1°) continuous 2°) batch Continuous flotation The unclarified must is fined in-line then passed through the flotation cell, where it is saturated with gas. It is then sent to a flotation vat, where the deposits, combined with the gas, are suctioned or scraped off the surface, depending on their viscosity. The

Flotation - ScienceDirect

Jan 01, 2016  Continuous flotation cannot be performed in a single cell because of losses due to short circuiting of pulp between feed inlet and pulp outlet. It is therefore usual to use 4–12 cells in series. This also increases the residence time of the particles in the cells, giving the slow floating particles a chance to report to the froth layer. Cells ...

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.

TECHNICAL PAPER Secondary Produced Water Treatment

A major difference between induced gas flotation and micro bubble flotation exists in the size of the gas bubbles in the liquid. MBF uses bubbles that are 5-50 microns (10 micron nominal) in diameter. These smaller bubbles, approximately one trillion per cubic foot, allow for a greater total number of bubbles and this creates a higher
