This is illustrated in Figure 9 for a 2-cell bank where the total cell volume is fixed but the volume of each cell is altered, which is equivalent to changing cell recovery Setting total bank recovery when cells are equal volume (V 1 /V 2 = 1) at 75%, we note that all other volume combinations give less than 75%

top of a flotation cell determines the amount of froth surface area for a given flotation cell During the project design phase, the optimum amount of froth crowding is determined using design data from the customer in conjunction with the accepted Froth Carry Rate guidelines above, and experience of particular applications By adjusting

Here is the conventional wisdom: If 70 percent of a tank’s storage capacity falls below the flood level, anchor the tank At the same time, if the water table periodically rises to a level above the bottom of the excavation or if the region is subject to periodic heavy rains, fire codes require that flotation be prevented

Typical values of the friction coeffficient (f) from the literature generally range between 35 for silts and 55 for coarse- grained gravels against concrete The friction coefficient is a function, however, of soil material type, manhole material, outside manhole profi le, compaction levels, and material homogeneity

The ultimate carrying capacity of a flotation system for the treatment of a given feed is realized when the maximum bubble surface area rate at the top of the cell is provided through the adjustment of the appropriate operating parameters such as aeration rate and frother concentration

A mortar bed between the two surfaces is recommended To design the mechanical connection between the anti-flotation sstone and the structure, the net upward force must be calculated This calculation can be achieved by multiplying the buoyant force by the FS, and subtracting the downward force Increase member thickness
