Title: Method for clarifying waste water by filtration
Inventor: YAIDE NORIHIRO
IPC: C02F1/24
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To remove suspended matter with improved efficiency and to make the equipment compact and inexpensive by adding a pressurized gas or a pressurized dissolved gas-contg. liq. to a waste water to generate a fine bubble, depositing the suspended matter in the waste water on the bubble and introducing them into a filtration tank packed with a floatable filter medium. SOLUTION: The water 1 to be treated is introduced into a filtration tank 2 through a mixing tank 10, and the suspended matter (SS) in the water 1 is filtered by the filter bed 4 packed with a filter medium. In this case, the water 1 is brought into contact with pressurized water 11 in the mixing tank 10, hence the water 1 is pressurized, and the amt. of dissolved gas is increased. The pressure of the water 1 is then released to normal pressure to generate a fine bubble, and the SS is adsorbed on the bubble. The bubble and SS are then introduced into the filtration tank 2. Consequently, the filtration rate is increased, the equipment is made compact, and the consumption of chemicals is reduced due to the fine bubble. Further, the SS is enlarged by the fine bubble and made easy to filter, and the SS is removed more efficiently.
