Effects of froth properties on dewatering of flotation ...

Aug 15, 2020  For dewatering of flotation products, filtration is the most commonly used technology which uses various driving forces, such as vacuum, pressure and centrifugal forces, to separate liquid from solids (Hogg, 2000, Tao et al., 2000a, Tao et al., 2000b, Concha, 2014).In many plants, thickening is also applied prior to filtration to reduce the amount of water to be removed by filtration, which ...

Sludge treatment − dissolved air flotation Sludge ...

Jun 18, 2020  How DAF works. Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling.
