Flotation aid and process for removal of impurities

During a flotation process the flotation aid is added to a mineral slurry during a pre-conditioning procedure, as described in detail below. To insure maximum effectiveness, the pH of the slurry during the pre-conditioning procedure is preferably maintained at 4.0 or higher, and more preferably above 7.0.

Flotation Process - an overview ScienceDirect Topics

In flotation process, the gas or air bubbles are introduced through culture suspension, and the microalgal biomass get attached to gaseous molecules and accumulated on the liquid surface. This method is particularly effective for thin microalgae suspension that could be simply gravity thickening.

Flotation: As Primary Treatment of Waste Water

2 天前  To aid in the flotation process, chemical coagulants such as aluminum and ferric salts or polymer coagulant-aids are often used. These chemicals increase the flocculent structure of the floated particles so that they can easily entrap the air bubbles. Two methods of flotation are currently available:

Dissolved Air Flotation - an overview ScienceDirect

Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
