Water treatment control system using fluorescence analyzer

Abstract

A water treatment control system using a fluorescence analyzer includes an activated carbon injection equipment 4 having an activated carbon injector 4 a , a fluorescence analyzer 7 provided on the upstream of the activated carbon injector 4 a , 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 4 a 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.

1 - 9 . (canceled)  
   
   
       10 . A water treatment control system using a fluorescence analyzer comprising: 
 a membrane filtration apparatus for separating and removing a turbid substance in a water to be treated;    a fluorescence analyzer for measuring a relative fluorescence intensity of the water to be treated; and    a membrane filtration operation control apparatus for operating and controlling the membrane filtration apparatus based on the measured value of the fluorescence analyzer.    
   
   
       11 . The water treatment control system using a fluorescence analyzer according to  claim 10 , 
 wherein the fluorescence analyzer consists of a pair of analyzers provided on both upstream side and downstream side of the membrane filtration apparatus, and the membrane filtration operation control apparatus operates and controls the membrane filtration apparatus based on the measured values from the pair of analyzers.
