    摘要： A method for treating liquid-waste utilizing carriers having microorganisms immobilized thereon employs an aerobic treatment tank. At least one underwater agitation type aeration apparatus having an air-diffusing mechanism on a discharge side of an impeller is provided in the treatment tank. While supplying atomized air into the liquid-waste, the carriers and the liquid-waste are circulated through the treatment tank by the underwater agitation type aeration apparatus, to thereby substantially uniformly distribute the carriers in a floating state in the treatment tank. The discharge opening of the underwater agitation type aeration apparatus is provided in the vicinity of a bottom surface of the treatment tank or at an intermediate position with respect to the depth of liquid in the treatment tank. In the latter case, the underwater agitation type aeration apparatus sucks the carriers and the liquid-waste in the vicinity of the bottom surface of the treatment tank through a draft tube extending from the underwater agitation type aeration apparatus toward the bottom surface of the treatment tank.

    摘要： In a small scaled plant intended for flexible manufacturing, a pure water supply system is provided at a low cost without reducing a production efficiency. A pure water system produces a plurality of grades of pure water which are supplied through pipes connected to points of use for cleaning, CMP, lithography, and the like. Upon receipt of a request signal from each point of use for starting to use a certain grade of pure water, a controller determines whether or not a required amount exceeds the capacity of the grade of pure water which can be supplied by the pure water system. If not, the controller sends a use permission signal to the point of use for permitting the same to use the pure water. When a certain use point is using the requested grade of pure water, the controller may not permit the requesting point of use to use the pure water until a use end signal is sent from the use point which is using the pure water.
