Factors Affecting The Design Of Dissolved Air Flotation

Factors Affecting The Design Of Dissolved Air Flotation

Yet design of a dissolved air flotation system requires a correlation between the amount of excess gas dissolved at the elevated pressure that is, the gas that may be released and the amount of solids in the waste stream.1 Thus, the most important parameter for the design of a dissolved air flotation system is the air solids (a s) ratio. This.

1977). Dilute suspensions about 59–117 g air m−3 (3– 6 atm pressure saturation, respectively) are dissolved in the treated water (recycle) and injected into flotation cell, at 0.3–0.5 recycle feed ratio. This value is equiva-lent to about 20–30 L of air into 1 m3 of water. Con-versely, in mineral flotation or dispersed air flotation.
