PURPOSE: A hybrid type aerating system is provided to prevent the over-aeration of micro-bubbles and excessive increase of dissolved air by installing a micro-bubble aerating pipe at the lower side of a coarse-bubble aerating pipe. CONSTITUTION: A main pipe(106), a coarse-bubble aerating pipe(102), a micro-bubble aerating pipe(104), conduits(108, 110), and a valve(112) are arranged. The coarse-bubble aerating pipe generates coarse-bubbles. The micro-bubble aerating pipe is installed at the lower side of the coarse-bubble aerating pipe and generates micro-bubbles. A first conduit connects the main pipe and the coarse-bubble aerating pipe. A second conduit connects the main pipe and the micro-bubble aerating pipe. The valve is installed at the first conduit. |
