Summary: | A filtration device is provided in which wastewater, in the form of a colloidal solution containing microparticles, is guided to tank, circulated, and filtrated using a second filter. The device includes a gel film that is formed by suction on the surface of a first filter. The suction pressure in this process is made extremely weak to maintain the filtration capacity while extending intervals prior to clogging of second filter 2. Furthermore, a filtration device is realized with which the gel film of second filter that becomes adsorbed onto the surface of first filter can be separated readily by stopping the suction and filtration can be continued again thereafter. |
