Circular dissolved gas flotation system

摘要

A circular dissolved gas flotation system is provided for increasing the loading rate with increasing size flotation basins. The dissolved gas flotation system includes a submerged annular release chamber located about the periphery of the flotation basin for peripherally introducing particle-carrying liquid and gas bubbles uniformly into the flotation basin. The release chamber defines a continuous slotted opening substantially about the length of the release chamber. The size of both the slotted opening and the cross-sectional area of the release chamber are reduced from the divider baffle to the splitter baffle to uniformly distribute the flow about the periphery of the flotation basin. The release chamber includes a divider baffle to split the input flow in opposite directions tangentially about the length of the release chamber, and a splitter baffle to prevent the two tangential flows from converging.
