Abstract

PURPOSE: To make it possible to make the turbidity of processed water below a set value by decreasing the working ratios of filters by controlling the ratio of the distribution of a branch side for unprocessed turbid water by exercising control over the start and stop of filters, to which water is branched, as many times as fixed.
CONSTITUTION: Feed turbid water A of turbidity D0, received from piping 1, is led to feed water tank 7 via flow rate control valve 5 and then sent to process tank 12 via process piping 8 and filters 10 before being supplied from discharging pipe 15 and water pump 16 to the next stage. Then, turbid water A branched by valve 5 is led to process tank 12 via pipe 14 and microcomputer 17 is used for control over piping lines. Next, set processed-water turbidity D from set processed-water turbidity selecting mechanism 18 is compared to turbidity D0 and the start and stop of filters 10 to which the water is branched are controlled as many times as fixed to exercise control over the ratio of the distribution side for unprocessed turbid water. Consequently, the processed water turbidity can be held below set value D by decreaseing the working ratio of filters.
