Method of filtering |
| 摘要 |
A colloidal solution containing micro-particles can be filtrated using a second filter, and 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 keep the filtration rate fixed and to maintain the filtration capacity while extending intervals prior to clogging of the second filter. Micro-particles, mainly 0.15 mum or less, can thereby be removed.
