摘要： A dissolved gas flotation apparatus (10) comprises: - a flotation tank(18) having an upstream contact zone separated by a baffle (9) from a downstream clarification zone; - one or more pressure reduction nozzles (28) arranged to discharge into the contact zone of the flotation tank (18); - a flow-straightening arrangement including two or more plate-like barriers (104) in the contact zone of the flotation tank (18), wherein: each barrier (104) has walls, the walls of the barriers (104) together defining flow paths in a desired direction; and each barrier (104) provides a barrier to horizontal flow perpendicular to the desired flow direction.

摘要： A dissolved gas flotation apparatus (10) comprises: - a flotation tank (18); - one or more pressure reduction nozzles (28) arranged to discharge into the flotation tank (18); - an underflow exit baffle (19) defining the upper part of an exit channel (70) from the flotation tank (18); and - a plurality of flow-contacting members (44) arranged within the flotation tank exit channel. The flow-contacting members (44) may include one or more of vanes; bubble- forming members; bubble-capturing members; bubble-coalescing members; turbulence-introducing members; flow-redirecting members; pressure-increasing or pressure-decreasing members; members which introduce a pressure difference in the flow; and velocity-increasing or velocity-decreasing members.
