (or suspension) works in principle as an inverted clarifier-thickener used for continuous sedimentation of a solid–liquid suspension.

Lesson 14: Sedimentation and Flotation

2008-2-6  Flotation. Suspended solids with a density close to or less than that of water can't be removed by sedimentation. Such solids would sediment only very slowly or would remain suspended. The aim of flotation is to increase the buoyancy of the solids. This is done by

Continuous harvesting of microalgae biomass using

2018-12-1  The harvesting trials demonstrated that the continuous foam flotation process operated at the optimised factors yielded RE of 95, 93, and 89% together with 173, 271 and 143-fold biomass enrichments for freshwater Chlorella vulgaris and marine Isochrysis galbana and Tetraselmis suecica microalgae respectively. However, the little reduction in the RE of the marine species was likely due to

In some cases, where it is not practicable to settle out fine particles, these can sometimes be floated to the surface by the use of air bubbles. This technique is known as flotation and it depends upon the relative tendency of air and water to adhere to the particle surface.

Microflotation Performance for Algal Separation

2013-6-24  followed by sedimentation. Flotation is often viewed as “inverted” sedimentation. The Jameson Cell (Yan and Jameson, 2004) is an induced air flotation process which also achieves high separation performance for microalgae (98%) and phosphorus. When present in effluent water, algae could be a pernicious contaminant in portable water
