Abstract

PURPOSE: To properly clean a water intake filter equipment at rivers and the like by a method wherein filter unit cleaning and discharge starting are made at times based on the quantity of water intake.
CONSTITUTION: Flow meter 23 is used to measure the flow rate of water taken from river or water-takein well, water is filtered with filter unit 24 and stored in the reservoir 29. When the filter unit 24 is cleaned, cleaned water passes through discharge valve 25 and water-exhaust valve 26, is stored in discharged-water pond 29, then is discharged by dicharge-pump 28 to the outside. In this cleaning and water-discharge operation, the following procedures are used to determine cleaning timing and the discharge-water pump starting timing: The calculator processor 13 is started periodically by basic periodic command 10 and determines cleaning period 17 based on setting information 15 and flow rate of takein water 16. The cleaning time determination block 18 divides the cleaning period by the number of filter units and obtains the cleaning interval, further providing the cleaning start time of filter units based on the present time. The water-discharge pump starting time determination block 19 is made to a value at specified time before cleaning starting time, and specified time is made to a setting-information 15.
