2020-05-04· Ratio of concentration can be thought of as the number of tons of feed required to produce 1 ton of concentrate. The ratio, K, for a separation can be obtained directly from the product weights or from the product assays if the weights are not known: K = F /C = (c — t)/(f-t) = the concentration ratio. At operating plants, it is usually simpler to report the K based on assays.

Air flotation is a solid-liquid separation process that utilizes up-flow microbubbles to thicken activated sludge and enhance clarification efficiency. Continuous air flotation experiments were performed to investigate the effect of operation parameters such as initial MLSS (mixed liquor suspended solid) concentration, air pressure, surface loading rate, air to solid (A/S) ratio, and flotation

Dissolved Air Flotation an overview ScienceDirect Topics

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.
