There is provided a microbubble generating method including: supplying a gas to a rotatorwhile rotating the rotatorin a liquid; injecting the gas into the liquid from bubble injection holes formed in the surface of the rotator; and applying a shear force, produced by the relative movement between the liquid and the rotator, to gas bubbles present on and in the vicinity of the surface of the rotatorto generate microbubbles. The microbubble generating method can easily generate a large amount of microbubbles without forcibly creating a swirling flow of fluid.

Microbubble generating apparatus and method

A liquid cyclone is configured for inflowing raw water containing impurities as targets of collection to be forced to swirl inside to spin down impurities contained in raw water, an inflow pipe is connected with an upper portion of the liquid cyclone to supply the liquid cyclone with raw water, and configured for supplied raw water to be forced to swirl inside the liquid cyclone, a connecting portion is connected with a lower portion of the liquid cyclone, and configured with a discharge port to discharge spun down impurities from the liquid cyclone, an impurity collector is connected to the liquid cyclone with the connecting portion in between, and configured to collect impurities discharged from the liquid cyclone, an obstacle is disposed in or near the discharge port, , and configured to prevent impurities collected in the impurity collector from backing up into the liquid cyclone, and an outflow pipe is connected with a top portion of the liquid cyclone, and configured for raw water having got rid of impurities to outflow as treated water from the liquid cyclone, whereby impurities separated from raw water is prevented from being re-mixed in raw water, allowing for an enhanced separation performance.

Solid-liquid separator

An activated carbon adder adds activated carbon to raw water before flocculating sedimentation, to adsorb suspended matter contained in raw water, a liquid cyclone is adapted to separate activated carbon with suspended matter adsorbed thereon, from raw water containing activated carbon, an inflow line is connected with the liquid cyclone so as to cause raw water containing activated carbon before flocculating sedimentation to flow into the liquid cyclone and swirl therein, an activated carbon discharge line discharges activated carbon spun down out of raw water containing activated carbon in the liquid cyclone, from the liquid cyclone, and a pretreated water discharge line discharges raw water having got rid of activated carbon as pretreated water from the liquid cyclone, allowing for a reduced amount of chemicals to be used, with production of a reduced amount of sludge.

An antenna module capable of finely adjusting the resonant frequency and having an antenna element exclusively used for radio transmission and reception to provide a broad frequency band characteristic. This antenna module is composed of a dielectric substrate molded in a predetermined shape, a grounding conductor in the form of sheet provided on one surface of the dielectric substrate, and antenna element conductor in the form of sheet provided on the opposite surface to the above one surface and having end portion being almost V-shaped end folded, and an adjusting member inserted into the almost V-shaped folded end portion.
