Abstract
A dissolved gas flotation system including a flotation cell having an inlet and an outlet defining a direction of flow along a longitudinal axis extending from the inlet to the outlet. The flotation cell has a top and a bottom to define a cell depth extending from the top of the flotation cell to the bottom of the flotation cell in a direction of a transverse axis transvers to the longitudinal axis. A first means discharges a first dissolved gas and bubble mix in a first direction adjacent the inlet; and a second means discharge a second dissolved gas and bubble mix in a second direction adjacent the outlet counter-current to the first direction.
