Abstract: A water treatment control system using a fluorescence analyzer includes an activated carbon injection equipment 4 having an activated carbon injector 4a, a fluorescence analyzer 7 provided on the upstream of the activated carbon injector 4a, and a flowing water flowmeter 6. An activated carbon injection rate necessary to reduce a trihalomethane formation potential is calculated by an activated carbon injection rate calculating apparatus 8 based on a measured value from the fluorescence analyzer 7. An activated carbon injection amount from the activated carbon injector 4a is controlled by an activated carbon injection amount control apparatus 9 based on the activated carbon injection rate and a measured value from the flowing water flowmeter 6.

Abstract: A water treatment control system for minimizing trihalomethane formation includes chlorine injection equipment having a plurality of chlorine injectors (11d, 12, 13), a fluorescence analyzer 7 provided on the upstream of the chlorine injectors, and a water flowmeter 6. An chlorine injection rate necessary to reduce a trihalomethane formation potential is calculated by a chlorine injection rate calculating apparatus 14a based on a measured value from the fluorescence analyzer 7. An chlorine injection amount from the chlorine injectors is controlled by chlorine injection amount control apparatuses 15a–15c based on the chlorine injection rate and a measured value from the flowing water flowmeter 6.

Abstract: A wave-power generator assembly including a pair of one-way turbines symmetrically mounted on a common rotating shaft is provided. Because of the symmetrical arrangement of the one-way turbines, the rotating shaft and, therefore, bearings to rotatably support the rotating shaft are prevented from receiving excessive thrust forces. Thus, the present generator assembly may be presented to service for an extended period of time without requiring replacement of parts.
