Document Type and Number:
Japanese Patent JP2022141400
Kind Code:
A
Abstract:
To provide an FI measurement unit, an FI information system, an FI measurement program, etc. to reduce the work load when measuring an FI value, to reduce the size and weight of a measurement device, and to make more efficient use of the FI value for water quality control.SOLUTION: An FI measurement unit 1 includes: a water sampling passage R2 connected so as to branch to a flow passage R1 of a water treatment device 100 equipped with the flow passage R1 through which pressurized water flows; a filter 2 placed in the middle of the water sampling passage so as to be replaced by a measurer; a timer part for measuring a filtration time required for the filter to filter a target volume of water; an FI calculation part for calculating an FI value based on an equation 1 and an equation 2, when T1 denotes the filtration time measured by the timer part and T2 denotes a filtration time measured by the timer part after elapse of a certain time T after the measurement of T1; and an FI output part for outputting calculation results. [Equation 1] FI=PF/T [Formula 2] PF=100×(1-T1/T2) However, PF denotes a clogging coefficient.SELECTED DRAWING: Figure 1
