PURPOSE:To drastically increase the captured quantity into a group of fine gas bubbles and to sharply widen the application range of floating separation technique by providing a suction type gas bubble feeder where a porous liquid transfer pipe installed in mid-way of a water head difference liquid flow line is exposed to and provided in a gas atmosphere. CONSTITUTION:In a floating separator for suspended matter in liquid equipped with an absorption type gas bubble feeder 30 installed in mid-way of a water head difference liquid flow line, since a suction type gas bubble feeder consisting of a porous pipe 1 made of ceramics is used as the gas bubble feeder 30, large pressure loss energy as found in the conventional method using an air-diffusible pipe is not required. And owing to the system of sucking gas into water through the porous pipe 1, bubbles of large diameter as generated in the case of the air-diffusing pipe are not generated, but bubbles of extremely small diameter are generated. Therefore, the capturing efficiency of gas bubbles into liquid is extremely improved to increase the contact probability of bubbles with material to be separated, thus enabling contact capturing reaction to be made with high efficiency. |
