Title:
METHOD FOR OBTAINING INFLOW OF RAW WATER IN BATCH WATER TREATMENT APPARATUS
Document Type and Number:
Japanese Patent JP3512378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the inflow of raw water to a batch water treatment apparatus without using an expensive flow meter.
SOLUTION: The total quantity of the raw water pumped into a flow rate adjusting tank 12 from a raw water tank 11 by a raw water pump P1 in the sampling cycle of a necessary time width in which mass balance is established so as to equalize a water quantity flowing into the tank 12 to a water quantity discharged from batch tanks No.1 and No.2 is divided by a total working time during which the pump P1 in the sampling cycle to obtain the discharge Qi [m3/h] of the pump P1. Then, the inflow of the raw water QIN [m3] is obtained by the product of the discharge Qi of the pump P1 and the actual working time Ti [h] of the pump P1.
