Title:
WATER QUALITY IMPROVING UNIT AND WATER QUALITY IMPROVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/125996
Kind Code:
A1
Abstract:
A water quality improving unit (1) and a water quality improving device which
enhance water transparency by removing organic matters allowed to float on the
water surface with micro-bubbles (X2) attached, and can improve water quality
by balancing dissolved gases such as oxygen gas and nitrogen gas. The water quality
improving unit comprises a unit body (2) having a hollow portion formed almost
rotationally-symmetric and reduced in diameter toward the both axial directions
of the rotationally symmetric axis, a liquid introducing hole opened in the peripheral
wall of the unit body (2) in a tangential direction, vertically-directed gas-liquid
jet holes (3) disposed to be opened in a vertical direction along the axial direction
of the rotationally symmetric axis of the hollow portion, and respectively provided
in the both diameter-reduced portions of the hollow portion, a frame-carrying
pipe (4) connected with the upward-directed gas-liquid jet hole (3) with some
gap between them, and a liquid bubble generating container (6) connected with
the upside unit body (2) portion in order to form liquid jetted from the upward-directed
gas-liquid jet hole (3) into a cluster (a bubble cluster in a soap bubble form)
of liquid bubbles (X3).
