Abstract

PURPOSE: To ensure that bubbles move downwardly in a falling passage by a method wherein water to be treated is circulated with a static head of 0.5W7m Ag, in a water treatment device consisting of a falling passage, a rising passage, a storage tank and a pump line.
CONSTITUTION: By suitably operating a flow control valve 9 provided in the pump line 3, the pumping-up amount is adjusted so that the water level S2 in a head tank part 1a is 0.5W7m higher than the water level S1 in the rising passage 2, thereby reducing the height of the tank part 1a as much as possible and making the pump 3a and a blower 5a as small as possible. In addition, it is ensured that the bubbles move downwardly in the falling passage 1. When adjusting the pumping-up amount in the pump line 3, control of the discharge amount of the pump 3a or other various means can be utilized.
